The cactus family is known for its prickly spines, which are actually altered leaves. The kind of leaves that a maple or oak tree has are not present on cacti. But in the distant past, they might have had leaves that were at least somewhat more similar. Due to the fact that they aid the plants in surviving in hot, dry situations, those leaves eventually changed into the prickly spines we see on cactuses today.
“They could serve as a defensive strategy to prevent herbivores, or animals that consume plants, from consuming the cactus. But spines also produce shade! “Kimberlie McCue says.
“When you are covered with spines, those spines are throwing shadows on the cactus’ body as the sun moves across the sky. They are tiny umbrellas for shade.”
All cacti are native to arid regions, and some can even survive in dry climates. How do they acquire water to exist, then? Kimberlie informs us that these plants can be found close to the water.
“There will be fog coming off the ocean in the morning. Water condenses on those spines, forming tiny droplets, which then flow down the spine, to the plant’s body, to the soil, and to the roots.”
As they hold the soil in place and offer shelter to birds and other creatures, cactuses are also crucial components of their desert ecosystems. In exchange, such animals and birds assist in pollinating the cactus flowers. Cacti are a significant local source of food for people.
Cactuses are unfortunately threatened by people who illegally steal natural plants from their surroundings. According to Kimberlie McCue, being cautious when purchasing cactus plants is one method to ensure that cacti remain healthy and numerous. Before you buy, find out where the cactus came from and confirm that the vendor is being a responsible steward of these plants.
Why are there needles on cactus plants?
The prickly pear cactus found in Mexico has the potential to become a fantastic energy source in the future.

Answer:
Cacti are among my favorite plant species, and their needles undoubtedly make them distinctive. In many respects, the needles that cover cactus are essential to their survival. Since many cacti are found in dry environments, these plants need to store a lot of water in order to thrive. In fact, according to scientists, water makes up between 90 and 94 percent of a cactus plant. Cacti are ideal treats for thirsty species due to their high water content. Animals that consume cactus in the wild include quail, kangaroo rats, sheep, desert tortoises, as well as a variety of insects. In order to stop thirsty or hungry animals from eating or harming the plant, cacti contain needles.
Additionally, you could see that the color and texture of cactus spines might vary. While some spines are fluffy, others are stiff. The color of the spines can also vary, from white to gray to pink! Because of these variations in spine color and texture, cactus can more effectively blend into their surroundings (i.e. camouflage). Therefore, a second reason cacti have needles is to enable them to conceal from harmful species.
Heat is a significant issue in desert regions where there are many cacti. The needles of a cactus can offer protection from the sun so that it can thrive in these scorching temperatures. Although it may not seem like a single needle may offer much shade, several cacti species have needles that are grouped closely together. The plant is shaded by these spine clusters, which resemble small umbrellas. These spines provide shade for the cactus, which helps keep water from evaporating and causing water loss.
All in all, cactus use their spines as protective and hiding mechanisms against potential predators. Additionally, they give the plant shade, which keeps it cooler and prevents water loss.
What happens if you take a cactus’ needles out?
New areoles form and new spines sprout on a healthy cactus plant as long as general growth continues. Be tolerant. Some cacti have a slow rate of growth, therefore it could take some time before new areoles are produced.
By fertilizing it and placing the cactus in the morning sunshine, you can help it grow. eat by using a cactus
Why do cacti lack leaves in favor of tiny needles?
Being a desert plant, your goal is to prevent water reduction. As strange as it may appear, cactus spines really work to prevent water loss in cacti.
Cactus spines primarily stop cacti from losing water by decreasing air flow around the plant. Air flow is broken up by spines, which can aid in lowering evaporation. A buffer zone with air that is a little bit more humid can also be produced by the trapped air surrounding the cactus.
This is significant because plants lose a lot of water as it evaporates off their leaves.
Can I clip the cactus’ needles off?
“Dieter claims that it is a natural response. However, if at all possible, “you’re better off not using your fingers.
It’s all too simple to make things worse, especially if you attempt to remove cholla bits with your own hands. Nobel once seen the results of this choice in a couple who had been harmed by the infamous teddy bear cholla in the Saguaro National Forest. As one of the couple initially got trapped on a piece of stem, his wife became caught when she attempted to remove him.
According to Nobel, the more they fought, the deeper their spines went.
They were holding hands with the torturous joint while yelling for aid as they walked along the road in an uncomfortable embrace. By removing the spines with a pair of wire cutters, Nobel was able to liberate the pair.
Before dealing with the individual prickers, Puente-Martinez also suggests cutting the section of stem to which the spines are attached, like he did in Mexico when his friend’s lip turned into a pincushion. He suggests using a pair of scissors or pliers to cut the stem-attached spines, leaving about a half-inch piece of spine still embedded in your flesh. The stem and some of the spines can also be worked free using the teeth of a comb. If you don’t have any tools on hand and the spines are stuck in your hand, another option is to lean over, step on the stem joint, and pull your hand free. However, this will probably result in a little more blood as the spines are drawn out.
Depending on the kind of spine you have, there are different things you should do next. You can try using a pair of tweezers to remove larger, needle-like spines. The straight spines on saguaro cacti are the easiest to remove, however barbed cholla spears or hooked spines like those on barrel cacti require a little more effort to remove.
When you try to remove cactus spines, they frequently break, leaving bits under your skin. According to Trager, “[the area] will stay sensitive to the touch, so you’ll know if you haven’t gotten it all.
To find the spine fragment, you can try using tweezers or a needle, however they may be transparent and difficult to find.
According to Trager, trying to manipulate the spine with a needle frequently results in more harm than the spine itself did. “It might not be worth performing unless you can truly see the broken base of the spine just under the skin or something. According to him, some of the discomfort from implanted spines can be relieved by soaking in a warm Epsom salt bath.
Why are cacti so uncomfortable?
Anyone who has come into contact with a jumping cholla cactus can attest to the fact that it is both excruciatingly painful and challenging to resolve because the cactus’ spines are notoriously difficult to remove.
Cactus spines have a variety of purposes, including defense and the storage of essential water in arid regions, although some are considerably more difficult to remove than others. Researchers have now determined the cause.
Microstructure Matters
The function of the spines, particularly their capacity to pierce animal skin, was tested by Stephanie Crofts and Philip Anderson of the University of Illinois on six different cactus species. Their findings, which were reported in the Proceedings of the Royal Society B, demonstrate that the microstructural characteristics that enhance a spine’s capacity to pierce flesh also raise the barrier to removal.
With their shingled, overlapping barbs, cholla and other barbed cactus spines in particular resemble porcupine quills. Compared to non-barbed spines, these barbs more easily pierce and entangle flesh.
According to Anderson in a news statement, “The barbs grab on your muscle fibers, making it tough to remove them.
The two also experimented with golden barrel, brittle prickly pear, and a few other common cactus species in addition to jumping cholla. They pierced skinless chicken breasts, hog shoulders with the skin still on, and a succession of rubbers with various densities to determine the structure of each plant after studying the spines under a scanning electron microscope to learn more about it. According to their experiments, barbed spines function as razor-sharp blades that may readily pierce skin.
According to Anderson, the cholla spine needs to be able to penetrate the target with just a mild brush in order to puncture the target efficiently. ” It must also be quite challenging to remove at the same time.

Stuck On You
Barbed spines, like cholla, emerged out of the chicken breasts with a tissue-coated exterior. The researchers believe that some of the barbs were left behind in the flesh because they did not emerge clean from the pork samples.
The plains prickly pear’s spines checked out took the most effort to remove from chicken breasts. On the other hand, cholla spines proved to be the most difficult to extract from pig tissue; tests revealed that one cholla spine was capable of hooking into flesh with sufficient force to lift half a pound of pork by the skin.
That’s both quite frightening and clever. Cholla spines also have a reproductive function. Chollas have spines that hook onto a person or animal’s muscle fibers so strongly that it frequently tears off a piece of the cactus, which is then moved to a new area and can start growing as a new plant.
Do you actually get jumped at by leaping cacti?
The leaping cholla, also known as the teddy bear cactus, gets its common name because if you come too close, a section will break off and fly towards your body. A flying cactus, indeed. See the jumping cholla in action by watching the video up top! Avoid being a victim!
What to do if a cactus is touched?
Cactus spines can be easily removed with a pair of tweezers if you manage to get one or two stuck in the flesh. But what if you end up being one of the unfortunate people who gets stuck with a hand, foot, or butt full of needles? Elmer’s Glue works well for this, just spread a thin layer of it over the surface.
Once the glue has had time to dry completely, allow it to sit for a while before peeling it off. Your skin-piercing needles will rise to the surface and be pulled out by the glue. If you get a good foot- or handful, you might need to repeat a number more times.
Using duct tape is a different choice that I haven’t personally tested but that has received excellent recommendations (should you be out of glue.) However, since you’ll have to apply pressure in order to trap the needles, this seems uncomfortable.
In either case, when you remove the spines, make sure to thoroughly cleanse the area with antibacterial soap. You don’t want the injury to contract an infection.
If portion of the needle does not stick out above the skin, you can find it more challenging. You could want to leave it in your skin for a few days if it isn’t hurting you. The needles are pushed to the top by the body, which makes them simpler to catch.
Call an ambulance if you experience a serious fall and become coated in needles, but in reality, it would be best to stay clear of the cacti altogether.
Are cacti toxic to people?
Are Cacti Toxic to People? Humans cannot be poisoned by cacti. Cacti are only harmful if you eat them, which might result in diarrhea and stomachaches. It’s advisable to avoid touching or eating cacti because some people may be allergic to their thorns.
Cacti may be consumed?
You can either leave the pads whole, cut them into strips, or chop them into cubes, depending on how you intend to use this vegetable. Cacti that are edible can be eaten raw or cooked. They can be grilled, sautéed, boiled, simmered, or deep-fried. Their ideal serving texture is soft and crispy. The texture of overcooked pads will be slimy. Combine them with various ingredients to create a range of wholesome, nutrient-rich recipes. Here are some recommendations:
You might need to switch the water you’re using to boil the pads and re-boil them. It’s possible that the sap coming from the pad is thick. As a general rule, the sap will be thicker the thicker the pad. After draining, the pads are washed in cold water. Why not prepare a traditional Mexican salad with diced tomatoes, cilantro, jalapenos, onions, and lime juice? Salt and pepper are other good additions.
Grilling
Season the pads well with salt and pepper if grilling them. When the pads are somewhat brown in color and soft to the touch, they are prepared. Additionally, you may season them with a dash of salt, a squeeze of lime juice, and a little olive oil.
Cactus pads can be added to various meals, either raw or cooked, to create flavorful, nutritious foods. They can be blended into a smoothie, or they can be diced and added as a topping to yogurt or cereal. Why not attempt incorporating them into stews, casseroles, and eggs. They make a delicious addition to quesadillas and salsa. You can choose to consume this adaptable, healthy vegetable alone, in a robust vegetable soup, in a fruit or vegetable salad, or even simply by itself! It can also be prepared into a jelly. Cactus pads can also be pickled and used to other meals as a condiment.
