How did the Venus Fly Trap evolve?
The venus fly trap evolved from a letter plant when that plant ate a poekmon power crystal. (oh, and Misc - it wouldn't, not unless some random mutation caused it to stop producing the sticky fluid, and the new breed flourished more.
How did the flytrap evolve?
The flytrap, and one other carnivorous snap-trap plant which grows underwater, evolved from a more conventional relative that had sticky leaves. Over time, the plants added elaborate structures and weapons such as trigger hairs and teeth to trap and immobilise their meaty prey, botanists say.
How did the Venus flytrap get its sticky leaves?
The Venus Flytrap descended from an earlier plant that had sticky leaves that acted as flypaper. First the ancestral plant must have adapted to move its tentacles and leaves in a particular direction, giving it a greater chance of sticking to and engulfing a passing insect. Next it sped up how quickly it detected prey and tried to respond.
Is the Venus flytrap a plant or animal?
"In his time and ours, most of us feel that plants are passive, harmless, and can't move. But the Venus flytrap acts like an animal, it moves fast and eats fresh meat."

How has the Venus flytrap adapted?
Cool Adaptation They live in nitrogen poor environments so they have adapted to gathering additional nutrients from insects. The leaves of the Venus flytrap are wide with short, stiff trigger hairs. Once an object bends these hairs the trap will close.
How did carnivorous plants evolve?
' About 70 million years ago, when dinosaurs roamed the Earth, a genetic anomaly allowed some plants to turn into meat eaters. This was done in part, with a stealthy trick: repurposing genes meant for their roots and leaves and using them instead to catch prey, a new study finds.
Where did Venus flytraps originate?
While flytraps are cultivated throughout the world, they are native to only a small area of the coastal plain in North and South Carolina.
How Venus flytraps evolved their taste for meat?
How does a plant develop a taste for flesh? In the play Little Shop of Horrors, all it takes is a drop of human blood. But in real life, it takes much more. Now, a study of three closely related carnivorous plants suggests dextrous genetic shuffling helped them evolve the ability to catch and digest protein-rich meals.
Why is a Venus flytrap not an animal?
The Venus flytrap is a flowering plant best known for its carnivorous eating habits. The “trap” is made of two hinged lobes at the end of each leaf. On the inner surfaces of the lobes are hair-like projections called trichomes that cause the lobes to snap shut when prey comes in contact with them.
Can you touch a Venus flytrap?
A single touch can provide sufficient mechanical stimulation to trigger Venus flytrap closure.
Can Venus flytraps survive without flies?
Although flytraps are carnivorous, they can go long periods (a month or two) without eating insects. If you grow them outdoors, they'll get enough to eat naturally. If you're growing Venus flytrap indoors, you'll have to feed them bugs periodically.
Are Venus flytraps rare?
Venus flytraps are rare — and protected. A thief dug up 200 of them, NC officials say. A North Carolina man caught Saturday with more than 200 Venus flytraps is in jail for taking the protected plants, according to a wildlife official.
Why can't Venus flytraps eat ants?
Most ant species are small enough to fit inside the leaves of a Venus flytrap. Venus flytraps sometimes struggle to capture bugs that are too large for their leaves.
When did Venus flytraps first evolve?
about 65 million years agoThey evolved from simpler carnivorous plants about 65 million years ago; the snap mechanism enables them to catch larger prey relative to their body size. The fossil record suggests their ancestors were much more widespread, especially in Europe. Flytraps are improbably elaborate.
Are there man eating plants?
In his 1955 book, Salamanders and other Wonders, science author Willy Ley determined that the Mkodo tribe, Carl Liche, and the Madagascar man-eating tree all appeared to be fabrications: "The facts are pretty clear by now. Of course the man eating tree does not exist. There is no such tribe."
How big is the biggest Venus flytrap?
2.4 inThe largest individual trapping leaf from a Venus flytrap (Dionaea muscipula) is a specimen of the cultivar “Alien”, which was verified to be 6.1 cm (2.4 in) across the midrib on 7 June 2021.
How many times did carnivorous plants evolve?
Abstract. Carnivory has evolved independently at least six times in five angiosperm orders. In spite of these independent origins, there is a remarkable morphological convergence of carnivorous plant traps and physiological convergence of mechanisms for digesting and assimilating prey.
Why did carnivorous plants evolve to eat insects?
The ancestors of today's carnivorous plants needed to get their nutrition (particularly nitrogen and phosphorus) from another source, and the high light levels meant they could afford to be less efficient at photosynthesis by turning their leaves into traps.
How did plants evolve?
Plants are thought to have evolved from an aquatic green alga protist. Later, they evolved important adaptations for land, including vascular tissues, seeds, and flowers. Each of these major adaptations made plants better suited for life on dry land. The oldest fossils of land plants date back about 470 million years.
Why have some plants evolved adaptations that allow them to be carnivorous?
To complete the lack of nutrients of some soils, carnivorous plants can catch and absorb nutrients from a prey, thanks to an exclusively biological mechanism.
How does Venus flytrap work?
So, the Venus flytrap has sensors on it that tell the plant that there is prey present. Then it snaps shut ( that is the coolest ting about the plant, but we're not actually going to go into that here). Then a liquid engulfs the prey and digestion happens, then a different liquid is exuded and this facilitates the transport of nutrients into the plant.
Why do Venus flytraps have a trait?
Venus flytraps are plants that capture and then digest insects (or other small critters). The ultimate reason they do this may have to do with nutrients. Capturing and absorbing the tissues of insects provides nitrogen and some other often rare nutrients. So, the adaptation is to nutrient poor environments. One might guess that this is a trait that was selected for in nutrient poor environments, or one might guess that it is a trait that emerged largely by accident and then allows plants that do this to do better in nutrient poor environments. Or, one might not be too concerned by this distinction and guess that both features of the emergence of a trait are likely to be involved in the evolutionary history of a particular species and its adaptations. But, again, I digress.
How does a fly trap work?
To catch an invertebrate that has blundered into its snare, the flytrap relies on an ancient alarm system. It starts ringing when the victim jostles trigger hairs . The hairs in turn generate electrical impulses that somehow stimulate glands in the trap to produce jasmonic acid—the same signal that noncarnivorous plants use to initiate defensive action against herbivores. Patterns of gene expression in the two kinds of plants confirm the similarity...
What is a flytrap?
He told me, "The flytrap develops from tips of Dionaea leaves. So, the trap is a leaf on one side. The inner surface of the trap is covered by a turf of glands, and these glands express genes one otherwise finds in roots. So, the trap is a leaf with root function. Most likely, to serve carnivory, Dionea modified a transcription foactor or promoter of root genes and so directed them into the glands."
Is a flytrap a root?
Experiments showed that many of these genes are the same ones expressed in the roots of other plants. “We looked at each other and said, ‘Yes, it's a root,’” Hedrich says. “It made immediate sense,” because the flytrap draws its nutrition not from soil, but from its prey.
What is Venus flytrap?
The origin of the voracious Venus flytrap has been uncovered. The flytrap, and one other carnivorous snap-trap plant which grows underwater, evolved from a more conventional relative that had sticky leaves. Over time, the plants added elaborate structures and weapons such as trigger hairs and teeth to trap and immobilise their meaty prey, ...
How did Venus flytrap and waterwheel become accomplished hunters?
They started by comparing snap-traps with other carnivorous plants known as sticky traps. The two types look very different.
What are the advantages of Venus flytraps?
Waller also suspects that engulfing and sealing in prey may also provide other advantages to the Venus flytrap and waterwheel. It stops other more sure-footed predators coming along and stealing a captured insect or spider, he says, and any nutrients being washed away by water or rain before the plant can digest them.
What is the difference between a snap trap and a sticky trap?
While snap traps have gaping leaves, sticky traps have small leaves that are covered by simple stalks, which are often covered in sticky glue. Many sticky trap plants belong to the genus Drosera, such as the circumboreal sundew ( Drosera rotundifolia ), and come in various forms.
Why are Venus flytraps called snap traps?
Both are known as snap-traps because they actively hunt animals, snapping shut specially adapted leaves to trap any hapless creature that crosses them. The Venus flytrap closes around an insect in just 0.3s or faster, while the waterwheel use thin translucent traps to snare copepods and other aquatic invertebrates.
How many times have carnivorous plants evolved?
Carnivorous plants come in many forms, and are known to have independently evolved at least six separate times.
Where does Venus flytrap live?
Answering such questions is particularly important because the Venus flytrap is becoming increasing rare in the wild, and should be listed as endangered in the US, where it only lives in North and South Carolina, says Waller.
How does Venus flytrap get its energy?
Like all plants, the Venus flytrap gets its energy from the sun in a process called photosynthesis. It digests insects and arachnids to get nutrients that are not available in the surrounding environment.
What is Venus flytrap?
The Venus flytrap is a flowering plant best known for its carnivorous eating habits. The “trap” is made of two hinged lobes at the end of each leaf. On the inner surfaces of the lobes are hair-like projections called trichomes that cause the lobes to snap shut when prey comes in contact with them. This type of movement is called thigmonasty—a ...
Why do Venus fly traps interlock?
There are other carnivorous plants in the wild, but the Venus flytrap is one of the very few that exhibits motion to actively trap its prey.
How long does it take for a Venus flytrap to digest?
Ants, beetles, grasshoppers, flying insects, and spiders are all victims of the flytrap. It can take a Venus flytrap three to five days to digest an organism, and it may go months between meals.
Where is Venus Flytrap native to?
The Venus flytrap is endemic to North and South Carolina, but it has been introduced to a few other states, including Florida and New Jersey. It is popular as a potted plant in many parts of the world, but unfortunately most of the Venus flytraps sold have been cultivated or collected from declining wild populations.
Is Venus flytrap endangered?
The Venus flytrap is internationally listed as vulnerable. It is also under consideration for federal listing on the U.S. endangered species list. This species is threatened by overcollection, habitat destruction, and fire suppression .
How do Venus fly traps reset?
To reset the trap, the doors are slowly opened in a metabolically demanding procedure , thus it is important that they close only on edible material. Flytraps have very sensitive detectors positioned exactly where they need to be—near the base of the leafy doors. These distinguish flies from falling forest fragments and communicate with the trigger. Venus flytraps’ digestive glands manufacture a cocktail of proteins specialized for multi-tactic nutrient harvesting. In the end, only the insect’s empty exoskeleton is left.
How do flytrap doors work?
But much more than this is required for the plant’s unique feeding mechanism. The flytrap doors must move in a particular direction (toward each other) and be shaped as mirror images so that their margins can seal around the digesting prey. The doors’ rapid closure is accomplished by the combination of precisely balanced three-dimensional structure with millions of tiny calcium ion pumps that help set the trap. The margins of the doors also have interlocking cilia that are the right length and strength to imprison the ensnared victim.
Why do flytrap doors have mirror images?
The flytrap doors must move in a particular direction (toward each other) and be shaped as mirror images so that their margins can seal around the digesting prey.
Do fly traps have to be in place at the same time?
Thus, all of the specifications for each part of the trap must be in place at the same time, all at once, for any of it to work. It seems therefore that they could not possibly have accrued by gradual Darwinian additions. Rather, the specificity of the flytrap’s features requires the whole mechanism to have been engineered by a clever genius.
