The Venus flytrap is a symbol for “perseverance.” This is because the plant remains sulkily closed for a few hours after failing to capture a visiting fly before restarting. The mouth opens up once more to try againa fresh round with fresh prospects.

What is the Venus flytrap’s symbiotic interaction with insects?
The plant will produce acidic chemicals that will digest its victim once the flytrap has closed and the insect has been captured by the lobes and hairs of the plant. The Venus flytrap, in other terms, eats bugs alive! Considering that most plants produce their own food through photosynthesis, this is highly unusual for a plant.
What does the name Venus flytrap mean?
Originally called “Venus’s flytrap,” the plant’s popular name alludes to Venus, the Roman goddess of love. The species name, muscipula, is Latin for both “mousetrap” and “flytrap,” while the generic name, Dionaea (“daughter of Dione”), relates to the Greek goddess Aphrodite. The Latin word muscipula, which means “mousetrap,” comes from the words mus and decipula, whereas its homonym, muscipula, meaning “flytrap,” comes from the words musca and decipula (“trap”).
Historically, the plant was also referred to as “tippity twitchet” or “tipitiwitchet,” which may have been a subtle allusion to the plant’s likeness to human female genitalia. The phrase is comparable to tippet-de-witchet, which is made up of the words tippet and witchet (archaic term for vagina). In contrast, the name tippitywichit was a native term from either the Cherokee or Catawba languages, according to the English botanist John Ellis, who gave the plant its scientific name in 1768. The Renape term titipiwitshik, which means “those (leaves) which wind about (or involve),” is the source of the plant’s name, according to the Handbook of American Indians.
This typically activates defense mechanisms.
“These defensive mechanisms have undergone reprogramming in the Venus flytrap over the course of evolution. The plant now uses them to eat insects,” the professor further adds. The JMU researchers came to this conclusion by looking at thale cress (Arabidopsis thaliana), a non-carnivorous plant, for exactly the same pattern of gene activation as found in the Venus flytrap when it catches its prey.
The greatest match is found when thale cress is injured mechanically or when insects feed on it. The physiological responses too are similar. Injuring thale cress generates an electrical impulse that activates an important defense hormone called jasmonate. Touching the Venus flytrap’s sensory hairs activates the same hormone.
From that point on, the signal paths differ. To fend off insects, the hormone starts the production of substances that poison or deter insects, or make the leaves hard to digest. In this carnivorous plant, the hormone initiates the digestion of the meal and uptake of its nutrients.
“We have thus achieved our goal of decoding the molecular origin of the Venus flytrap’s carnivorous way of living,” Hedrich reports with pleasure. He has pursued this goal since 2010 within the scope of the “Carnivorom” project funded by the European Union (EU) to the tune of 2.5 million euros.
“We are now going to compare the genome of carnivorous plants, their protocarnivorous precursors such as Plumbago to plants in which carnivorous and non-carnivorous development stages alternate such as in Triphyophyllum or the tropical liana Ancistrocladus, which has gone on to abandon the carnivorous lifestyle. Ultimately, we want to know what equipment a plants needs to eat and live off animals.”
Possibly touching a Venus flytrap
Dionaea muscipula, the Venus flytrap, is uninspiring to poke with a finger. One of the plant’s traps can be made to close if you insert your finger into it and move it around. You won’t get hurt, but you might hurt the plant. The flytrap’s trap part is made up of leaves that can only close so many times before they pass away, therefore overstimulating them will only expedite their demise. Springing the plant’s leaves close also prevents them from being used for photosynthesis. People frequently assume that when instructed not to touch a Venus flytrap, it is for their own protection. In actuality, the plant is safeguarded by this warning.
Are Venus fly traps uncommon?
Venus flytraps are uncommon and under protection. 200 of them were dug up, according to NC authorities. According to a wildlife officer, a North Carolina man who was nabbed on Saturday with more than 200 Venus flytraps is now behind bars for stealing the endangered species.
What is the reputation of Venus flytraps?
The flowering plant known as the Venus flytrap is well recognized for its carnivorous eating style. Each leaf’s end has two lobes that are hinged together to form the “trap.” Trichomes, which resemble hairy projections, are found on the inner surfaces of the lobes, and when prey comes into touch with them, they force the lobes to close. Thigmonastya nondirectional plant response to being touched is the term used to describe this kind of movement. Only when the trichomes are touched repeatedly will the trap close, preventing the plant from wasting energy if no prey is present. To prevent the prey from escaping, the hinged traps’ edges are lined with tiny bristles that interlock as the trap closes. Although there are other carnivorous plants that actively catch their prey, the Venus flytrap is one of the very few that does this.
Can a human be harmed by a Venus flytrap?
After capturing the fly, the venus flytrap employs digestive enzymes to break down the fly’s soft tissue before ingesting it as a wholesome meal. A week after a catch, the trap reopens and is ready for another, using what’s left of the fly to draw in fresh prey.
Venus flytraps are powerful plants, yet they don’t always work. When larger insects get caught, like spiders, they can easily eat through the plant to get away, and if the plant absorbs the incorrect insects, it may suffer damage.
Do venus flytraps have brains?
According to research published in the 2020 issue of Nature Plants, Venus flytraps’ short-term memory is made possible by sophisticated calcium signaling. The leaves close when enough calcium is found in them.
Can a venus flytrap hurt a person?
A venus flytrap is incapable of harming a person. In fact, putting your finger in a venus flytrap will inflict more harm to the plant than to you because it will have to use more energy than is necessary.
The truth is that humans threaten venus flytraps considerably more than they do other species. If not properly cared for, these carnivorous plants can quickly be destroyed. For instance, they require special compost and cannot be fed tap water. See more below about this.
After the Venus flytrap shuts, what happens?
The Venus flytrap (Dionaea muscipula), one of the most well-known insectivorous (insect-eating) plants, uses an unusual system to lure, kill, digest, and absorb its prey. The Venus flytrap doesn’t eat and digest its prey for the customary non-plant purposes of gathering energy and carbon because it is a plant and can create its own food through photosynthesis. Instead, it primarily mines its prey for vital nutrients (nitrogen and phosphorus in particular) that are scarce in its acidic, marshy home. So, certainly, the digestive system of the Venus flytrap is fairly similar to that of an animal, but it serves somewhat distinct functions.
How does a stationary organism draw in, kill, break down, and absorb its prey? It first entices its prey with sweet-smelling nectar that is hidden on its leaves, which resemble steel traps. Unwary prey accidentally trip over the bristly trigger hairs on the leaf while looking for a reward and become imprisoned behind the interlocking teeth of the leaf edges. Each leaf has between three and six trigger hairs on its surface. The cells on the leaf’s outer surface expand quickly if the same hair is touched again, or if two hairs are touched within a 20-second period, and the trap closes swiftly. If uric acid or other insect secretions activate the trap, it will tighten its grip on the prey and create an airtight seal. (If tripped by an onlooker or a dead branch falling from the sky, the trap will reopen after about a day.) Once the trap is shut, fluids are released from the digestive glands that line the inside edge of the leaf, killing bacteria and fungi while also dissolving the soft parts of the prey and dissecting the insect with enzymes to release the vital nutrients. Five to twelve days after capture, the trap will reopen to release the exoskeleton that was still inside the leaf after it has taken these nutrients. The trap will stop catching prey after three to five meals and spend the next two to three months purely photosynthesizing before falling off the plant. A Venus flytrap should not be overstimulated; after about 10 unsuccessful attempts to close the trap, the leaf will stop responding to touch and become just a photosynthetic organ.
The coastal North and South Carolina sand shrub bogs are where the Venus flytrap lives, and it is categorized as an endangered species there. Venus flytraps are supported by an ecology that is frequently burned, which eliminates rival plants and causes the soil’s nitrogen to volatilize. Because they get three-quarters of their nitrogen from insect food, Venus flytraps have a monopoly on the nitrogen market right after a fire. However, competition from other plants limits the Venus flytraps’ access to light and insects after ten years, and populations start to drop. Venus flytraps offer an interesting illustration of how organisms adjust to challenging circumstances, in this case acting as predators to compensate for the lack of nutrients in the nearby soil.
How intelligent are Venus flytraps?
The scientists inserted the calcium sensor protein gene GCaMP6 to observe what occurred when a stimulation was received. Then they would apply a stimulus, followed by another stimulation, to see if the calcium content in the plant’s cells rose. Ca2+ had been suspected in earlier research, which is not surprising given that calcium ions are required for numerous biological activities. One sensory hair received the first stimulus via a needle. Within 0.02 seconds, the leaf’s Ca2+ concentration surged noticeably. Although it fell for a little while after that, the leaf really started to glow when the concentration spiked in response to the second stimulus.
“Ca2+ ions are present in large levels outside of cells but in relatively small amounts inside of cells prior to activation. Ca2+ from outside the cell enters the cell when it recognizes an external stimulus. “GCaMP6f themselves in cells create fluorescence when GCaMP6 binds to Ca2+,” Hasebe explained.
If the interval between shocks was less than 30 seconds and the concentration of Ca2+ was sufficient, the trap would only close. Even though the Venus flytrap lacks a brain, it can retain short-term memory with enough of a calcium ion boost. One leaf “jaw” to the next was illuminated. There are sensory cells at the base of the hair that alert the Venus flytrap when to seize a bug, therefore there was a particularly noticeable increase there. According to Hasebe, this meat-eating plant may not have always been interested in flies, even if it exhibits an increase in calcium when cues cause it to close its trap over prey.
When plants are consumed by insects, he explained, “calcium waves are found in non-carnivorous plants.” “Such preexisting systems that were used for purposes other than carnivory may have been recruited by the progenitor of Dionaea.”
It actually took Suda several years of trial and error to figure out how the Venus flytrap could remember. He only understood what could eventually shed light on the plant’s enigmatic memory when he spotted a transgenic plant that had been given the GCaMP6 gene glowing in the dark. This finding might serve as the starting point for further investigation into the origins of carnivory in plants.
Can my Venus flytrap be saved?
- Traps typically begin to die back after capturing and digesting prey. When a trap expires, a bigger one will take its place.
- It’s possible that your flytrap will bloom in the spring. Cut off the blossom if you want the plant to continue producing traps. The blossom may develop a seed pod in approximately a month if you let it grow. The Venus flytrap can take up to three years to mature from the time the seeds are planted.
- Normally, venus flytraps only last up to a year, however under ideal circumstances, a plant can live for about 20 years.
