Venus flytrap The
Venus flytrap can count to two and five in order to trap and then digest its prey. The Venus flytrap is a
carnivorous plant that catches its prey with a trapping structure formed by the terminal portion of each of the plant's leaves, which is triggered by tiny hairs on their inner surfaces. A Venus flytrap's reactions can occur due to electric and mechanical, or movement-related, changes. When an insect or spider crawling along the leaves contacts a hair, the trap prepares to close, snapping shut only if a second contact occurs within approximately twenty seconds of the first strike. The requirement of redundant triggering in this mechanism serves as a safeguard against wasting energy by trapping objects with no nutritional value, and the plant will only begin digestion after five more stimuli to ensure it has caught a live bug worthy of consumption. There are two steps, which are a closed and locked state, that a Venus flytrap undergoes after its open state and before
digestion, which differ due to the formation of the trap. two trigger hairs must be touched in succession within 20 seconds of each other or one hair touched twice in rapid succession, The number of days that the trap remains closed will depend on whether or not the plant has caught prey. Most plants accumulate starch by day, then metabolize it at a fixed rate during night time. However, if the onset of darkness is unusually early,
Arabidopsis thaliana reduces its use of starch by an amount that effectively requires division. However, there are alternative explanations, such as feedback control by sensing the amount of soluble sugars left. As of 2015, open questions remain. ==See also==
