Exploring Venus Fly Trap Adaptations

carnivorous plants live on nutrient poor habitats to survive such conditions these plants depend on animal food to actively catch insects the Venus fly trap grows its Leaf endings into beled capture organs searching for food insects like flies and ants also visit carnivorous plants when the insect eventually gets in contact with a touch sensitive treap surface the capture organ closes and engages the victim how the fly trap recognizes animal prey in order to mimic an insect scientists display trigger has manually and record electrical events the so-called Action potentials this finding documents that touch a mechanical stimulus is converted by the trigger hair into an electrical wave two action potentials are required to close the Trap the trapped insect struggles to escape the green cage repetitively touching the trigger ha trains of action potentials excite the flly Trap the panicking insect elicits more than 50 Action potentials per hour these electrical waves are translated into the flooding of the Trap the Trap turns into a green stoage to study the fly trap's response to an increasing number of touch stimuli capture organs that had been repetitively stimulated were harvested following the extraction of the genetic material the profile of the touch induced trap genes is analyzed the molecular analysis shows that from the second Action Potential on touchon are being activated toucha Mones induce the production of digestive enzymes prey meat disintegrates into its building blocks glands on the inner surface of the green stomach absorb the pre derived nutrients the Venus fly trap recognizes a prey by the number of contacts with its touch sensors mechanical stimuli are converted into action potentials two such electrical signals close the Trap from the the second Action Potential on electrical signals are translated into touchon action from the third stimulus on digestive enzymes get produced and with the fifth signal uptake of nutrients is initiated
