Answer:
Ans:Insectivorous plants are the ones that derive their nutrients by trapping and consuming animals ,mainly insects.These plants mostly grow in places where the soil is deficient in certain nutrients.(eg -nitrogen)
The venus flytrap has leaves modified to trap insects.The inner surface of the leaves have short stiff hair.When an insect touches the hair ,the leaf snap shuts in within a second.The insect is then trapped and digested.
The leaf of the pitcher plant is modified to form a tubular pitcher -like structure.The inside of the pitcher is lined with downward pointing hair that does not allow any trapped insect to climb up and escape.The fluid at the bottom of the pitcher contains digestive juices that digest the trapped insect.
The leaves of the sundew plant have long ,thin structures called tentacles,which have drops of sticky substances called mucilage at their ends.Once an insect touches the tentacles ,it gets stuck in the mucilage and is unable to escape.It is then digested.
The slender leaves of the bladderworts bear a large number of very small,pear shaped bladder like structures which act like trap doors and suck in small insects in less than a second.
