Describe insectivorous plants with suitable example. |
|
Answer» Those plants which in order to survive, trap insects and digest them are called insectivorous plants, e.g., drosera, dionaea, utricularia, pitcher plant. In pitcher plant, the leaf is modified to form a pitcher-like structure. The bright colour of the pitcher makes it attractive. The apex of the leaf forms a lid. Inside the pitcher, there are hairs which are directed downward. The mouth of the pitcher is sticky. When an insect lands in the pitcer, it slips and gets entangled into the hair present into the neck of the pitcher. As the hair are directed downwards, the insects are unable to escape out. The insect is digested by the digestive juices secreted in the pitcher. |
