Question

Write short notes on:
- Normal functions of leaf
- Parasitic root
- insectivory
- Typical leaf

Answer 1

1)The leaves perform three main functions such as manufacture of food, interchange of gases between the atmosphere and the plant body and evaporation of water. It is the primary function of green leaves.

2)PARASITIC ROOTS OR HAUSTORIA:Adventitious roots found in the PARASITIC PLANTS are called PARASITIC ROOTS.Plants which depend on host plants completely or incompletely are called PARASITIC PLANTS.he plant give shelter and food material to the parasite is called the HOST PLANT.Parasitic plants absorb water and food from other plants

3)An insectivore is an animal that eats only or mainly insects. ... A carnivore is an animal that eats other animals, and an insectivore is a more specific type of carnivore: one whose diet is mainly insects. Insectivores include many lizards, frogs, and spiders.

4)Structure of a Typical Leaf. Each leaf typicallyhas a leaf blade called the lamina, which is also the widest part of the leaf. Some leaves are attached to the plant stem by a petiole. Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves.
