ANSWER:
Ans 6 a. The various parts of a plants are:
Roots: They absorb water and minerals from the soil and also anchor the plant firmly in the soil.
Stems: Spread out branches to bear leaves, flowers and fruits, conducts water and minerals to different plant parts and performs functions of storage, support, protection and vegetative propagation.
Leaf: They are called ‘food factories’ of a plant. They carry out photosynthesis, a process by which they synthesize their food.
Flower: In plants, flower is the functional unit concerned with the sexual reproduction of plants.
Fruits: They have different shapes and contain one or more seeds.
b. The functions of the roots are as follows:
they help in anchoring the plant to the soil.
they also help in the absorption of water and nutrients from the soil.
c. Importance of classification:
(i) Classification ensures uniformity. All life forms can be studied on a common platform.
