  • The main parts of a flower are: Sepals, Petals Stamen and pistil.

(42) Ans: The process by which green plants use sunlight to make food from carbon dioxide and water is called photosynthesis.

  • The leaves make food for the plant by the process of photosynthesis.
  • Chlorophyll present in the green leaves helps in trapping energy from sunlight.

(43) Ans: Tap root: Tap root is a straight tapering root which grows vertically down into the soil and gives out branches on all the sides.

Example – Pea plant and Neem tree.
