Answer 1

Explanation:

All flowering plants produce seeds. The seeds are a tiny part of a plant which gives rise to a new plant. Different seed is found in different shapes, sizes, and colors. It can be a pip (like an apple), a nut (in walnut), or a bean (pea, pulses). Let’s find out more about it.

A seed has the following parts:

Seed coat: It is the outer covering the of seed. It protects the internal parts.

Seed leaves or cotyledons: Cotyledons are present inside the seed. Cotyledons absorb the food from the parent plant and store it for the embryo. They also protect the embryo. Some seeds have two seed leaves like gram, pea, bean, etc. Such seeds are called dicot or dicotyledonous. Some seeds have only one seed leaf. They are called monocot or monocotyledonous.

Embryo or baby plant: It is present inside the seeds which develop into a new plant. The embryo gives rise to a baby shoot (plumule) and root (radical).
