Seed facts

Seeds are the matured ovules. Mature seeds of different plants show great variation in shape, size and appearance.
  • The outer portion of the seed which gives protection is called the seeds coat or testa.
  • On removing the seed coat, we can see two fleshy cotyledons which stores the food for the growing plant.
  • A short curved axis is present to which the cotyledons are attached. It has two parts, the plumule which develops into shoot and the radicle which develops into root.

Under appropriate conditions of moisture, warmth and air, the seed germinates to produce a new plant.
