the sunlight. The leaves then start appearing. The young plant, called a
seedling, soon grows into an adult plant. In time, the adult plant will start

producing flowers. Flowers will make seeds, and the cycle will repeat.

Air supplies itself to the seed for breathing. Water softens its seed coat and
also changes the stored food in the seed leaves into a soluble form for the use

of the baby plant. Warmth makes the seed active.

Research

Soak a few seeds of wheat, gram, moong, mustard, maize, rice, and
groundnut in water for a few hours. Find out which of these seeds are
made up of two cotyledons.

Record your observations below.

Dispersal of Seeds

Often, seeds get scattered, which leads to the growth of new plants. The
process by which seeds get scattered away from the mother plant is called

dispersal.

Let us learn about the different ways seeds get dispersed.

By Wind

The wind carries away many small seeds that are light and have wing-like
