SEED FORMATION

SEED FORMATION

All flowering plants produce seeds. The seeds are a tiny part of a plant which gives rise to a new plant. Seeds 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.

SEED AND ITS PARTS

A seed has the following parts:

SEED COAT:

· It is the outer covering the of seed. It protects the internal parts.

EMBRYO OR BABY PLANT:

· It is present inside the seed which develop into a new plant.

· The embryo gives rise to root and a baby shoot.

SEED LEAVES OR COTYLEDONS:

· Cotyledons are present inside the seed.

· They absorb the food from the parent plant and store it for the embryo.

· They also protect the embryo.

MONOCOT SEEDS/DICOT SEEDS

MONOCOT SEEDS:

· Monocots have only one seed leaf inside the seed coat. It is usually a thin leaf. They are also called monocotyledonous.

· When a monocot seed germinates, it produces a single leaf.

· The leaves of monocots are often long and narrow, with their veins in straight lines up and down the leaf.

· The stems of monocots are usually unbranched and fleshy.

· Monocots have a fibrous root system.

EXAMPLES:

All Grasses, Rice, wheat, maize, bamboo, palm, banana, ginger, onion,
garlic, lilies, daffodils, iris, orchids, bluebells, tulips.

DICOT SEEDS/Dicotyledonous:

· Dicots have two seed leaves inside the seed coat. They are usually rounded and fat.

· When a dicot germinates, it produces two seed leaves. They contain the food for the new plant, so they are usually fatter than the true leaves.

· Leaves of dicots come in many different shapes and sizes.

· The veins go from the central midrib to the edge of the leaf, forming a netted pattern all over the leaf.

· The stems of dicots are usually tough.

· They can grow wider each year and are usually branched.

· Dicots have a tap root system.

EXAMPLES:
gram, pea, bean Bitter gourd, rose,hibiscus, Chickpea, Litchi, Mango, Neem.
