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.
