WHAT ARE THE FUCTIONS OF THE FOLLOWING IN A SEED?
i) Seed coat ii) Micropyle
iii) Cotyledons iv) Radicle
v) Plumule
Answers
The endosperm is the food storage area of the seed. The purpose of the seed coat is to protect the seed from physical, temperature-related, or water damage. The seed coat also ensures that the plant seed remain in a state of dormancy
Micropyle (zoology), a differentiated area of surface in an egg, through which a sperm enters. The micropyle helps in absorbing the water at the time of germination of the seed.
A cotyledon is part of the embryo within the seed of a plant. Often when the seed germinates, or begins to grow, the cotyledon may become the first leaves of the seedling.
It is the embryonic root inside the seed. It is the first thing to emerge from a seed and down into the ground to allow the seed to suck up water and send out its leaves so that it can start photosynthesizing. The radicle emerges from a seed through the micropyle.
