What is the function of a seed coat and the cotyledons?
The cotyledons provides a source of food to the seed and seedling that is germinating, while the seed coat protects it.
What is the tiny hole in the seed-coat called?

micropyle
What are the small pores on the seeds?

What are the three parts of a seed and what is the purpose of each part?
Seed coat, micropyle, endosperm and embryo are major parts of a seed. The seed coat protects, micropyle allows water to move in, endosperm nourishes the embryo and on germination a new plant emerges from the embryo.
What is the function of the micropyle?
The micropyle opening allows the pollen tube to enter the ovule for fertilization. It absorbs water for germination. It provides for the diffusion of respiratory gases.

What is the structure of a seed?
A seed has a seedcoat, perisperm, endosperm, embryo, funicule & micropyle etc.
What is the tiny hole in a seed?
