The seed is a reproductive structure that has a baby plant inside it, and also it has food stored for the growth of the baby plant. The hard outer cover that protects the baby plant inside is called testa. The part of the seed inside the testa that stores food for the tiny baby plant until the baby plant starts producing its own food by photosynthesis, is called cotyledon or cotyledons, and there can be one or two cotyledons.
The tiny baby plant inside the seed is called embryo. Embryo has two parts, radical and plumule. The radical is an embryonic root.
which grows and develops into the root system of the plant, and the pumule is an embryonic shoot that grows and develops into the shoot of the plant. The pumule usually has two visible leaves with a growing point enclosed between them. There is a scar or mark left on a seed coat by its former attachment to the ovary wall. which is known as Helium on the bean seed. We also call the Helium as the eye.
Then there is a tiny hole in the testa opposite the tip of the radical and it allows the water to enter the seed and it is known as the micropyle. Now we know all parts of the seed. Thank you so much for watching don't forget to like comment, and share this video.
