Question

Describe the structure of a monocot seed.

Answer 1

Hint: A monocotyledonous seed has a single cotyledon in it with a thick seed coat and it fuses with the pericarp. These seeds are endospermic in nature. The cotyledons in the monocot seed are called scutellum and are provided with the shoot axis.

Complete answer:
> The monocot seed has the outer seed coat and the inner seed coat. Within these layers the embryo is present. This monocot seed is differentiated with the separate axis. The part of the axis that is present in the lower part of the seed is called radicle. This part covered by the sheath is called coleoptile. The part of the axis that is present in the upper part of the stem is called plumule. The plumule is covered by a sheath called coleoptile. After the germination of the seed, the water enters into the hole of mycorrhiza and the seed bulges.
> This causes the growth of the seed, in which the stem part of the seed grows from the elongation of the plumule by breaking the layer of coleoptile and the root forms from the radicle by the breaking of the coleorhiza. The endosperm is present in the inner part of the seed around the embryo. This is the nutritive layer that provides nutrition for the growth of the embryo; the monocot seed possesses the aleurone layer which is the layer of protein that is present in between the endosperm and the outer covering of the seed.

Note: The example for the monocot seeds are the grains like rice, wheat, maize, barley etc., onion, banana, palm, ginger, coconut, garlic, bamboo, Lillie, tulips etc. All of these plants possess only one cotyledon or the scutellum in the seed of these plants.
