Question

Are corn seeds endospermic?

Answer 1

Corn seeds:

1. Corn seed is monocotyledonous. They have one large, shield-shaped cotyledon called ‘scutellum’ that is located towards the side of the embryo axis.
2. In endospermic seeds, the endosperm is located outside cotyledons, which are leafy or tiny.
3. Corn seeds are endospermic. Endosperm stores a large amount of food and provides nourishment to the embryo.
4. The endosperm is produced by triple fusion. After zygote formation, the second male gamete fuses with two polar nuclei that are located in the central cell of the embryo sac.
5. After triple fusion, the central cell becomes the primary endosperm cell and eventually develops into endosperm.
