Question

Do maize and pea have perispermic seeds?

Answer 1

Perispermic seeds :

1. The remnants of the nucellus in seeds are perisperm, and it is a diploid tissue.
2. Post the process of fertilization, the nucellus develops into the perisperm.
3. It offers nutrition to the developing embryo and is produced at the micropylar terminal of the ovule.
4. The seeds, which comprise perisperm are known as Perispermic seeds, for example, Beta vulgaris and Piper nigrum.

Endospermic seeds:

1. Maize and peas do not possess perispermic seeds, they possess endospermic seeds.
2. Endosperm acts as the food-storing tissue of a seed. It is generated as a result of double fertilization in angiosperms.
3. In some dicot and the majority of monocot seeds, the food reserve remains in the endosperm, they are called albuminous or endospermic seeds.
4. For example, castor bean, maize, peas, rubber, etc.
5. The endospermic seeds are generally soft in comparison to perispermic seeds.
