Answer:A

Explanation:

Answer 2

Answer:

(B) Cotyledons and endosperm

Explanation:

Non-endospermic Seeds or Ex-albuminous Seeds

Seeds which usually store food materials in their cotyledons are called non-endospermic or ex-albuminous seeds.

Example: Gram, Pea, Bean, Almond, Groundnut

Endospermic Seeds or Albuminous Seeds

Seeds which usually store food materials in their endosperm are called endospermic or albuminous seeds.

Example: Castor, Maize, Wheat, Barley, Grasses

Cotyledons

Cotyledons is a seed leaf within the embryo of a seed. They helps in supplying the nutrition to a plant where embryo needs to germinate and become a photosynthetic organism.

Endosperm

The endosperm is a type of tissue which is produced inside the seeds of most of the flowering plants which follows double fertilization. It is usually triploid in most species and may be auxin-driven. It helps in surrounding the embryo and provides nutrition in the form of starch, though it can also contain oils and protein.
