Answer 1

Explanation:

6).

Three main types of endosperm development in flowering plants are: (i) Nuclear type (ii) Cellular type and (iii) Helobial type! The formation of endosperm is initiated by mitotic divisions of the primary endosperm nucleus (3N). The formation of endosperm occurs usually prior to the zygotic division.

7). Non-albuminous seeds have no residual endosperm as it is completely consumed during embryo development (eg., pea, groundnut). Albuminous seeds retain a part of endosperm as it is not completely used up. during embryo development (e.g. wheat, maize, barley, caster, sunflower).
