Question

1. Point out the odd one A) nucellus b] embryo sac d) micropyle d) pollen grain ​

Answer 1

Answer:

Micropyle is a small opening on the surface of an ovule.Embryo sac is the structure within a plant ovule that contains the egg cell.Nucellus is the central part of an ovule, containing the embryo sac.Pollen grain is a microscopic body that contains the male reproductive cell of a plant.As all other structures are part of the ovule apart from the Pollen grain, therefore it is an odd one out. Hence, option D is correct.
