Question

(a) Explain the different ways apomictic seeds can develop. Give an example of each.

(b) Mention one advantage of apomictic seeds to farmers.

(c) Draw a labelled mature stage of a dicotyledonous embryo.

Answer 1

Different ways by which we can develop apomictic seeds include:

1. Formation of diploid egg i.e embryo without undergoing reduction division or fertilization e.g Asteraceae

2. Some nuclear cell divides surrounding the embryo sac divide continuously surrounding before protrude into embryo sac ultimately develop into embryo e.g Mango

(b) Advantage of apomitic seeds for farmers include reduce cost of seed purchase, They can keep the hybrid seeds once purchases for next season.

(c)
