Differentiate between microsprogenesis and magasporogenesis. Which type of cell division occur during these events ? Name the structure formed at the end of these two events

Explanation

(i) Differences between microsporogenesis and megasporogenesis.
(ii) Type of cell division during micro-sporogenesis and megasporogensis : meiosis.
(ii) Sturcture formed :

(a) Due to microsporogenesis. Microspores (pollen grains) are formed which lead to development of male gametophyte.
(b) Due to megasporogenesis. Megaspores are formed. Out of them one megaspore leads to development of female gametophyte (embryo sac).
