Vedclass · Answer

(B) In angiosperms,ovules are classified based on the amount and development of the nucellus.$1$. Crassinucellate ovules are those in which the megaspore mother cell is formed from a hypodermal archesporial cell that divides to form a primary parietal cell and a primary sporogenous cell.$2$. This results in a massive or well-developed nucellus because the parietal tissue is formed.$3$. In contrast,tenuinucellate ovules have a very small or poorly developed nucellus where the archesporial cell functions directly as the megaspore mother cell.
