Q. Megasporangium is equivalent to :
(a) Fruit
(b) Nucellus
(c) Ovule
(d) Embryo sac
Solution :
Correct option : C An Ovule (megasporangium) generally has a single embryo sac formed from a megaspore through reduction division. It is a small structure attached to the placenta by means of a stalk called funicle. Ovule→Megaspore Mother Cell (MMC) by meiosis→Megaspore. Each has one or two protective envelopes called integuments. The nucleus is a mass of cells enclosed with the integuments. Fruits develop from the ovary of a flower, other floral parts degenerate and fall off. So, the correct answer is ‘Ovule’.
