Question

Which one of the following is not associated with megasporangium?

• A. Funicle
• B. Integument
• C. Generative cell
• D. Micropyle

Answer 1

The Correct Option is C

The megasporangium, also known as the ovule in seed plants, is surrounded by the integuments, has a micropyle (small opening for pollen entry), and is connected to the ovary wall via the funicle. The generative cell, however, is associated with pollen grain development and not with the megasporangium.

Answer 2

Megasporangium, also known as the ovule, is the part of the plant that contains the female gametophyte and produces the megaspore, which gives rise to the egg cell.

• Funicle (1): The funicle is the stalk of the ovule that connects it to the placenta of the plant.
• Integument (2): The integument is a layer of tissue surrounding the ovule and eventually forms the seed coat.
• Micropyle (4): The micropyle is a small opening in the integument of the ovule, through which the pollen tube enters during fertilization.

The generative cell (3) is part of the male gametophyte (pollen grain), not the megasporangium (female side). It divides to form the two sperm cells that fertilize the egg and the central cell in the ovule.
