Question

The ovule of angiosperm is technically known as

• A. Megaspore
• B. Megasporangium
• C. Megasporophyl
• D. Megaspore mother cell

Answer 1

The Correct Option is B

The ovule is the structure within the ovary of a flower that contains the female reproductive cells. It consists of various parts, including the megasporangium, which is the structure that houses the megaspore mother cell.

The megasporangium is responsible for producing and protecting the megaspore mother cell. The megaspore mother cell then undergoes meiosis, resulting in the formation of megaspores.

Therefore, the correct answer is (B) Megasporangium.

Answer 2

The correct answer is:

Option 2: Megasporangium

Explanation:

In angiosperms (flowering plants), the ovule is technically known as the megasporangium. It is the structure within which the female gametophyte (embryo sac) develops, and it contains the megaspore mother cell that undergoes meiosis to form the megaspore.

The megasporangium is the organ in which the ovule develops and contains the megaspore mother cell.

The other options are incorrect because:

Megaspore (Option 1) refers to the spore produced by the megasporangium that will develop into the female gametophyte (embryo sac).

Megasporophyll (Option 3) refers to a leaf or modified leaf that bears the megasporangium, typically seen in gymnosperms, not angiosperms.

Megaspore mother cell (Option 4) is the cell that undergoes meiosis to form the megaspore, but it is not technically the ovule.

Thus, the ovule of an angiosperm is technically known as the megasporangium.
