Megasporangium is also called as
Show Hint
In seed plants, the ovule is the megasporangium that produces megaspores, develops into the female gametophyte, and is protected by integuments.

The Correct Option is A
Solution and Explanation
Step 1: Understanding megasporangium.
A megasporangium is a structure in seed plants in which megaspores are produced. Megaspores develop into female gametophytes.
Step 2: Structure of ovule.
- The ovule contains the megasporangium (also called nucellus).
- It is covered by one or two protective integuments.
- The ovule is the functional unit that gives rise to the female gametophyte and ultimately the seed.
Step 3: Terminology.
- Megasporangium = Nucellus = Ovule (in gymnosperms and angiosperms context)
- Ovary is the structure that encloses one or more ovules.
- Embryosac is the female gametophyte inside the ovule.
- Seeds develop after fertilization inside the ovule.
Step 4: Conclusion.
Hence, megasporangium is also called an ovule because it contains the nucellus, megaspores, and later the female gametophyte.
