Megasporangium is equivalent to

Options

A. Nucellus
B. Ovule
C. Embryo sac
D. Fruit

Explanation

To solve the question "Megasporangium is equivalent to," we can follow these steps:

### Step 1: Understand the Definition
The term "megasporangium" refers to a structure in plants that is responsible for producing megaspores, which ultimately develop into female gametophytes.

**Hint:** Look for the role of megasporangium in plant reproduction.

### Step 2: Identify the Context
In angiosperms (flowering plants), the megasporangium is specifically involved in the formation of the ovule. The ovule is the structure that contains the female gametophyte and is crucial for fertilization.

**Hint:** Consider how the megasporangium functions within the reproductive structures of angiosperms.

### Step 3: Relate to Angiosperms
In angiosperms, the megasporangium develops into the ovule. The ovule is the part of the plant that will eventually develop into a seed after fertilization.

**Hint:** Think about the relationship between the megasporangium and the ovule in the lifecycle of flowering plants.

### Step 4: Conclusion
Based on the understanding that the megasporangium is equivalent to the ovule in angiospermic plants, we can conclude that the answer to the question is:

**Answer:** Megasporangium is equivalent to the ovule.

### Summary
- The megasporangium produces megaspores.
- In angiosperms, it develops into the ovule.
- The ovule contains the female gametophyte and is essential for seed development.
