The megasporangium of the angiosperms on maturation gives rise to

Options

A. (a) fruit
B. (b) seeds
C. (c) embryo
D. (d) cotyledons

Answer

To answer the question "The megasporangium of the angiosperms on maturation gives rise to," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure**: The megasporangium is located within the ovary of angiosperms and is part of the female reproductive system. It is also known as the ovule.

2. **Understand the Function**: The primary function of the megasporangium (ovule) is to develop into the female gamete, which is the egg cell. This egg cell is haploid and is crucial for fertilization.

3. **Maturation Process**: Upon maturation, the megasporangium undergoes a process where it forms an embryo sac. The embryo sac contains the haploid egg cell.

4. **Post-Fertilization Development**: After fertilization occurs, the ovary develops into a fruit, while the ovule (megasporangium) develops into a seed.

5. **Evaluate the Options**:
- **Option A: Fruit** - This is incorrect because the fruit develops from the ovary, not directly from the megasporangium.
- **Option B: Seeds** - This is correct as the ovule (megasporangium) develops into seeds after fertilization.
- **Option C: Embryo** - This is an intermediate stage in the development of the seed and not a direct product of the megasporangium.
- **Option D: Cotyledons** - These are parts of the seed and not derived directly from the megasporangium.

6. **Conclusion**: The most appropriate answer is **Option B: Seeds**.
