Basal foot layer and tectum are associated with which of the following structures?

Options

A. Microspore
B. Embryo sac
C. Seed
D. Megaspore

Answer

To solve the question regarding the association of the basal foot layer and tectum, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Basal Foot Layer**: This is a layer in the pollen grain that acts as a filter membrane, allowing selective entry of substances.
- **Tectum**: This is a protective layer that forms a roof-like structure over the pollen grain.

2. **Analyze the Options**:
- **Microspores**: These are the male gametes produced in plants and are found within the pollen grains.
- **Embryo Sac**: This is part of the female reproductive structure in flowering plants and does not contain the basal foot layer or tectum.
- **Megaspores**: These are also female reproductive structures and are not associated with the basal foot layer or tectum.
- **Others**: Consider if there are any other options provided in the original question.

3. **Relate the Structures**:
- Since the basal foot layer and tectum are components of the pollen grain, they are directly associated with microspores, which are the male gametes formed within the pollen.

4. **Conclusion**:
- Based on the analysis, the basal foot layer and tectum are associated with **microspores**.

### Final Answer:
The basal foot layer and tectum are associated with **microspores**.
