The innermost wall layer of anther

Options

A. is nutritive in function
B. helps in dehiscence of anther
C. is haploid and protective in function
D. forms microspores

Answer

**Step-by-Step Solution:**

1. **Identify the Anther Structure**: The anther is a key part of the stamen in flowering plants, responsible for producing pollen grains, which contain male gametes.

2. **Understand the Layers of the Anther**: The anther consists of several layers, including the outer epidermis, the middle layer, the innermost layer called the tapetum, and the sporogenous tissue.

3. **Focus on the Innermost Layer**: The innermost wall layer of the anther is known as the tapetum.

4. **Function of the Tapetum**: The primary function of the tapetum is to provide nourishment to the developing microspores (pollen grains) within the sporogenous tissue. It plays a crucial role in the growth and development of these microspores.

5. **Additional Functions**: Besides its nutritive role, the tapetum also helps in the formation of the pollen grains and is involved in the overall development of the anther.

6. **Conclusion**: Therefore, the innermost wall layer of the anther is the tapetum, which is nutritive in function and essential for pollen development.
