An anther with malfunctioning tapetum often fails to produce viable male gametophytes . Give one reason

Explanation

**Step-by-Step Solution:**

1. **Understanding the Anther and Tapetum**: The anther is a part of the stamen in flowering plants, responsible for producing pollen grains, which contain male gametophytes. The tapetum is a layer of cells within the anther that plays a crucial role in nourishing the developing pollen grains.

2. **Function of the Tapetum**: The primary function of the tapetum is to provide essential nutrients and support to the developing pollen grains (microspores). This nourishment is vital for the proper development and maturation of the pollen grains.

3. **Impact of Malfunctioning Tapetum**: If the tapetum is malfunctioning, it cannot perform its role effectively. This means it will not supply the necessary nutrients and support that the developing pollen grains require for their growth.
