Where the pollen grains are formed in a plant?

Answer

**Step-by-Step Text Solution:**

1. **Identify the Male Reproductive Organ**: In flowering plants, the male reproductive organ is known as the Androsium.

2. **Structure of Androsium**: The Androsium is made up of a group of structures called stamens. Each stamen consists of two main parts: the filament and the anther.

3. **Parts of the Stamen**:
- **Filament**: This is the long, cylindrical stalk that supports the anther.
- **Anther**: This is the terminal part of the stamen, which is usually bilobed (having two lobes).

4. **Anther Structure**: A typical angiospermic anther is bilobed and consists of four microsporangia (pollen sacs) located at the corners of the anther, with two in each lobe.

5. **Microsporangia**: Each lobe of the anther contains two microsporangia, making a total of four microsporangia in the anther.

6. **Formation of Pollen Grains**: The pollen grains, which are the male gametes, are formed in these microsporangia. The microsporangia develop into pollen sacs, where the pollen grains mature.

7. **Conclusion**: Therefore, pollen grains are formed in the pollen sacs located within the microsporangia of the anther in the male reproductive organ of flowering plants.
