Answer

To answer the question "The anther is a four-sided structure consisting of:", we can break down the information step by step.

### Step-by-Step Solution:

1. **Understanding the Anther**:
- The anther is part of the male reproductive structure in flowering plants, specifically a component of the stamen.

2. **Structure of the Stamen**:
- The stamen consists of two main parts: the filament (the long stalk) and the anther (the two-lobed structure at the tip).

3. **Description of the Anther**:
- The anther is described as a four-sided structure, which means it has four distinct corners.

4. **Components of the Anther**:
- Each lobe of the anther contains two sac-like structures called microsporangia.

5. **Total Count of Microsporangia**:
- Since there are two lobes and each lobe has two microsporangia, the total number of microsporangia in the anther is four (2 microsporangia per lobe × 2 lobes = 4 microsporangia).

6. **Function of Microsporangia**:
- The microsporangia are responsible for producing pollen, which is essential for the process of pollination.

7. **Additional Structures**:
- The anther also has a connective tissue that connects the two lobes and contains conducting strands.

### Final Answer:
The anther is a four-sided structure consisting of four microsporangia located at the corners of the lobes.
