How many microsporangia are found in each lobe of anther ?

Options

A. One microporangia
B. Two microporangia
C. Three microporangia
D. Four microporangia

Answer

To determine how many microsporangia are found in each lobe of an anther, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of the Anther**:
- The anther is typically a bilobed structure, meaning it has two lobes.

2. **Identifying the Components of Each Lobe**:
- Each lobe of the anther contains two structures called "thecae" or "thikas".

3. **Counting the Microsporangia**:
- Each theca in a lobe contains microsporangia, which are the sites where pollen grains develop.
- In a typical angiospermic anther, each lobe has two thecae.

4. **Calculating the Total Microsporangia per Lobe**:
- Since each lobe has two thecae and each theca contains one microsporangium, we can conclude:
- 1 lobe = 2 thecae = 2 microsporangia.

5. **Final Answer**:
- Therefore, there are **2 microsporangia in each lobe of the anther**.

### Summary:
In conclusion, each lobe of the anther contains **2 microsporangia**.
