What could be the number of cells in a typical angiosperm embryo sac?

Options

A. 5
B. 6
C. 7
D. 8

Explanation

To determine the number of cells in a typical angiosperm embryo sac, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Embryo Sac**: The embryo sac is an elongated structure with two ends: the chalazal end and the micropylar end.

2. **Identify the Cells at the Chalazal End**: At the chalazal end, there are three cells known as antipodal cells. So, we have:
- Antipodal cells = 3

3. **Identify the Cells at the Micropylar End**: At the micropylar end, there are two synergids and one egg cell. Thus, we have:
- Synergids = 2
- Egg cell = 1

4. **Identify the Central Cell**: In addition to the above cells, there is one central cell present in the embryo sac. So, we have:
- Central cell = 1

5. **Total Cell Count**: Now, we can add up all the cells:
- Total cells = Antipodal cells + Synergids + Egg cell + Central cell
- Total cells = 3 (antipodal) + 2 (synergids) + 1 (egg) + 1 (central) = 7

### Conclusion:
The total number of cells in a typical angiosperm embryo sac is **7**.
