Which of the following cells are located at chalazal end

Options

A. Oosphere or egg
B. Synergids
C. Central cell and egg apparatus
D. Antipodal cells.

Answer

To determine which cells are located at the chalazal end of the embryo sac, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of the Embryo Sac**:
- The embryo sac is a structure found in the ovule of flowering plants and contains several types of cells. It has two ends: the micropilar end and the chalazal end.

2. **Identifying the Micropilar End**:
- At the micropilar end, there are specific cells present. This end is characterized by the absence of integuments, allowing the entry of the pollen tube. The cells found here include one egg cell and two synergids.

3. **Identifying the Chalazal End**:
- The chalazal end is the opposite end of the micropilar end. Here, we need to identify the cells that are located at this end.

4. **Cells Present at the Chalazal End**:
- At the chalazal end of the embryo sac, there are three antipodal cells. These cells are haploid and are positioned at the chalazal end opposite to the micropilar end.

5. **Conclusion**:
- Therefore, the cells located at the chalazal end of the embryo sac are the three antipodal cells.

### Final Answer:
The cells located at the chalazal end are **three antipodal cells**.
