Androgenic haploidy makes use of cells
(a) Anther cells
(b) Callus cells
(c) Megaspore cells
(d) Microspore cells

Options

A. Anther cells
B. Callus cells
C. megaspore cells
D. Micropore cells.

Answer

To solve the question regarding which cells are used in androgenic haploidy, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Androgenic Haploidy**:
- Androgenic haploidy refers to the process where male gametophytes are used to produce haploid plants. This means that the resulting plants will have only one set of chromosomes (N).

2. **Identify the Process of Androgenesis**:
- In androgenesis, the development of pollen cells into male gametes is halted. This is crucial because we want to redirect the development of these cells into haploid plants instead of gametes.

3. **Determine the Cell Type Used**:
- The process primarily involves the culture of anthers, which are the parts of the flower that produce pollen. Therefore, anther cells are the ones utilized in this process.

4. **Evaluate the Options**:
- (a) Anther cells - Correct, as they are used in androgenic haploidy.
- (b) Callus cells - Incorrect, as they are not specifically used for androgenesis.
- (c) Megaspore cells - Incorrect, as they are related to female gametophyte development.
- (d) Microspore cells - Incorrect, as they are not directly used in the process of androgenesis.

5. **Conclusion**:
- Based on the understanding of androgenic haploidy and the evaluation of the options, the correct answer is (a) Anther cells.

### Final Answer:
**(a) Anther cells**
