Out of the seven names given above, find out haploid cells.

Options

A. I, III, IV, V
B. II, IV, VI, VII
C. I, II, III, V
D. II, III, V, VII

Answer

To determine which of the seven cells listed are haploid, we need to understand the ploidy level of each cell. Here’s a step-by-step analysis:

### Step 1: Understand the Definitions
- **Haploid (n)**: Cells that contain one set of chromosomes.
- **Diploid (2n)**: Cells that contain two sets of chromosomes.

### Step 2: Analyze Each Cell Type
1. **Antipodal Cell**:
- Part of the embryo sac, derived from the megaspore (which is haploid).
- **Ploidy**: Haploid (n).

2. **Fertilized Egg Cell**:
- Formed by the fusion of male and female gametes (both haploid), resulting in a diploid zygote.
- **Ploidy**: Diploid (2n).

3. **Synergid Cell**:
- Also part of the embryo sac, derived from the megaspore.
- **Ploidy**: Haploid (n).

4. **Polar Nucleus**:
- Found in the embryo sac, it consists of two haploid nuclei that have not yet fused.
- **Ploidy**: Haploid (n).

5. **Male Gamete**:
- Produced by meiosis, thus it has one set of chromosomes.
- **Ploidy**: Haploid (n).

6. **Nucellar Cell**:
- Part of the ovule, which is diploid.
- **Ploidy**: Diploid (2n).

7. **Integument Cell**:
- Also part of the ovule, which is diploid.
- **Ploidy**: Diploid (2n).

### Step 3: List the Haploid Cells
From the analysis:
- Antipodal Cell (I) - Haploid
- Synergid Cell (III) - Haploid
- Polar Nucleus (IV) - Haploid
- Male Gamete (V) - Haploid

### Conclusion
The haploid cells from the list provided are:
- I. Antipodal Cell
- III. Synergid Cell
- IV. Polar Nucleus
- V. Male Gamete

Thus, the answer is: **I, III, IV, V**.
