Answer

To identify the ploidy of the various parts of a flowering plant, we will analyze each part step by step:

1. **Ovary**: The ovary is part of the female reproductive structure in flowering plants. It contains ovules, which are the structures that develop into seeds after fertilization. The ovary is diploid (2n) because it contains two sets of chromosomes, one from each parent.

**Hint**: Remember that the ovary is part of the plant's reproductive system and contains ovules, which are diploid.

2. **Anther**: The anther is part of the male reproductive structure (stamen) and is responsible for producing pollen grains. Since the anther produces pollen, it is also diploid (2n) because it contains two sets of chromosomes.

**Hint**: The anther produces pollen, which is formed from diploid cells undergoing meiosis.

3. **Egg**: The egg cell is the female gamete produced in the ovule. It is haploid (n), meaning it contains only one set of chromosomes.

**Hint**: The egg is a gamete, so it will have half the number of chromosomes compared to the diploid structures.

4. **Pollen**: Pollen grains are the male gametes produced by the anther. Like the egg, pollen is haploid (n), containing one set of chromosomes.

**Hint**: Pollen is produced through meiosis from diploid cells in the anther, resulting in haploid gametes.

5. **Male Gamete**: The male gamete is the sperm cell that is found in the pollen. It is also haploid (n), as it is derived from the pollen grain.

**Hint**: The male gamete is the same as the pollen grain in terms of ploidy, as both are haploid.

6. **Zygote**: The zygote is formed when the male gamete (sperm) fertilizes the female gamete (egg). The zygote is diploid (2n) because it contains two sets of chromosomes, one from each parent.

**Hint**: The zygote is the result of fertilization, combining the haploid sets from both the egg and the sperm, resulting in a diploid cell.

### Summary of Ploidy:
- **Ovary**: 2n (diploid)
- **Anther**: 2n (diploid)
- **Egg**: n (haploid)
- **Pollen**: n (haploid)
- **Male Gamete**: n (haploid)
- **Zygote**: 2n (diploid)

### Final Answer:
- Ovary: 2n
- Anther: 2n
- Egg: n
- Pollen: n
- Male Gamete: n
- Zygote: 2n
