How many given structures are haploid ?
Ovary, anther, egg, pollen, male, gamete, zygote

Options

A. 3
B. 4
C. 5
D. 6

Answer

To determine how many of the given structures are haploid, we need to analyze each structure one by one:

1. **Ovary**: The ovary is part of the female reproductive organ in flowering plants and is a part of the sporophyte generation. Therefore, it is **diploid**.

2. **Anther**: The anther is part of the male reproductive organ in flowering plants and is also part of the sporophyte generation. Hence, it is **diploid**.

3. **Egg**: The egg is the female gamete produced by the ovule in the ovary. Since gametes are formed through meiosis, the egg is **haploid**.

4. **Pollen**: Pollen grains are the male gametophytes that produce male gametes (sperm). Each pollen grain is formed from the microspore and is **haploid**.

5. **Male Gamete**: The male gamete is produced from the pollen grain and is also **haploid**.

6. **Zygote**: The zygote is formed when the male gamete fertilizes the female gamete (egg). The zygote is the first cell of the new sporophyte generation, making it **diploid**.

Now, let's summarize the haploid structures identified:
- Egg (haploid)
- Pollen (haploid)
- Male Gamete (haploid)

Thus, there are **three structures that are haploid**.

### Final Answer:
The number of haploid structures is **3** (Egg, Pollen, Male Gamete).
