The male gametes in a flower and in a human are produced sperm in:

Options

A. stigma and ovary
B. anther and style
C. ovary and testes
D. radicle

Answer

**Step-by-Step Solution:**

1. **Understanding Male Gametes**: Male gametes are the reproductive cells that participate in fertilization. In flowering plants, these are represented by pollen grains, while in humans, they are represented by sperm cells.

2. **Identifying the Source in Flowers**: In flowering plants, male gametes are produced in the anther, which is part of the stamen (the male reproductive organ of the flower). The anther contains pollen grains, which carry the male gametes.

3. **Identifying the Source in Humans**: In humans, male gametes (sperm) are produced in the testes. The testes are the male reproductive organs responsible for the production of sperm and hormones.

4. **Analyzing the Options**: The question provides multiple options to identify where male gametes are produced:
- Option 1: Stigma and ovary (female structures)
- Option 2: Anther and testes (male structures)
- Option 3: Ovaries and testes (ovaries are female structures)
- Option 4: Radicals (not related to gamete production)

5. **Selecting the Correct Option**: Based on the analysis, the correct option is the second one: "Anther and testes," as both are responsible for the production of male gametes (pollen grains in flowers and sperm in humans).

**Final Answer**: The male gametes in a flower and in a human are produced in the anther and testes, respectively.
