Seeds are called products of sexual reproduction because they

Options

A. are formed by fusion of gametes
B. give rise to new plants
C. can be stored for long time
D. are formed by fusion of pollen tubes

Answer

**Step-by-Step Solution:**

1. **Understanding Seeds in Reproduction:**
- Seeds are the result of the reproductive process in plants. They are formed after fertilization, which is a key aspect of sexual reproduction.

2. **Fusion of Gametes:**
- In sexual reproduction, male and female gametes fuse to form a zygote. In plants, the male gamete is contained within the pollen grain, while the female gamete is found in the ovule.
- The process begins when the pollen grain lands on the stigma of a flower, germinates, and forms a pollen tube that grows down to the ovule.

3. **Formation of the Embryo:**
- The pollen tube allows the male gamete to travel to the ovule, where it fuses with the egg cell (female gamete). This fusion results in the formation of a zygote, which then develops into an embryo.

4. **Development of Seeds:**
- The zygote develops into an embryo within the ovule, which eventually matures into a seed. The seed contains the embryo and is encased in a protective seed coat.

5. **Conclusion:**
- Therefore, seeds are called products of sexual reproduction because they are formed by the fusion of male and female gametes, leading to the development of a new plant.

**Final Answer:**
Seeds are called products of sexual reproduction because they are formed by the fusion of gametes.
