The correct sequence of reproductive stages seen in flowering plants is

Options

A. gametes, zygote, embryo, seedling
B. zygote, gametes, embryo, seedling
C. seedling, embryo, zygote, gametes
D. gametes, embryo, zygote, seedling

Explanation

**Step-by-Step Solution:**

1. **Formation of Gametes**: The reproductive process in flowering plants begins with the formation of male and female gametes. Male gametes are produced in the anthers, while female gametes are produced in the ovules.

2. **Pollination**: The next stage is pollination, where the pollen grains (which contain the male gametes) are transferred to the stigma of the flower. This can occur through various agents like wind, water, or animals.

3. **Fertilization**: Once the pollen grain lands on the stigma, it germinates and forms a pollen tube that grows down into the ovary. The male gamete travels through this pollen tube to fuse with the female gamete in the ovule. This fusion is known as fertilization, resulting in the formation of a zygote.

4. **Development of Zygote**: After fertilization, the zygote undergoes mitosis and develops into an embryo. This is a crucial stage where the zygote transforms into a multicellular structure.

5. **Formation of Seedling**: The embryo eventually develops into a seed, which, when conditions are favorable, germinates to produce a seedling. This marks the beginning of a new plant.

6. **Correct Sequence**: The correct sequence of reproductive stages in flowering plants is:
- Formation of gametes
- Pollination
- Fertilization (formation of zygote)
- Development of embryo
- Formation of seedling

**Final Answer**: The correct sequence of reproductive stages seen in flowering plants is: Formation of gametes → Pollination → Fertilization → Development of embryo → Formation of seedling.
