Which of the following is the correct sequence of events of sexual reproduction in a flower?

Options

A. Pollination, fertilization, seedling, embryo
B. Seedling, embryo, fertilization, pollination
C. Pollination, fertilization, embryo, seedling
D. Embryo, seedling, pollination, fertilization

Answer

To determine the correct sequence of events in sexual reproduction in a flower, we can break down the process into several key steps:

### Step-by-Step Solution:

1. **Pollination**: The first step in the sexual reproduction of flowers is pollination. This is the process where pollen grains from the anther (male part) are transferred to the stigma (female part) of the flower. This can occur through various agents such as wind, water, or pollinators like bees.

2. **Germination**: After successful pollination, the pollen grain germinates on the stigma. This means that the pollen grain begins to grow a pollen tube down through the style towards the ovary.

3. **Fertilization**: Once the pollen tube reaches the ovule in the ovary, fertilization occurs. This is when the male gamete (from the pollen) fuses with the female gamete (in the ovule) to form a zygote.

4. **Embryo Development**: Following fertilization, the zygote develops into an embryo. This is a crucial stage where the initial development of the new plant begins.

5. **Seedling Formation**: Finally, the embryo develops into a seedling. The seed will eventually germinate under suitable conditions to grow into a new plant.

### Correct Sequence:
- **Pollination → Germination → Fertilization → Embryo → Seedling**
