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

Options

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

Explanation

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

### Step-by-Step Solution:

1. **Pollination**: The first event in sexual reproduction in a flower is pollination. This is the process where pollen grains are transferred from the anther (the male part of the flower) to the stigma (the female part of the flower). This transfer can occur within the same flower, between flowers on the same plant, or between flowers on different plants.

2. **Pollen Tube Formation**: After pollination, once the pollen grain lands on the stigma, it germinates and forms a pollen tube. This pollen tube grows down the style towards the ovary of the flower.

3. **Fertilization**: The next step is fertilization. The pollen tube carries the male gamete (sperm) to the ovary, where it fuses with the female gamete (egg cell). This fusion of male and female gametes results in the formation of a zygote.

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

5. **Seedling Formation**: Finally, the embryo develops into a seedling. This seedling will eventually grow into a new plant.

### Correct Sequence:
The correct sequence of events in sexual reproduction in a flower is:
1. Pollination
2. Fertilization
3. Formation of the embryo
4. Development of seedlings

Based on the options provided, the correct answer is **Option C**: Pollination followed by fertilization, then the embryo is formed, and lastly, the seedlings come out.
