Why cannot fertilisation take place in flowers if pollination does not occur?

Explanation

### Step-by-Step Solution:

1. **Define Pollination**:
- Pollination is the process of transferring pollen grains from the anther (the male part of the flower) to the stigma (the female part of the flower) of the same or another flower.

2. **Define Fertilization**:
- Fertilization is the process where the male gamete (sperm) and the female gamete (egg) fuse together to form a zygote, which is the first step in the development of a new organism.
