What is pollination? How is self-pollination different from cross pollination.

Explanation

### Step-by-Step Solution:

1. **Definition of Pollination**:
- Pollination is the process of transferring pollen grains, which contain male gametes, from the anther (the male part of a flower) to the stigma (the female part of a flower). This transfer is essential for fertilization to occur in flowering plants.

2. **Self-Pollination**:
- Self-pollination occurs when pollen grains are transferred from the anther to the stigma of the same flower. Alternatively, it can also happen between different flowers on the same plant. In both cases, the anther and stigma involved are from the same plant.
