Write briefly the role of pollination in an angiosperm .

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Pollination**: Pollination is the process of transferring pollen grains from the male part of a flower (anther) to the female part (stigma). This is a crucial step in the reproductive cycle of angiosperms (flowering plants).

2. **Types of Pollination**:
- **Self-Pollination**: This occurs in bisexual flowers where the pollen from the anther of the same flower lands on its own stigma. This leads to fertilization without the need for pollen from another flower.
- **Cross-Pollination**: This involves the transfer of pollen from the anther of one flower to the stigma of another flower. It can occur between different flowers of the same species or different species.
