What are two kinds of pollination ? Which one is more beneficial for plants ?

Explanation

**Step-by-Step Solution:**

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

2. **Types of Pollination**:
- **Self-Pollination**: This occurs when pollen is transferred from the anther to the stigma of the same flower or to another flower on the same plant. In this case, the genetic material comes from one plant.
- **Cross-Pollination**: This occurs when pollen is transferred from the anther of one flower to the stigma of a flower on a different plant of the same species. Here, the genetic material comes from two different plants.
