Chose-pollination requires abiote or biotic agent.

Answer

### Step-by-Step Solution:

1. **Understanding Cross-Pollination**:
- Cross-pollination is the process where pollen from the male part (anther) of one flower fertilizes the ovule of another flower of the same species, but from a different plant. This is essential for genetic diversity in plants.

2. **Identifying Pollination Agents**:
- Pollination can occur through two main types of agents: abiotic and biotic.

3. **Abiotic Agents**:
- Abiotic agents are non-living factors that assist in the transfer of pollen. The primary abiotic agents include:
- **Wind**: Many plants, especially grasses and some trees, rely on wind to carry their pollen from one flower to another.
- **Water**: In some aquatic plants, water can facilitate the movement of pollen.

4. **Biotic Agents**:
- Biotic agents are living organisms that help in the transfer of pollen. These include:
- **Insects**: Bees, butterflies, and other insects are crucial for pollination as they visit flowers for nectar and inadvertently transfer pollen.
- **Birds**: Certain species of birds, like hummingbirds, are also important pollinators.
- **Bats**: In some regions, bats are significant pollinators, especially for nocturnal flowers.
- **Other Animals**: Snails and even humans can play a role in pollination.

5. **Conclusion**:
- Both abiotic and biotic agents are essential for cross-pollination. Without these agents, the process of fertilization would be hindered, affecting the reproduction and genetic diversity of flowering plants.
