Pollen kitt is a yellow coloured, sticky layer present outside the pollen grains, which serves the purpose of

Options

A. Protection against UV rays
B. Insect attractant
C. Pollen germination
D. More than one option is correct

Answer

### Step-by-Step Solution:

1. **Definition of Pollen Kit**: The pollen kit is a yellow-colored, sticky layer that is found on the outer surface of pollen grains.

2. **Composition**: This sticky layer is primarily composed of lipids and carotenoids, which contribute to its yellow color and sticky texture.

3. **Functions of Pollen Kit**:
- **Protection**: The pollen kit serves as a protective envelope for the pollen grain, shielding it from harmful UV rays and environmental factors.
- **Insect Attractant**: The sticky nature of the pollen kit helps in attracting insects, which are essential for the process of pollination. Insect-pollinated plants often have pollen grains that are sticky to ensure that insects can transport them effectively.
- **Facilitation of Pollination**: The pollen kit aids in the transfer of pollen grains from the anthers (male part of the flower) to the stigma (female part of the flower), facilitating the process of fertilization.

4. **Conclusion**: Therefore, the pollen kit serves multiple purposes, including protection against UV rays, acting as an insect attractant, and assisting in the process of pollination. Hence, more than one option regarding its purpose is correct.
