Chemically the pollenkit is made up of

Options

A. proteins
B. lipids
C. carbohydrates
D. sporopollenin

Answer

### Step-by-Step Solution:

1. **Understanding Pollen Kit**:
- The pollen kit is a sticky surface found on pollen grains. It plays a crucial role in the process of pollination by allowing pollen grains to adhere to pollinators like insects and birds.

2. **Chemical Composition of Pollen Kit**:
- The pollen kit is primarily composed of lipids. These lipids contribute to its sticky nature, which is essential for the pollen to attach to pollinators.

3. **Comparison with Other Components**:
- The outer layer of the pollen grain is called the exine, which is made of sporopollenin, a tough organic compound. The inner layer, known as the intine, is made up of cellulose and pectin.
- The pollen grain itself contains two types of cells: a vegetative cell and a generative cell.

4. **Conclusion**:
- Therefore, the correct answer to the question "Chemically, the pollen kit is made up of" is that it is made up of lipids.
