The storage product of chrysophytes is

Options

A. Oil and leucosin
B. Starch
C. Paramylum
D. Glycogen.

Answer

To answer the question regarding the storage product of chrysophytes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Chrysophytes**: Understand that chrysophytes are a group of algae commonly referred to as golden algae or golden-brown algae. They are primarily found in freshwater environments.

2. **Understand Their Characteristics**: Recognize that chrysophytes have a golden-brown color due to the presence of various photosynthetic pigments. This characteristic is important for their identification.

3. **Determine Storage Products**: The question specifically asks for the storage product of chrysophytes. We need to analyze the options provided:
- **Oil and Leucosin**: This is a combination of storage forms. Oil is a fatty acid, while leucosin is a polysaccharide (a carbohydrate).
- **Starch**: A common storage product in many plants, but not in chrysophytes.
- **Paramylum**: Another carbohydrate similar to starch, found in some protozoans and algae but not specifically in chrysophytes.
- **Glycogen**: A storage form of glucose found in animals, not in chrysophytes.

4. **Select the Correct Option**: Based on the analysis, the correct storage product of chrysophytes is **oil and leucosin**. This indicates that chrysophytes store their food primarily in the form of these substances.

5. **Conclusion**: Therefore, the answer to the question is that the storage product of chrysophytes is **oil and leucosin**.

### Final Answer:
The storage product of chrysophytes is **oil and leucosin**.
