Nutrition in protists is

Options

A. Holophytic
B. Holozoic
C. Saprozoic
D. All of these

Answer

### Step-by-Step Solution:

1. **Understanding Protists**:
- Protists are a diverse group of organisms that can exhibit various nutritional modes. They can resemble organisms from the kingdoms Plantae, Fungi, and Animalia.

2. **Types of Nutrition in Protists**:
- **Autotrophic Nutrition**: Some protists have chloroplasts and can perform photosynthesis, making them autotrophs. They produce their own food and do not rely on other organisms.
- **Heterotrophic Nutrition**: Other protists depend on other organisms for food. This can be further divided into:
- **Holozoic Nutrition**: This involves the ingestion of whole organisms or large organic matter. Protists that exhibit this type of nutrition consume other organisms.
- **Saprozoic Nutrition**: This type involves the absorption of dissolved organic matter from the environment. However, it is not commonly observed in protists.
- **Parasitic Nutrition**: Some protists can also be parasitic, deriving nutrients from a host organism.

3. **Identifying the Correct Answer**:
- The question asks about the types of nutrition in protists.
- The options provided are:
- Holophytic
- Holozoic
- Saprozoic
- All of these
- Holophytic nutrition is not applicable to protists as they cannot ingest whole plant materials. Saprozoic nutrition is also not commonly observed in protists. Therefore, the most relevant type of nutrition that protists exhibit is **Holozoic** nutrition.

4. **Conclusion**:
- Based on the analysis, the correct answer to the question "Nutrition in protists is" is **Holozoic**.
