Multicellular eukaryotic organisms with holophytic mode of nutrition belong to how many kingdoms in Whittaker system ?

Options

A. One
B. Two
C. Three
D. Five

Answer

To determine how many kingdoms in the Whittaker system include multicellular eukaryotic organisms with a holophytic mode of nutrition, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Whittaker System**: The Whittaker system classifies living organisms into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.

2. **Identify Characteristics of Each Kingdom**:
- **Monera**: Unicellular and prokaryotic organisms (e.g., bacteria).
- **Protista**: Mostly unicellular eukaryotic organisms (e.g., protozoa, some algae).
- **Fungi**: Multicellular eukaryotic organisms (e.g., mushrooms, molds).
- **Plantae**: Multicellular eukaryotic organisms that are autotrophic (e.g., plants).
- **Animalia**: Multicellular eukaryotic organisms that are heterotrophic (e.g., animals).

3. **Focus on Multicellular Eukaryotic Organisms**: The question specifically asks about multicellular eukaryotic organisms. Therefore, we will focus on the kingdoms Fungi, Plantae, and Animalia.

4. **Define Holophytic Nutrition**: Holophytic nutrition refers to the ability of an organism to produce its own food through photosynthesis, which is characteristic of autotrophic organisms.

5. **Identify the Relevant Kingdoms**:
- **Plantae**: Organisms in this kingdom are autotrophic and perform photosynthesis, thus fitting the holophytic nutrition category.
- **Fungi**: These organisms do not perform photosynthesis; they are heterotrophic.
- **Animalia**: These organisms are also heterotrophic and do not perform photosynthesis.

6. **Conclusion**: Based on the characteristics of the kingdoms, only the Plantae kingdom includes multicellular eukaryotic organisms with holophytic nutrition. Therefore, the answer to the question is that there is **1 kingdom** (Plantae) that fits the criteria.

### Final Answer:
**1 Kingdom (Plantae)**
