Which of the following are eukaryotic multicellular organisms having cells with cell wall and show heterotrophic mode of nutrition?

Options

A. Plantae
B. Animalia
C. Protista
D. Fungi

Answer

To solve the question, we need to identify which organisms are eukaryotic, multicellular, have a cell wall, and exhibit heterotrophic nutrition. Here’s a step-by-step breakdown:

### Step 1: Understand the Terms
- **Eukaryotic**: Organisms whose cells have a nucleus enclosed within membranes.
- **Multicellular**: Organisms made up of more than one cell.
- **Cell Wall**: A rigid layer that surrounds the cell membrane in certain organisms, providing structure and support.
- **Heterotrophic Nutrition**: Organisms that cannot produce their own food and instead obtain nutrients by consuming other organisms.

### Step 2: Analyze the Options
We need to evaluate the options provided in the question based on the criteria above.

1. **Plants**:
- Eukaryotic? Yes
- Multicellular? Yes
- Cell Wall? Yes (made of cellulose)
- Heterotrophic? No (they are autotrophic as they produce their own food through photosynthesis)

2. **Animals**:
- Eukaryotic? Yes
- Multicellular? Yes
- Cell Wall? No (animals do not have a cell wall)
- Heterotrophic? Yes (they obtain food by consuming other organisms)

3. **Protista**:
- Eukaryotic? Yes
- Multicellular? Some are, but many are unicellular.
- Cell Wall? Some have it, but many do not.
- Heterotrophic? Yes (some are heterotrophic)

4. **Fungi**:
- Eukaryotic? Yes
- Multicellular? Yes (most fungi are multicellular, like molds and mushrooms)
- Cell Wall? Yes (made of chitin)
- Heterotrophic? Yes (they absorb nutrients from other organisms)

### Step 3: Conclusion
Based on the analysis:
- **Fungi** meet all the criteria: they are eukaryotic, multicellular, have a cell wall, and exhibit heterotrophic nutrition.

Thus, the correct answer is **Fungi**.
