The heterotrophic, eukaryotic, multicellular organism without cell wall is included in the kingdom

Options

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

Answer

To determine the kingdom to which heterotrophic, eukaryotic, multicellular organisms without a cell wall belong, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Characteristics**:
- The organism is heterotrophic, meaning it cannot produce its own food and relies on other organisms for nutrition.
- It is eukaryotic, indicating that its cells have a nucleus and other membrane-bound organelles.
- It is multicellular, meaning it is composed of multiple cells.
- It lacks a cell wall, which is a significant characteristic that differentiates it from some other kingdoms.

2. **Evaluate the Options**:
- **Kingdom Fungi**: Organisms in this kingdom are typically heterotrophic and can be multicellular (like molds and mushrooms). However, they usually have a cell wall made of chitin.
- **Kingdom Plantae**: This kingdom includes multicellular organisms that are autotrophic (photosynthetic) and have a cell wall made of cellulose. Therefore, it does not fit the criteria.
- **Kingdom Animalia**: This kingdom consists of multicellular, eukaryotic organisms that are heterotrophic and do not have a cell wall. This fits all the criteria given in the question.

3. **Conclusion**:
- Based on the characteristics and the evaluation of the options, the correct kingdom for the described organism is **Kingdom Animalia**.

### Final Answer:
The heterotrophic, eukaryotic, multicellular organism without a cell wall is included in the **Kingdom Animalia**.
