Unlike plasmodial slime moulds, cellular slime molds :

Options

A. a) can move as an amoeboid mass
B. b) are haploid organisms except for the giant-celled zygote
C. c) have more than one nucleus per cell
D. d) form fruiting bodies

Explanation

**Step-by-Step Solution:**

1. **Understanding Slime Molds**:
- Slime molds are saprophytic protists that feed on decaying organic matter. They are classified into two main types: plasmodial slime molds and cellular slime molds.

2. **Characteristics of Plasmodial Slime Molds**:
- In plasmodial slime molds, multiple cells merge to form a single, large multinucleated structure called a plasmodium. This structure can move and engulf organic matter.

3. **Characteristics of Cellular Slime Molds**:
- Cellular slime molds, on the other hand, do not merge into a single cell. Instead, they form aggregates of individual cells that retain their identity. Each cell in a cellular slime mold typically has a single nucleus.

4. **Response to Unfavorable Conditions**:
- When conditions become unfavorable, plasmodial slime molds form fruiting bodies, while cellular slime molds form sporangia.

5. **Movement**:
- Cellular slime molds can move as a single aggregate of cells, allowing them to travel short distances in search of food.

6. **Analyzing the Question**:
- The question asks for a characteristic of cellular slime molds that distinguishes them from plasmodial slime molds. The correct answer is that cellular slime molds can move as a single amoeboid mass.

7. **Conclusion**:
- Therefore, the answer to the question "Unlike plasmodial slime molds, cellular slime molds:" is that they can move as a single amoeboid mass.

**Final Answer**: Cellular slime molds can move as a single amoeboid mass.
