Slime moulds-

Options

A. Are parasite
B. Do not produce spores
C. Do not produce fruiting bodies
D. Saprophytic protists

Answer

**Step-by-Step Solution:**

1. **Definition of Slime Moulds**: Slime moulds are a group of eukaryotic organisms that can live freely as single cells but can aggregate together to form multicellular reproductive structures.

2. **Classification**: Slime moulds belong to the kingdom Protista. They are classified into two main types: plasmodial slime moulds and cellular slime moulds.

3. **Characteristics**:
- **Plasmodial Slime Moulds**: These exist as a large, multinucleate mass called a plasmodium. They are typically found in damp environments and feed on decaying organic matter.
- **Cellular Slime Moulds**: These exist as individual amoeba-like cells that can aggregate to form a multicellular structure when food is scarce.

4. **Reproduction**: Slime moulds reproduce by forming spores. These spores can be dispersed by wind or water and can germinate into new slime moulds when conditions are favorable.

5. **Nutritional Mode**: Slime moulds are saprophytic, meaning they feed on dead or decaying organic matter, playing an important role in nutrient cycling within ecosystems.

6. **Life Cycle**: The life cycle of slime moulds includes a vegetative stage (feeding stage) and a reproductive stage (spore formation). In the vegetative stage, they exist as single cells or a plasmodium, while in the reproductive stage, they form fruiting bodies that release spores.
