Which of the following groups contain typically coenocytic forms ?

Options

A. Lichens
B. Phycomycetes
C. Liverworts
D. Chlorophyceae.

Answer

To solve the question "Which of the following groups contain typically coenocytic forms?", we will follow these steps:

### Step-by-Step Solution:

1. **Understand the term "coenocytic":**
- Coenocytic (or syncytial) refers to a type of fungal structure that is multinucleated and lacks septa (cross-walls) between cells. This means that the cytoplasm is continuous and contains multiple nuclei.

2. **Evaluate the options provided:**
- The question likely provides several groups to choose from. We need to analyze each group to see if they typically exhibit coenocytic forms.

3. **Analyze the first option - Lichens:**
- Lichens are a symbiotic relationship between fungi and algae. They are not coenocytic because they consist of distinct fungal and algal cells. Therefore, this option is incorrect.

4. **Analyze the second option - Zygomycetes:**
- Zygomycetes are a group of fungi that typically have coenocytic hyphae. They do not have septa in their hyphae, making this option correct.

5. **Analyze the third option - Liverworts:**
- Liverworts are non-vascular plants (bryophytes) and do not have coenocytic structures. They are made up of distinct cells, so this option is incorrect.

6. **Analyze the fourth option - Chlorophyceae:**
- Chlorophyceae refers to green algae, which also do not exhibit coenocytic forms. They consist of individual cells, making this option incorrect.

7. **Conclusion:**
- Based on the analysis, the only group that contains typically coenocytic forms is **Zygomycetes**.

### Final Answer:
The correct option is **Zygomycetes**.
