Anteriorly placed, equal, 2-8, flagella are characteristic to

Options

A. Blue green algae
B. Green algae
C. Brown algae
D. Red algae

Answer

To solve the question regarding which group of algae has anteriorly placed, equal, 2-8 flagella, we can follow these steps:

### Step 1: Identify the Groups of Algae
We have four options to consider:
1. Blue-green algae (Cyanobacteria)
2. Green algae (Chlorophyceae)
3. Brown algae (Phaeophyceae)
4. Red algae (Rhodophyceae)

### Step 2: Analyze the Characteristics of Each Group
- **Blue-green algae (Cyanobacteria)**: They are prokaryotic and typically do not have flagella. They can have 2-8 flagella, but they are not equal in size and are not the focus of this question.

- **Green algae (Chlorophyceae)**: They are eukaryotic and can have 2 to 8 flagella that are equal in size and are located at the anterior end. This matches the description given in the question.

- **Brown algae (Phaeophyceae)**: They typically have 2 flagella that are unequal in size and are located laterally, which does not fit the criteria.

- **Red algae (Rhodophyceae)**: They do not have flagella at all, which eliminates them from consideration.

### Step 3: Conclude the Correct Answer
Based on the analysis, the only group that fits the description of having anteriorly placed, equal, 2-8 flagella is **Green algae (Chlorophyceae)**.

### Final Answer
The correct answer is **Green algae (Chlorophyceae)**.
