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 the characteristics of organisms with anteriorly placed, equal, 2-8 flagella, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Characteristics**: The question specifies that we are looking for an organism with anteriorly placed, equal flagella, numbering between 2 to 8.

2. **Consider the Types of Algae**: The main groups of algae to consider are:
- Green Algae (Chlorophyta)
- Red Algae (Rhodophyta)
- Brown Algae (Phaeophyta)
- Blue Green Algae (Cyanobacteria)

3. **Analyze Green Algae**:
- Green algae typically have chlorophyll a and b, store starch, and have a cell wall made of cellulose.
- Importantly, they can have flagella that are equal in number and can be present anteriorly.

4. **Analyze Red Algae**:
- Red algae contain chlorophyll a and d, and their food storage is in the form of floridean starch.
- They generally do not have flagella, making them an incorrect option.

5. **Analyze Brown Algae**:
- Brown algae have chlorophyll a and c, with food stored as mannitol and laminarin.
- Their flagella are usually unequal and not positioned anteriorly, thus eliminating them as a possibility.

6. **Analyze Blue Green Algae**:
- Blue green algae (Cyanobacteria) are prokaryotic and do not typically possess flagella in the specified range (2-8) or characteristics.

7. **Conclusion**: After analyzing the characteristics of each type of algae, the only group that fits the description of having anteriorly placed, equal flagella in the range of 2 to 8 is **Green Algae**.

### Final Answer:
The correct answer is **Green Algae (Chlorophyta)**.
