In blue green algal cell, the photosynthetic pigments are found

Options

A. in the chromatophores
B. distributed freely in the peripheral part of cytoplasm
C. attached to thylakoid membranes of chloroplast
D. in the membranes of thylakoids present freely in the cytoplasm

Answer

To answer the question "In blue-green algal cell, the photosynthetic pigments are found," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Blue-Green Algae**: Blue-green algae, also known as cyanobacteria, are photosynthetic prokaryotes. They contain pigments that allow them to perform photosynthesis.

2. **Identifying Photosynthetic Pigments**: The primary photosynthetic pigments in blue-green algae are chlorophyll a, along with accessory pigments like phycocyanin and phycoerythrin.

3. **Location of Photosynthetic Pigments**: In blue-green algae, these pigments are not contained within chloroplasts (as they lack organelles like chloroplasts). Instead, they are found in specialized structures.

4. **Chromatophores**: The photosynthetic pigments in blue-green algae are located in structures called chromatophores. These are membrane-bound compartments where the pigments are embedded.

5. **Cytoplasmic Distribution**: While some pigments may be found freely in the cytoplasm, the primary location for the photosynthetic pigments is within the chromatophores.

6. **Conclusion**: Therefore, the correct answer to the question is that the photosynthetic pigments in blue-green algal cells are found in chromatophores.

### Final Answer:
In blue-green algal cells, the photosynthetic pigments are found in chromatophores.
