Question

Chromatophores take part in

• A. photosynthesis
• B. growth
• C. movement
• D. respiration

Hint:

Associate "chroma" with color or pigment. In bacteria, chromatophores are specialized structures for photosynthesis. In animals, they are pigment cells for color change.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question asks about the primary function of chromatophores in biological systems.

Step 3: Detailed Explanation:
* Chromatophores: These are pigment-containing cells or organelles found in various organisms. In photosynthetic bacteria (e.g., purple bacteria), chromatophores are membrane-bound vesicles or invaginations of the cell membrane that contain photosynthetic pigments (like bacteriochlorophylls) and enzymes. They are the sites where photosynthesis occurs in these bacteria.
* In animals (e.g., cephalopods, fish, amphibians, reptiles), chromatophores are pigment cells that allow rapid color change for camouflage or signaling. However, in the context of general biology, particularly related to microorganisms, their role in photosynthesis is key.
* Options (b), (c), and (d) describe general cellular processes, but photosynthesis is the specific function associated with chromatophores in photosynthetic organisms.

Step 4: Final Answer:
Chromatophores take part in photosynthesis.
