Chloroplasts are known for all of the following except being:

• A. Responsible for cellular respiration in animal cells
• B. Surrounded by a double membrane
• C. The site of photosynthesis in plant cells
• D. Organelles containing their own DNA

Answer: (A)

Verified step by step guidance

1. Step 1: Begin by understanding the function of chloroplasts. Chloroplasts are organelles found in plant cells and some protists, and their primary role is to carry out photosynthesis, converting light energy into chemical energy stored in glucose.
2. Step 2: Recall that chloroplasts are surrounded by a double membrane. This structure is essential for compartmentalization and the efficient functioning of photosynthesis processes within the organelle.
3. Step 3: Note that chloroplasts contain their own DNA. This allows them to produce some of their own proteins and enzymes necessary for photosynthesis, making them semi-autonomous organelles.
4. Step 4: Understand that cellular respiration is a process that occurs in mitochondria, not chloroplasts. Cellular respiration is responsible for generating ATP in both plant and animal cells, but chloroplasts are not involved in this process.
5. Step 5: Based on the above clarifications, identify the statement that does not align with the known functions and characteristics of chloroplasts. The correct answer is: 'Responsible for cellular respiration in animal cells,' as this is a function of mitochondria, not chloroplasts.
