• A. Some cells produce chloroplasts
• B. Mitochondria and chloroplasts maybe found in the same cell
• C. Mitochondria and chloroplasts are not found in the same cell
• D. Chloroplasts can revert to mitochondria in certain conditions.

Answer 1

The correct option is B

Mitochondria and chloroplasts maybe found in the same cell

The correct option is B

Explanation of the correct option:

1. Mitochondria and chloroplast both are bounded by a double-membrane envelope and are semi-autonomous organelles
2. They both have their own genome (DNA) and also have their own ribosomes to synthesize proteins.
3. Mitochondria and chloroplast can be found in the same plant cell.

Explanation of the incorrect option:

Option A:

Chloroplasts are present in all green tissues of plant cells and photosynthetic algae.

Option C:

Mitochondria and chloroplasts are found in the same cell.

Option D:

1. Chloroplasts cannot revert to mitochondria in certain conditions.
2. Chloroplasts are only found in plant cells whereas mitochondria are found in both plant and animal cells.

Final answer: The “Mitochondria and chloroplasts may be found in the same cell” statement is true regarding mitochondria and chloroplast.
