Question

The following characters are found common to both mitochondria and chloroplast:

• A. Epidermis
• B. Hypodermis
• C. Endodermis
• D. Pericycle

Hint:

Mitochondria and chloroplasts share similarities such as double membranes, the ability to synthesize ATP, and having their own DNA and ribosomes, which suggest their endosymbiotic origin.

Answer 1

The Correct Option is B

The following characteristics are common to both mitochondria and chloroplasts:
- (A) Double membrane cell organelles: Both mitochondria and chloroplasts are surrounded by a double membrane structure. This is a key characteristic of both organelles.
- (B) Can synthesize ATP's: Both mitochondria (through oxidative phosphorylation) and chloroplasts (through photophosphorylation) have the ability to synthesize ATP.
- (C) Contains ds DNA, 70S ribosomes: Both mitochondria and chloroplasts contain their own circular double-stranded DNA (dsDNA) and 70S ribosomes. These features suggest their evolutionary origin from prokaryotic organisms.
- (D) Found in all living cells: This is not true. While mitochondria are found in almost all eukaryotic cells, chloroplasts are only found in plant cells and certain algae. Therefore, (D) is not applicable. Thus, the correct answer is A, B, C only.
