Question

Identify the similarities between mitochondria and chloroplast
I) Semiautonomous and endosymbiont
II) Possess circular double stranded DNA and 70s type of ribosomes
III) Enveloped by two unit membranes
A) I onlyB) II onlyC) III onlyD) I, II, and III​

Answer 1

Answer:

The correct option is D) I, II, and III.

Explanation:

To find the correct option, we need to know about mitochondria and chloroplast and their similarities.

What are mitochondria?

Mitochondria are cell organelles found in all cells except red blood cells (RBCs) and prokaryotes. It is known as the powerhouses of cells as it produces ATP. ATP is the energy-rich molecule present in all live cells

What are chloroplasts?

Chloroplasts are organelles found in plant cells and certain algae. It contains chlorophyll. It is the site for photosynthesis.

Similarities between mitochondria and chloroplasts

• Both are semiautonomous as they contain DNA, RNA, and ribosomes. So both are able to produce some of their proteins independently.
• Both are considered endosymbionts. As both originate from endosymbiosis of bacteria by larger cells that means they began as bacteria that were engulfed by a larger cell.
• Both possess double-stranded circular DNA and 70S type ribosomes.
• Both are surrounded by a double membrane

Thus, we can conclude that all statements given (I, II, and II) are true to both mitochondria and chloroplast. So the correct option is D)I, II, and III
