Question

Which of the following structures is present in a prokaryotic cell and works similar to mitochondria?

Answer 1

Mitochondria and chloroplasts, two organelles found in many eukaryotic cells, contain ribosomes similar in size and makeup to those found in prokaryotes. This is one of many pieces of evidence that mitochondria and chloroplasts are descended from free-living bacteria.

Answer 2

Mesosomes

Explanation:

• Mesosomes are present in prokaryotic cell , it appears as an invagination of the plasma membrane and functions just like mitochondria of eukaryotic cell.
• Mesosomes carry out respiration in bacteria, also it helps in DNA replication and cell division or excretion of exoenzymes.
• It is present in both gram positive and gram negative bacteria.
• They are extremely developed in gram positive bacteria.
• Mesosomes are absent in eukaryotic cell and are analogous to eukaryotic mitochondria
