Question

21. Evidence in support of the importance of endosymbiosis in the evolution of

eukaryotic cells is:
a, Organelles that have their own unique unique DNA and ribosomes
Organelles that have a double membrane
6. Organelles are in the same size range as free living prokaryotes
d. All of the above

Answer 1

d. All of the above

Step-by-step explanation:

The theory of endosymbiosis is important as it explains the evolution of eukaryotic cells from prokaryotic cells.

This theory also explains the origin of chloroplast and mitochondria. Several evidences in support of the importance of endosymbiosis in the evolution of eukaryotic cells are as following:

• Organelles have their own separate DNA and ribososme.
• Organelles that have a double membrane (inner and outer).
• Organelles are in the same size range as free-living prokaryotes.

Chloroplast and mitochondria are the examples of such organelles.

Hence, the correct answer is "d".
