Question 1

Describe differences between eukaryotic and prokaryotic cells

Answer 1

Eukaryotic cells keep DNA confined to nucleus whereas prokaryotic cell DNA is not confined. DNA of eukaryotes much more complex.Eukaryotic cell is 10 times larger. Prokaryotes cell walls contain peptidoglycan. So,e eukaryotes may have cell walls but none made of peptidoglycan.

Question 2

What is cytosols function in eukaryotic cell

Answer 2

Contains metabolic pathways , protein synthesis
