Eukaryotic and prokaryotic cells

Question 1

List the differences between eukaryotic and prokaryotic cells

Answer 1

Eukaryotic cells
- membrane bound organelles
- have chloroplasts
- have 80s ribosomes
- cellulose makes up the cell wall in plants
- chitin makes up the cell wall in fungi
- nucleus (linear DNA in chromosomes)
- mitochondria

Prokaryotic cells
- bacterial chlorophyll
- 70s ribosomes
- cell wall is made out of murein and a mucilaginous layer
- no nucleus
- no mitochondria (the cell is too small)
- no membrane bound organelles

Question 2

Answer 2

DNA wrapped around histones = CHROMATIN

Question 3

Answer 3

Chromatin
