2.6 eukaryotic and prokaryotic cells

Question 1

what are the two similarities of prokaryotic and eukaryotic cells

Answer 1

• both have organelles
• both have phospholipid bi-layer cell surface membranes

Question 2

What are the 4 differences between prokaryotic and eukaryotic cells ultrastructure

Answer 2

1. P: single celled organisms eg. bacteria
   E:make up multicellular organisms
   2.P:binary fission
   E:mitosis or meiosis
2. P: circular DNA in cytoplasm
   E: linear DNA in nucleus
3. P: smaller 70s ribosomes
   E: Larger 80s ribosomes

Question 3

Prokaryotic cell:

Answer 3

A type of cell that does not contain any membrane bound
organelles or a nucleus.

Question 4

Eukaryotic cell:

Answer 4

Eukaryotic cell: A type of cell that contains a nucleus along with membrane
bound organelles.

Question 5

Answer 5

bacteria

Question 6

give and example of eukaryotic organisms

Answer 6

plant
agae
animal

Question 7

Organelles of prokaryotic

Answer 7

flagellum-A whip-like structure found on bacterial cells that is used for cell movement.
cilia- Small hair-like structures that project from the surface of cells.
Cell wall- made up of murein

Question 8

Endosymbiosis theory

Answer 8

that mitocondria and chloroplast and possibly other eukaryotic organelles were formerly free living bacteria

Question 9

evidence for the Endosymbiosis theory

Answer 9

mitochondria have their own 70s ribosomes
mitochondria have their own closed loop of DNA
Mitochondria are double membrane bound
Mitochondria reproduce via binary fission

Question 10

endosymbiotic

Answer 10

‘Endo’ within
‘symbiotic’ working together
