Unit 1 Secion 1: prokaryotic cells

Question 1

Prokaryotic/eukaryotic cell size

Answer 1

Prokaryotic - extremely small, less than 2um diameter

Eukaryotic - Larger Cells, 2-200um diameter

Question 2

Prokaryotic/eukaryotic DNA

Answer 2

Prokaryotic - No nucleus, DNA free in cytoplasm, DNA is circular

Eukaryotic- Nucleus Present, DNA inside nucleus, DNA is Linear

Question 3

Prokaryotic/eukaryotic Cell wall

Answer 3

Prokaryotic - Cell wall made of polysaccharide called “PEPTIDOGLYCAN”

Eukaryotic - No cell wall in animal cells, cellulose cell wall in plants, chitin cell wall in fungi

Question 4

Prokaryotic/eukaryotic Membrane bound organelles

Answer 4

Prokaryotic - no membrane bound organelles

eukaryotic - many membrane bound organelles
e.g. mitochondria, SER, RER, lysosomes

Question 5

Prokaryotic examples

Answer 5

Bacterium, e.g. E.coli or Salmonella

Question 6

Eukaryotic examples

Answer 6

Human liver cell, Yeast, Amoeba

Question 7

1mm=?

Answer 7

1um= 0.001mm
1nm=0.000001mm

1,000um in 1mm
1,000,000nm in 1mm
