Prokaryotic cells

Question 1

nucleoid structure

Answer 1

one molecule of DNA - a super coiled ( and therefore compact) chromosome

Question 2

ribosomes

Answer 2

smaller than those in eukaryotic cells

Question 3

cell wall function

Answer 3

acts as an extra layer of protection, prevents dehydration, helps cell maintain shape

Question 4

cell wall structure

Answer 4

made of peptidoglan (foamed form amino acids and sugars - complex polymer)

Question 5

capsule function and structure

Answer 5

enables the cell to attack to surfaces surrounding it
made of polysaccharide

Question 6

flagella function

Answer 6

locomotion - energy to rotate the filament (that becomes the flagellum) comes from chemiosmosis

Question 7

flagella structure

Answer 7

is attacked to the cell membrane by a basal body and is rotated by a molecular motor

Question 8

prokaryotic cell DNA formation

Answer 8

supercoiled DNA strandswrap around histone proteins to form chromatin which coils and condenses to form chromosomes
