basic components of a living system: prokaryotic and eukaryotic cells

Question 1

prokaryotic cells dna and organelles

Answer 1

their dna is not contained in the nucleus
and their organelles are not membrane - bound

Question 2

dna of prokaryotic cell

Answer 2

structure is same as eukaryotic but packaged differently
1 molecule of DNA a chromosome supercoiled to make it more compact

Question 3

prokaryotic cells ribosomes

Answer 3

smaller then eukaryotic cells 70S and then 80S
both necessary for protein synthesis

Question 4

prokaryotic cells cell wall

Answer 4

peptidoglycan
polymer made from amino acids and sugars

Question 5

prokryotic cells flagella

Answer 5

thinner doesnt have 9 2 arrangements
energy to rotate filaments isnt from ATP
flagellum is attached to cell membrane by basal body and rotated by a molecular motor

Question 6

different of nucleus between p and e

Answer 6

p not pesent
e present

Question 7

different of DNA between p and e

Answer 7

p circular
e linear

Question 8

different of extra chromosomal DNA between p and e

Answer 8

p circular DNA called plasmids
e only present in certain organelles like chloroplasts and mitochondria

Question 9

different of organelles between p and e

Answer 9

p non membrane bound
e membrane and non membrane bound

Question 10

different of cell wall between p and e

Answer 10

p peptidoglycan
e chitin in fungi, cellulose in plants

Question 11

different of ribosomes between p and e

Answer 11

p 70s
e 80s

Question 12

different of cytoskeleton between p and e

Answer 12

p present
e present but more complex

Question 13

different of reproduction between p and e

Answer 13

p binary fission
e asexual or sexual

Question 14

different of cell type between p and e

Answer 14

p unicellular
e unicellular and multicellular

Question 15

different of cell surface membrane between p and e

Answer 15

p present
e present
