(function + what cell)

Answer 9

site of chemical reactions

animal + plant + prokaryotic

Question 10

cell membrane

(function + what cell)

Answer 10

controls what enters and leaves the cell + contains receptor molecules

animal + plant + prokaryotic

Question 11

mitochondria

(function + what cell)

Answer 11

contains enzymes for respiration + site of respiration

animal + plant

Question 12

cell wall

(function + what cell)

Answer 12

cellulose in plants + peptidoglycan in prokaryotes + supports the cell

flagella

(function + what cell)

Answer 16

allow the cell to move

prokaryotic

Question 17

pili

(function + what cell)

Answer 17

allow the cell to attatch to surfaces and other cells + transfer of genetic material

prokaryotic

Question 18

slime capsule

(function + what cell)

Answer 18

protects the cell + helps it stick to smooth surfaces

prokaryotic

Question 19

plasmid

(function + what cell)

Answer 19

circular DNA stores extra genes

prokaryotic
