ribosomes

24
Q

ribosomes are bigger in _ and smaller in _

A

eukaryotes and prokaryotes

25
Q

does bacteria have a cytoskeleton?

A

yes it does since the cytoskeleton can help cell division, this helps bacteria to divide.

Q

membrane polarity

A

non polar body and polar heads

28
Q

is the cell wall just a wall?

A

no, its a mesh that prevents the cell from bursting.
