what organelle doesn’t have a membrane
ribosomes
function of Golgi apparatus
to modify and repackage proteins
where are lysosomes made
the Golgi apparatus
what is the cytoskeleton?
a network of fibres found within the cytoplasm (consisting of microfilaments, microtubules and intermediate fibres)
what is the function of the cytoskeleton?
provides mechanical strength to the cell
helps maintain cell shape
function of microfilaments
allow cell movement
what do microtubules make up?
cilia, undulipodia, centrioles
what is a pair of centrioles?
a centromere
how do prokaryotic cells divide?
binary fission
why can prokaryotic cells not undergo mitosis?
they have linear chromosomes
what is a ribosome made of?
rRNA
SER function
to synthesise, store and transport of lipids and carbohydrates
