Ribosomes- what are they what do they do?? and where are they located??
they are located on the ER small dot-like things... they break down the protiens in the cells.
made by the NUCELOLUS
golgi apparatus- what do they do ?
it's the shipping department!!!!
modify lipids and proteins. packages materials to be exported from cell.
Vesicles- what are they?? and where did they come from??
