|
What is difference b/w prokaryotic & eukarytotic cells? |
Prokaryotic lacks nucleus (has nucleoid) and membrane bound organelles |
|
|
|
What is cytoplasm? |
region between nucleus and plasma membrane |
|
|
|
plasma membrane? |
selective barrier that allows passage of O2, nutrients, and wastes in/out of cell |
|
|
|
what cells need more surface area? |
cells that exchange lots of material w/ surroundings (ex intestinal or neurons) |
|
|
|
how does cell increase surface area w/out adding volume? |
microvilli |
|
|
