Animal cells
difference between eukaryotic and prokyrotic
euk is complex with DNA pro is simple and lacks membrane bound organs
cell membrane
protective barrier that encloses cell and regulates substances coming in and out of it
cocci
sphere shaped bacteria
bacilli
longer rod shaped bacteria
sphirilli
spiral spaghetti shaped bacteria
nucleus
control center, stores DNA, and controls cells activities
animal vs plant cells
animal: smaller, no cell wall, no nucleus, many vaculoes, cannot synthesis PLANT; larger, cell wall,nucleus on side, one vacubles,
vacuoles (animal cells)
smaller, stores nutrients, water, and waste products
Chloralplasts (plant cells)
preform photosythensis, converting light energy into chemical energy
Central vacuoles (plant)
maintain turgor pressure by storing water, which supports the plants structire
3 parts of cell theory
1 all living organisms are composed of cell(s) 2 cell is basic unit of life 3 all cells arise from pre existing cells
Osmosis
movement f water through a selectively permable membrane
diffusion
movement of molecules from high to low concentration
solution
final mixture when solute is completely dissolved into the solvent
