1

Eukayrote

have nuclei have a nucleus in which their genetic material is separated from the rest of the cell (plants,animals,fungi and protists)

2

Prokaryote

dont have nuclei they have genetic material that is not contained in a nucleus (bacteria)

3

Ribosome

small particles of RNA and proteins spread throughout the cytoplasm

4

Endoplastic reticulum (ER)

cell where lipid components of the cell membrane are assembled as well as proteins that are exported from the cell

5

Lipid bilayer

double layered sheet of the cell membrane

6

Diffussion

process where particles move from a more concentrated area to a less concentrated area in a solution doesnt require energy

7

Osmosis

diffussion of water through a selectively permeable membrane

8

Facilitated diffussion

process where protein channels help the diffussion of molecules across membrane

9

Active transport

occurs when cells move materials from one side of a membane to the other side against concentration difference

10

Endocytosis

process of taking material into cell by infolding of the cell membrane

11

Exocytosis

release of materials from the cell

12

smooth ER

helps make lipids doesnt have ribosomes on surface

13

rough ER

involved in the protein synthesis has ribosomes on surface
