Movement of water from high to low concentrations.

Osmosis

2

Three types of  transport

Passive Transport

Active Transport

Movement of Macromolecules

3

Type of solution that is more dilute than the other solution.

hypotonic solution

4

Type of solution that has more solute and less solvent

hypertonic

5

Act as name tags for the cell

Glycolipids 

and 

Glycoproteins

Loss of osmotic pressure in a plant cell

plasmolysis

7

Part of the phospholipid that faces the cytoplasm or the environment

Hydrophillic phospholipid head

8

carbohydrates that attach to hydrophillic heads in the membrane

glycolipids

9

Three types of passive transport

  • Diffusion
  • Osmosis
  • Facilitated Diffusion

10

Two components of a solution

Solvent (water)

Solute (dissolved particles)

11

Loss of osmotic pressure in an animal cell

crenation

12

Exploding of an animal cell

Lysing

13

Type of solution that is more concentrated than the other solution.

hypertonic solution

14

Alternate names for cell membrane

Selectively permeable membrane

Lipid bilayer

Semipermeable membrane

Fluid Mosaic Model

15

Type of transport that takes in large molecules into the cell...so large they can't fit through the phospholipids or the integral proteins.

endocytosis

16

Part of the phospholipid that doesn't like the solvent in the cytoplasm or the environment

Fatty Acid Tails

27

Category of transport that does not require energy from the cell

Passive transport

28

_______ releases large products or waste molecules out  of the cell.  

Exocytosis

29

Type of passive transport involves the movement of gases across the membrane from high to low concentrations

diffusion
