1

what is an isotonic solution?

concentration of solute in the solution= the concentration of dissolved materials inside the cell

2

what is the goal of an isotonic solution?

equality

3

what is a hypertonic solution?

concentration of solute outside the cell is higher then the concentration of dissolved materials inside the cell

4

in which direction is a hypertonic solution moving?

out

5

what happens to the cell in a hypertonic solution?

the pressure decreases and the cell shrivels

6

what is plasmolysis?

when an animal cell shrivels up (death of a cytoplasm)

7

What is another name for plant cell pressure?

turgor pressure

8

what is a hypotonic solution?

concentration of solute is lower in the solution outside the cell than the concentration of dissolved materials inside the cell

9

in which direction does the water move in a hypotonic solution ?

in

10

what happens to the cell that is in a hypotonic solution?

the pressure increases and the cell bursts

11

what is active transport?

movement of molecules from a low concentration to a high concentration

12

whats another name for active transport?

solute pumping

13

What happens during active transport?

nerve cells with sodium (out)- potassium (in) pump

14

What is bulk transport?

movement of large molecules across the membrane

15

what is endocytosis?

movement of large molecules into the cell

16

What is pinocytosis?

"cell dinking"; taking in liquid and forming a vacuole

17

What is phagocytosis?

"cell eating"; taking in a solid particle dissolved by digestive enzymes of a lysosome

18

what is exocytosis?

movement of large molecules out of the cell

19

What is cell culture?

cells growing on glass

20

What is the cell food in cell culture called?

medium

21

What is "medium"?

horse blood/cerum

22

What is cell fraction?

separation of cell parts by high velocity (20,000x) using a centrifuge

23

what is the machine used in cell fraction?

centrifuge

24

what is autoradiography?

injecting radioactive isotopes into cells/ organisms as tracers
