Osmosis + Diffusion

Question 1

osmosis

Answer 1

The diffusion of water molecules across a selectively permeable membrane from an area of high concentration to lower concentration

Question 2

Contractile vacuole

Answer 2

Type of vacuole that removes excess water from a cell

Question 3

diffusion

Answer 3

the Process of moving from areas of high amounts to low amounts

Question 4

what are the 3 ways that molecules can pass through a phospholipid membrane?

Answer 4

1. passive transport
2. active transport
3. vesicles transport

Question 5

passive transport

Answer 5

no energy input to get into a membrane

Question 6

active transport

Answer 6

cell uses energy to pull in or pump out certain molecules

Question 7

vesicle transport

Answer 7

molecules moved across the membrane in bubble-like sacks

Question 8

lower solute concentration

Answer 8

hypotonic

Question 9

higher solute concentration

Answer 9

hypertonic

Question 10

equal solute concentration

Answer 10

isotonic

Question 11

solvent

Answer 11

the LIQUID that dissolved a solid

Question 12

solute

Answer 12

the SOLID that is dissolved by a liquid

Question 13

the plasma membrane is…

Answer 13

permeable, so the substance freely spreads through the cell

Question 14

what needs to get in and out of the cell

Answer 14

anything that is polar

Question 15

osmosis potential

Answer 15

high to low water potential (moves to get equilibrium)

Question 16

active transport concentration

Answer 16

low to high, energy is needed
