15
Q

Hypotonic solution

A

Is a solution of high level of solvent, low level of solute

Ex: distilled water

16
Q

Hypotonic solution has

A

Turgor pressure, contractile vacuoles

17
Q

Turgor pressure

A

Water pressure inside the cell

18
Q

Contractile vacuoles

A

Hypotonic cells need them, organelle to pump water

19
Q

Hypertonic solution

A

High level of solute, a low level of solvent

Ex: salt water

20
Q

Hypertonic solution has

A

Plasmolysis

21
Q

Plasmolysis

A

Shrinkage of a cell due to loss of water

22
Q

Isotonic solution

A

Stays the same

23
Q

Passive transport

A

Move to lower concentration, requires no energy to occur

24
Q

Passive transport has

A

Transport proteins

25
Q

Transport proteins

A

Facilitated diffusion

26
Q

Facilitated diffusion

A

Moves to lower concentration, helps molecules passive transport by using carrier proteins

27
Q

Active transport

A

Move to higher concentration- uses ATP energy

28
Q

Active transport requires

A

Energy to occur, carrier proteins

29
Q

Carrier proteins

A

Help movement of molecules across the membrane

30
Q

Bulk transport

A

Movement of large molecules

31
Q

Bulk transport has

A

Phagocytosis, pinocytosis

32
Q

Phagocytosis

A

Surrounds large solids

33
Q

Pinocytosis

A

Surrounds liquids
