Q

pinocytosis

A

cellular drinking

17
Q

diffusion

A

from high concentration to low concentration

18
Q

facilitated diffusion

A

protein channel that goes from high concentrain to low concentration

19
Q

active transport

A

low concentration to high conentration

transported across a concentration gradiend

  1. need protein channel
  2. requires energy (ATP)
20
Q

filtration

A

based on size and absorbtion

21
Q

osmosis

A

movement of water from high concentration to low

diffusion of water thru a semipermable membrane based on solute concentration

22
Q

solvent

A

liquid part of solution

23
Q

solute

A

substance dissolved in solution

eletrolytes and non electroytes

24
Q

hypertonic

A

more solute and less whater.

if high solute than theres low water

25
Q

hypotonic

A

less solute more water

if solute is low than the water is high

26
Q

isotonic

A

stable environment with no net cahnge

27
Q

two places where filtration occurs

A

capilaries and kidneys

28
Q

capilary

A

lets things leak in and out through filtration

29
Q

major part of cell membrane

A

phospholipid bilayer - acts as doors to factories

30
Q

mitosis

A

cell division

cell grown

cell replace and repair

31
Q

four phases of mitosis

A

prophase

metaphase - LINE UP

anaphase - SPREAD 2 OPPOSITE POLLS

telophose - CHROMOSOMES WIND UP AND NUCLEUS APPEARS

32
