58
Q

cell membranes are selectively permeable, meaning that…

A

some things can enter/exit them

59
Q

forms a thin, protective layer around the cell

A

cell membrane

60
Q

this type of transport requires energy from the cell

A

active transport

61
Q

this type of transport doesn’t require energy expenditure from the cell

A

passive transport

62
Q

includes simple diffusion, facilitated diffusion, osmosis, and filtration

A

passive movement

63
Q

requires ATP and the cell to expand energy, endocytosis, and exocytosis

A

Active movement

64
Q

the movement of particles from an area of high concentration to an area of low concentration until they are distributed evenly

A

diffusion

65
Q

the difference in concentration areas is called the

A

concentration gradiant

66
Q

this occurs when certain molecules can only pass through the cell membrane with assistance from other cellular structures such as large proteins

A

facilitated diffusion

67
Q

the diffusion of water molecules through a semipermeable membrane from a region of higher water concentration (lower solute concentration) to a region of lower water concentration (higher solute concentration)

A

osmosis

68
Q

the process in which the plasma membrane engulfs extracellular material, forming membrane-bound sacs that enter the cytoplasm and thereby move material into the cell

A

endocytosis

69
Q

“cell drinking” the cell takes in fluid filled droplets by forming a pocket in the cell membrane and then pinching off with the fluid and any small nutrients, amino acids, glucose, vitamins, etc. inside

A

pinocytosis

70
Q

“cell eating” the cell engulfs a particle by sending out pseudopods and then consumes the particle with enzymes.

A

phagocytosis

71
Q

the process in which intracellular material is enclosed within a membrane-bound sac that moves to the plasma membrane and fuses with it, releasing the material outside the cell

A

exocytosis

72
Q

particles in the solvent

solute

73
Q

liquid the solute is in

A

solvent

Q

Iso-

A

equal
