The movement of molecules in a high concentration to a low concentration.

FACILITATED DIFFUSION

the movement of particles across the plasma membrane using transport proteins without the use of energy.

diffusion of water across a selectively permeable membrane.important for maintaining homeostasis.water will move from where there’s more of it to where there’s less of it

transports molecules out of the cell by an intercellular vesicle that fuses to the cell membrane and spills the cell in a process requiring energy.

ENDOCYTOSIS PHAGOCYTOSIS

is the process by which a cell often a phagocyte or a protest engulfs a solid particle to form an internal compartment

ENDOCYTOSIS PINOCYTOSIS

type of active transport where the vacuole binds with the plasma membrane and secretes material such as hormones from the cell

Allowing certain substances to pass through but not others.

There is more water outside the cell than inside water moves into the cell cell swells up

tending to repel or fail to mix with water. The opposite of hydrophilic.

hypertonic solutionthere is more water inside the cell than outside

iWhat controls osmosis?isotonic solution. concentration of water is the same inside and outside the cell.no net movement of water into or out of the cell

The movement of particles across the plasma membrane against a concentration gradient using energy

The movement of materials through a cell membrane without using energy..

Question	Answer
SIMPLE DIFFUSION	The movement of molecules in a high concentration to a low concentration.
FACILITATED DIFFUSION	the movement of particles across the plasma membrane using transport proteins without the use of energy.
OSMOSIS	diffusion of water across a selectively permeable membrane.important for maintaining homeostasis.water will move from where there’s more of it to where there’s less of it
EXOCYTOSIS	transports molecules out of the cell by an intercellular vesicle that fuses to the cell membrane and spills the cell in a process requiring energy.
ENDOCYTOSIS PHAGOCYTOSIS	is the process by which a cell often a phagocyte or a protest engulfs a solid particle to form an internal compartment
ENDOCYTOSIS PINOCYTOSIS	type of active transport where the vacuole binds with the plasma membrane and secretes material such as hormones from the cell
SEMIPERMEABLE	Allowing certain substances to pass through but not others.
HYPOTONIC	There is more water outside the cell than inside water moves into the cell cell swells up
HYDROPHOBIC	tending to repel or fail to mix with water. The opposite of hydrophilic.
HYPERTONIC	hypertonic solutionthere is more water inside the cell than outside
ISOTONIC	iWhat controls osmosis?isotonic solution. concentration of water is the same inside and outside the cell.no net movement of water into or out of the cell
HYDROPHILIC	Ability to mix with water
ACTIVE TRANSPORT	The movement of particles across the plasma membrane against a concentration gradient using energy
PASSIVE TRANSPORT	The movement of materials through a cell membrane without using energy..
