VO.110th Biology 8.1


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..
