3 Types of Passive Transport

Simple diffusion, osmosis, and facilitated diffusion
STUDY
PLAY
Active transport
the movment of materials through a cell membrane using energy
osmosis
the movement of water across a membrane(NO ENERGY, high to low, whater ONLY)
lipids
fats that amke up part of the cell membrane.
homeostasis
The ability of a cell to maintain a balance of food, water, and waste within the cell
exocytosis
the process by which a substance is released from the cell through a vesicle that transports the substance to the cell surface and then fuses with the membrane to let the substance out
endocytosis
the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell
simple diffusion
the process by which molecules move from an area of higher concentration to an area of lower concentration
facilitated diffusion
Requiring no cellular energy , this type of diffusion helps move large molecules across the cell membrane through transport proteins found in the cell membrane
cell membrane
a cell structure that controls which substances can enter or leave the cell
