3 Types of Passive Transport
Simple diffusion, osmosis, and facilitated diffusion
the movment of materials through a cell membrane using energy
the movement of water across a membrane(NO ENERGY, high to low, whater ONLY)
fats that amke up part of the cell membrane.
The ability of a cell to maintain a balance of food, water, and waste within the cell
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
the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell
the process by which molecules move from an area of higher concentration to an area of lower concentration
Requiring no cellular energy , this type of diffusion helps move large molecules across the cell membrane through transport proteins found in the cell membrane
a cell structure that controls which substances can enter or leave the cell
