Cell Transport Review

STUDY
PLAY
Molecules move from an area of high concentration to an area of low concentration
Diffusion
When the number of molecules is equal in two areas
Equilibrium
Water molecules move from an area of high concentration to an area of low concentration
Osmosis
The diffusion of larger molecules through the cell membrane
Facilitated Diffusion
When energy is required to move molecules
Active Transport
The process of taking substances into a cell by surounding it with the cell membrane
Endocytosis
The process of releasing large particles out of a cell.
Exocytosis
Substances too large pass through the cell membrane and enter through a process called
Endocytosis
Substances too large pass through the cell membrane and exit through a process called
Exocytosis
Plants can dry out as a result of a process called

What does selectively permeable mean?
Selectively permeable is something that allows some things to enter or leave the cell while keeping other things outside or inside the cell. An example is a window screen.
Whats the difference between passive and active transport?
Passive transport moves things through the cell membrane without the input of energy. Active transport moves things through the cell membrane, but, an input of energy is required.
Whats the difference between osmosis and diffusion?
Osmosis moves water, but diffusion moves molecules
