Cell Transport

Cell Transport Study Stack

QuestionAnswer
holds the cell contents and controls what enters and leaves the cell cell membrane
Process by which molecules move from areas of high concentration to area of low concentration diffusion
molecules are pushed from regions of low concentrations to areas of high concentration active transport
process of taking materials into the cell by means of infoldings, or pockets of the cell membrane endocytosis
process by which water molecules diffuse through a membrane osmosis
diffusion occurs with the help of a carrier molecule across a cell membrane facilitated diffusion
The concentration of solutes is the same inside and outside the cell isotonic solution
The solution has a higher concentration of solutes that the cell hypertonic solution
The solution has a lower concentration of solutes than the cell hypotonic solution
membrane of the vacuole surrounding the material fuses with the cell membrane, forcing the contents out of the cell Exocytosis
molecules move with the concentration gradient, molecules spread out, does not require ATP (energy) Passive transport
molecules move against the concentration gradient, active transport requires ATP (energy) active transport
membrane is a fluid structure, which means it can rearrange itself in response to the environment fluid mosaic
“cell eating” extensions of the cytoplasm phagocytosis
pockets from along the cell membrane, fill with liquid and pinch off to form vacuoles within the cell Pinocytosis
