Cell Transport
Question | Answer |
---|---|
semipermeable | only some particles enter and exit the cell while others are not able to move through the membrane |
cell membrane | maintains homeostasis and regulates what comes in and out of the cell |
diffusion | movement of particles from a high concentration to a low concentration |
osmosis | the diffusion of water from a high to low concentration water concentration toward the higher concentration of solute |
facilitated diffusion | the use of a carrier protein to move substances from a high to low concentration. No energy required |
passive transport | a type of movement the does not require energy, moves substances down the gradient from a high to low concentration |
active transport | a type of movement that requires energy, moves substances against the gradient from low to high |
isotonic | equal(same) movement of water in and out of the cell |
hypertonic | more solute outside the cell and less water so water leaves the cell and the cell shrinks |
hypotonic | less solute outside the cell and more water so water enters the cell and the cell swells |
phagocytosis | large particles(food or bacteria) are surrounded and engulfed by the cell membrane |
pinocytosis | liquid is brought in by a vesicle |
exocytosis | cell pushes large particles and materials outside the cell |
active transport examples | endocytosis, exocytosis, protein pump |
passive transport examples | diffusion, osmosis, facilitated diffusion |
endocytosis | cell engulfs and pulls in large particles and materials into the cell |
protein pump | transport protein that uses energy to move molecules from low to high concentration |
Water LOVES | Solute |
Cell transport type that doesn't use energy | passive transport |
Cell transport type that DOES use energy | active transport |
If water moves into the cell the surrounding solution is ______ | Hypotonic |
If water moves out of the cell, the surrounding solution is ______ | Hypertonic |
