Terms	Definitions
diffusion	the movement of particles from high concentrations to low concentrations
osmosis	the movement of water molecules from high concentrations to low concentrations
semipermeable	allowing only certain things to pass through
passive transport	the movement of particples through a membrane that doesn't require the cell to use energy
active transport	the movement of particples through a membrane that does require the cell to use energy
endocytosis	the process where a cell brings a particle into the cell (enters)
exocytosis	the process where a cell releases a particle out of the cell (exits)
photosynthesis	the process where a cell takes in sunlight, CO2, and water to produce glucose and oxygen
cellular respiration	the process where a cell takes in glucose and oxygen to produce energy (ATP), water, and CO2
mitosis	the process of cell division where the cells produced have the same number of chromosomes as the parent cells
interphase	the first phase of mitosis where the chromosomes are copied
prophase	the second phase of mitosis where the nuclear membrane dissolves and chromosomes condense
metaphase	the third phase of mitosis where the chromosome pairs line up along the equator of the cell
anaphase	the fourth phase of mitosis where chromosomes are pulled to opposite sides of the cell
telophase	the fifth phase of mitosis where a nuclear membrane surrounds each set of chromosomes
