cell transport that requires energy; movement from low to high
concentration
chromosome pairs are pulled apart and move to opposite ends of the
cell
process of cell reproduction
organism that can makes its own food; producer
cell splits into two new daughter cells
cell transport that does NOT require energy; Ex: osmosis & diffusion
two new nuclear membranes form
when particles of a substance move from an area of high
concentration (crowded) to low concentration (not so crowded)
Division of the nucleus
The cell membrane is ______________ permeable. It allows only
certain materials to pass into and out of the cell.

release energy
selectively permeable membrane surrounding cells that controls what
goes in & out of the cell
chromosomes line up in the middle of the cell and attach to spindle
