The rate at which wastes are produced depends on a cell’s…..
VOLUME SURFACE AREA
or
As a cell becomes larger, which increases faster???
Therefore, cells have more trouble moving needed materials in and waste products out.

In prophase, chromatin condenses so that ___________________ are now visible. The nuclear ___________________ disintegrates. Centrioles separate and chromosomes attach to ______________. Chromosomes line up along the _________________. Centromeres _______________ and sister chromatids ____________________ and move to opposite sides of the cell. Spindles break apart, __________________ begin to disperse, and the nuclear envelope ________________.
In ______________ cells, the cell membrane pinches inward.
In ______________ cells, a cell plate forms between the nuclei.
