Definition
is a thick, jellylike substance found in both plant and animal cells filling the space between the nucleus and the cell membrane. It contains and supports the cell organelles. - Where most of the cellular metabolism occurs.
- Though mostly water, is full of proteins that control cell metabolism including signal transduction
