What are the four tenets of the cell theory?
Every living organism consists of one or more cells
Cells arise spontaneously from abiotic factors.
All living cells arise by division of preexisting cells.
The cell is the smallest unit of life.
Cells pass genetic information to their offspring when they divide.
Atoms contain cells so they are considered biotic.
Cellular membranes are made up of which type of molecule?
Most cells are very small because their cell size is limited by the surface-to-volume ratio.
