question 18
which statement best summarizes describes cell theory?
all living things are made up of cells that can come from non - living matter.
not all living things are made from cells, and some animal cells come from plants.
all living things are made up of cells, and each cell comes from another living cell.
living things can form from cells or other materials.

Explanation:

Cell theory has three main points: all living things are made of cells, cells are the basic unit of life, and new cells come from pre - existing cells. The first option is wrong because cells come from pre - existing cells (not non - living matter). The second option is wrong as all living things are made of cells. The fourth option is wrong as living things are made of cells (not other materials). The third option aligns with the cell theory.

Answer:

All living things are made up of cells, and each cell comes from another living cell.
