Answer;
Living organisms are not created spontaneously.
Step-by-step explanation;
-Cell theory states that living things are composed of one or more cells, that the cell is the basic unit of life, and that cells arise from existing cells.
-Development of this theory during the mid 17th century was made possible by advances in microscopy. This theory is one of the foundations of biology. The theory says that new cells are formed from other existing cells, and that the cell is a fundamental unit of structure, function and organization in all living organisms.
-The cell theory helps define life - all living things are made of cells, and the cell is the basic unit of structure and function of a living thing. The cell has all the processes of an organism in miniature... digestion, respiration, reproduction.
