Step-by-step explanation:

The Cell Theory

According to the cell theory, all living things are made up of cells, which is the structural unit of living organisms, and living cells always come from other living cells. In fact, each living thing begins life as a single cell. Some living things, such as bacteria, remain single-celled.

Other living things, including plants and animals, grow and develop into many cells. Your own body is made up of an amazing 100 trillion cells! But even you-like all other living things-began life as a single cell.

The tenet of the Cell Theory asked in the question is: All organisms are composed of one or more cells, The cell is the structural unit of life, Cells can arise only by division from a preexisting cell.
