Explanation:
Cell theory is one of the central theories of biology and is universally accepted. It states that all organisms are cellular - that is they are made of cells. It also states that all living things come from other living cells (not spontaneously, or from dead cells). The cell is the most basic unit of life, organisms can be unicellular, but no living thing is 'less' than that.
