The Cell Theory

The Cell Theory is a fundamental concept in biology that states: 1) All living organisms are made up of cells, which are the basic units of life; 2) Cells are the building blocks of structure and function in organisms; and 3) All cells come from existing cells through division. This theory helps us understand that life is cellular and emphasizes the importance of cells in growth, healing, and reproduction. It serves as a foundation for many biological sciences, illustrating the connection between all forms of life, from simple bacteria to complex plants and animals.
