What are the three tenets of the cell theory of life?

1 answer

The three tenets of the cell theory of life are:

1. All living organisms are composed of one or more cells: This tenet states that all living things, from complex multicellular organisms like plants and animals to single-celled organisms like bacteria, are made up of one or more cells.

2. The cell is the basic unit of structure and function in living organisms: According to this tenet, the cell is the smallest unit of life that can perform all the necessary functions for an organism's survival. It is the structural and functional building block of all living organisms.

3. All cells arise from pre-existing cells: This tenet postulates that cells can only be formed through the division of existing cells. New cells are generated through the process of cell division, where a parent cell divides into two or more daughter cells, each containing a complete set of genetic material.
