Final answer:

The Cell Theory states that all organisms are composed of cells, cells are alive and the basic living units of organization, and all cells come from other cells.

Step-by-step explanation:

The Cell Theory:

All organisms are composed of cells: This means that every living thing, from plants to animals to bacteria, is made up of one or more cells. Cells are the basic building blocks of life.
  1. Cells are alive and the basic living units of organization in all organisms: Cells are not just static structures, but living entities with the ability to carry out functions such as metabolism, reproduction, and response to stimuli. They are the smallest units of life and are responsible for the organization and function of all living organisms.
  2. All cells come from other cells: This statement emphasizes the concept of cell division and the continuity of life. New cells are always produced from pre-existing cells through processes such as cell division and reproduction.

Answer:

In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.

The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.

Step-by-step explanation:

In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1839.
