Cell theory consists of three main parts:
1. All living organisms are made up of one or more cells.
– *Example:* Bacteria, which are single-celled organisms, demonstrate that some life forms consist of just one cell.
2. The cell is the basic unit of life.
– *Example:* Human beings are made up of trillions of cells, including red blood cells that carry oxygen, illustrating how cells are fundamental units necessary for life functions.
3. All cells arise from pre-existing cells.
– *Example:* When a cut on your skin heals, new skin cells are produced from existing skin cells, showing that cells must come from other cells.
This framework helps us understand that cells are essential to all living organisms. If you’d like to learn more about this topic or explore other related concepts, feel free to check the extended services page for further assistance!
