Final answer:
The cell theory emphasizes that all organisms are made up of cells, cells are the most basic unit of life, and all cells are derived from pre-existing cells. It highlights the universality and fundamental structure shared by all cells, regardless of their diversity.
Step-by-step explanation:
Cell Theory
The cell theory is a crucial principle in biology that contributes to our understanding of living organisms. Fundamental aspects of this theory include the concept that all organisms are composed of one or more cells, that the cell is the basic unit of life, and that all cells arise from existing cells. There are a few universal components that all cells share, such as a cytoplasm inside a plasma membrane, one or more chromosomes which carry genetic information, and ribosomes that are involved in protein synthesis.
In summary, cell theory describes the following properties:
- All organisms are made up of cells.
- Cells are the fundamental units of life that carry out all life's essential functions.
- All cells originate from pre-existing cells, emphasizing the continuity of life.
Furthermore, despite the diversity of cells in size, shape, and function, the basic cellular structure remains consistent across all cell types, contributing to the universality of cell theory.
