Study Notes
Cell Theory
- The modern version of the cell theory includes four principles: All living organisms are made up of one or more cells, the cell is the structural and functional unit of all living things, all cells come from pre-existing cells through cell division, and all cells contain genetic information encoded in DNA that is passed to daughter cells during cell division.
- Most living organisms are made up of eukaryotic cells.
- Some living organisms are made up of prokaryotic cells.
- All cells contain genetic information encoded in DNA, which is passed to daughter cells during cell division.
- The basic chemical composition of all cells is mostly the same: carbohydrates, nucleic acids, and lipids.
- Metabolism governs the flow of energy within cells.
- The cell theory is a fundamental principle of biology.
- Viruses share some features with living organisms, but are not considered cells.
- The development of the microscope enabled scientists to observe the cell.
Cell Components
- Prokaryotic cells are simpler and smaller than eukaryotic cells.
- Eukaryotic cells are more complex and larger than prokaryotic cells.
- The cell cycle is the process of cell division in eukaryotic cells.
- Prokaryotic binary fission is the process of cell division in prokaryotic cells.
Cell Theory
- Cell Theory states that all living organisms are composed of one or more cells and that all cells come from pre-existing cells
- Unicellular Microorganisms demonstrate that cells can be the building blocks of larger organisms and also exist independently
- The Cell Theory also includes that all cells contain genetic information, encoded in DNA, which is passed to new cells during cell division.
- **The basic chemical composition of all cells is the same. **
- Metabolism governs the flow of energy within cells.
- Infectious Agents such as viruses, while not considered cells, share some features with living organisms.
