Study Notes
Cell Structure and Function
- The cell is the smallest fundamental unit of structure and function in living organisms.
- Organelles are specialized structures within cells that perform specific functions necessary for cell survival.
Classification of Organisms
- Viruses are not considered living organisms because they cannot replicate independently and require a host cell to survive.
Levels of Biological Organization
- The organ level of organization includes the formation of specialized tissues making up organs.
Biomolecules
- Macromolecules are formed by combining smaller units called monomers.
Viral Replication
- The main requirement for viruses to make new copies of themselves is the presence of a host cell.
Cellular Differences
- The main difference between prokaryotic and eukaryotic cells is the presence of a true nucleus and membrane-bound organelles in eukaryotic cells.
Ecosystems
- The biosphere (Global Ecosystem) includes all ecosystems on Earth, covering all aspects of life and the environment.
- An ecosystem comprises all living organisms (biotic factors) and non-living components (abiotic factors) in a specific environment.
Ecosystem Components
- In a forest ecosystem, all the pine trees collectively represent a population.
