Study Notes
Biology
- The study of living organisms and life
- Includes structure, function, growth, evolution and interactions with their environment.
- Subfields include genetics, ecology, microbiology, and zoology.
- Helps us understand life processes and how organisms interact with each other.
Cells
- Basic building blocks of all living things.
- Smallest unit of life, like tiny factories.
- Carry out functions necessary for an organism's survival.
- Unicellular organisms have one cell.
- Multicellular organisms have trillions of cells working together.
Organisms
- Any living thing, such as a plant, animal, or fungus.
- Can be unicellular or multicellular.
- Bacteria are single-celled organisms.
- Humans are multicellular organisms.
Notes on Organisms
- Organisms grow, reproduce, respond to their environment, and carry out functions for survival.
Key Points
- Living things are called "Organisms."
- Cells are the smallest unit capable of life functions.
- Unicellular organisms are made up of one cell.
- Multicellular organisms are made up of many cells.
- Cells in multicellular organisms are specialized for specific functions.
- All cells come from other cells through cell division.
Cell Growth and Division
- Cell division creates new cells for replacement and growth.
- Single cells are usually too small to be seen without a microscope.
