Study Notes
Characteristics of Living Things
- Living things exhibit movement.
- Living things reproduce.
- Living things respire (breathe).
- Living things grow.
- Living things depend on their environment.
Plant vs. Animal Cells
Plant Cells
- Cell Wall: Provides structural support to the plant cell.
- Chloroplast: Site of photosynthesis.
- Vacuole: Stores water, waste, and nutrients; larger in plant cells.
Animal and Plant Cells
- Cell Membrane: Regulates what enters and exits the cell; protective layer.
- Nucleus: Contains DNA, controls cellular activities.
- Mitochondria: Produces energy for the cell using sugar and oxygen.
- Endoplasmic Reticulum (ER): Transports materials within the cell.
- Golgi Apparatus: Stores and packages proteins.
- Lysosome: Breaks down harmful or large substances.
- Ribosome: Produces proteins.
Microscope Safety Rules
- Clean your workspace.
- Hold the microscope by the arm and base.
- Handle slides carefully.
- Start with the lowest magnification.
- Do not use the coarse focus knob with high magnification (40x objective).
- Turn off the microscope and cover it before storing.
