Study Notes
Cell Basics
- Cells are the building blocks of all life.
Cell Theory
- There are three parts to cell theory:
- All organisms are composed of one or more cells.
- The cell is the basic unit of life.
- Cells arise from pre-existing cells.
Types of Cells
- Eukaryotic cells include fungi.
- Prokaryotic cells include bacteria and archaea.
Cell Organelles
- Ribosomes synthesize proteins.
- Mitochondria produce energy for the cell.
- Endoplasmic reticulum has various functions, including synthesizing proteins.
- Lysosomes break down and recycle cellular waste and foreign substances.
- Chloroplasts carry out photosynthesis in plant cells.
- The cell membrane regulates the movement of substances in and out of the cell.
Plant Cells
- Plant cells have a cell wall.
- Vacuoles in plant cells store water and other substances.
Microscopes
- The objective lens of a microscope magnifies the image of the specimen.
Kingdoms of Living Things
- The six kingdoms of living things are: Animal, Plant, Protist, Fungi, Bacteria, and Archaea.
