Key Idea: All living things are composed of one or more cells.
Students are expected to know that:
- All organisms, including animals, plants, fungi, and microorganisms, are made up of cells.
- Cells vary in size, shape, and specialized functions.
- Most cells are so small that their details can be seen only with a microscope.
- Living things can be made of just one cell to many millions of cells.
- Some organisms are made of many types of cells and many of each type.
- In single-celled organisms such as bacteria, the single cell carries out all of the functions needed for the organism to stay alive; in organisms made of many cells, individual cells work together with (depend on) other cells to carry out their essential life functions.
- In multicellular organisms, the structures that make up those organisms (including brain, muscles, skin, and lungs in animals, and stems and flowers in plants) are made up of cells.
Boundaries:
- Students are not expected to know the terms "prokaryote" or "eukaryote" or the differences between these types of cells.
- Items will not test students’ knowledge of fungi.
