Explain each concept

□ The cell theory states that all organisms are made of cells

□ The cell is the basic unit of life.

□ All cells come from other cells.

□ All cells have a cell membrane, DNA, cytoplasm, and ribosomes.

□ Most cells are too small to be seen with the naked eye.

□ Materials that cells need to take in or release must pass through the cell membrane.

□ Eukaryotes have linear DNA enclosed in a nucleus and membrane-covered organelles.

□ Prokaryotic cells have circular DNA and organelles that are not covered by membranes.

□ As multicellular organisms develop, their cells differentiate with specific characteristics.
