  1. Chapter 5CELL STRUCTURE AND FUNCTION VOCABULARY

  2. CELL THEORY • A theory that explains the relationship between cells and living things

  3. Cell membrane cell membrane - a separating barrier that controls movement of materials into and out of the cell.

  4. Organelle organelle - a structure inside of a cell that helps it perform its functions.

  5. Cytoplasm cytoplasm - a fluid mixture that contains the organelles and the compounds the cell needs.

  6. Prokaryotic cell prokaryotic cell - a cell that does not have a nucleus or membrane-covered organelles.

  7. Eukaryotic cell

  8. Mitochondria • An organelle that produces much of the energy a cell needs to carry out its functions.

  9. Vacuole • An organelle that stores food, water, and other materials needed by the cell. • c Central vacuole Vacuole

  10. Cell Vocabulary (continued) • Endoplasmic reticulum – an organelle that transports proteins inside of the cell. • Ribosome - an organelle that makes proteins. • Golgi body - an organelle that receives proteins, packages them, and distributes them. • Lysosome - an organelle that contains enzymes that break things down to be reused by the cell. • Cytoskeleton - a series of protein fibers inside of a cell that give structure and shape to the cell. • chloroplast- an organelle that converts light energy into chemical energy in the form of molecules. • cell wall- the outer layer of a plant cell that is made from cellulose and makes plant cells rigid.
