  1. The Parts of the Cell

  2. Organelles • Organelles are the small structures within cells that perform specific function. • Organelles are composed of proteins and lipids.

  3. The Nucleus • Double-layered membrane. • Contains the genetic material (DNA) of the cell. • Deoxyribonucleic Acid exists as chromatin scattered in the nucleus. www.tqnyc.org

  4. The Nucleolus • Darker area within the nucleus • Manufactures ribosome parts. www.bio-pro.de

  5. Ribosomes • Manufacture substances (proteins) important for cell function. • Free floating or bound to ER. sun.menloschool.org

  6. Endoplasmic Reticulum • Folded membrane • Transports materials (proteins) throughout the cell. • Smooth and rough biology.about.com

  7. Mitochondria • Powerhouse of the cell • Creates energy for the cell • Contains its own DNA www.etsu.edu

  8. Golgi Bodies • Package important materials and secrete them to the outside of the cell. www.botany.unimelb.edu.au

  9. Lysosomes • Break down materials and digest wastes and worn out cell parts. biology.unm.edu

  10. Vacuoles • Fluid-filled storehouses that contain water, food, wastes, and other materials. users.rcn.com

  11. Cytoplasm • Jelly-like material within the cell • It supports the organelles 8e.devbio.com

  12. Cell Membrane • Encloses the contents of the cell • Controls the movement of materials in and out of the cell. www.microscopy-uk.org.uk

  13. Cell Wall • Only in plant cells • Lies outside the cell membrane • Provides support and structure fungus.org.uk

  14. Chloroplasts • Only in plant cells • Responsible for photosynthesis, the trapping of light energy for the synthesis of sugars. • Contains its own DNA www.euronet.nl
