    1. The Cell: Structure and Function Structure: what something is made of Function: how something works

    2. The CELL THEORY says: All living things are made of cells. Cells are the smallest units or parts of living things. Cells are produced from living cells.

    3. Viruses are not made of cells

    4. Two types of cells:

    5. Example of Prokaryotic cells: Bacteria (single cell)

    6. Eukaryotic cell

    8. Animal Cell

    9. Plant Cell

    10. Animal cell Plant cell

    11. The cell nucleus holds the genetic material of eukaryotic cells (DNA).

    12. Chloroplasts convert light energy and store it as food energy (glucose). This process is called photosynthesis.

    13. Plants Chloroplast 6 CO2 + 6 H2O + energy (from sunlight) C6H12O6 + 6 O2

    14. Mitochondria convert stored food energy into ATP (the energy used by the cell). This process is called cell respiration.

    16. Endoplasmic Reticulum The Rough endoplasmic reticulum gets its name from the presence of ribosomes on its surface. The Rough E.R. is a network of tubes and bags that help in protein synthesis and the production and storage of glycogen. The Smooth E. R. has no ribosomes attached and is where lipids (fats) are produced for making membranes and storing energy.

    18. Endoplasmic Reticulum

    19. Golgi Apparatus (body) The Golgi apparatus (GA), also called Golgi body or Golgi complex, is a series of membrane-covered pouches. The GA modifies proteins and lipids that have been built in the endoplasmic reticulum and prepares them for export outside of the cell.

    21. Activity You are a lab assistant at UCLA. The researcher in charge or your lab has fallen and hit his head. He cannot remember the basic cell biology that you are learning right now! Help him out by writing a letter to him. Explain to him the basic cell biology you have just learned. You must include all of the vocab words, begin each sentence with a capital, and end each sentence with a period. Lastly, remember to state your topic, and to support it in the following sentences, with a good wrap-up sentence at the end.

    22. Activity VOCABULARY: Structure Prokaryotic cell Eukaryotic cell Animal Cell Plant Cell Nucleus Cell wall Organelles Complex

    23. Your Homework 10 Cornell Note Questions from your notes Read and answer questions from section 7-1 and 7-2. Section 7-1 pg 173 #s 1-5 Section 7-2 pg 181 #s 1-5
