  1. THE CELL HANDOUTS Chapter 7 Section 7-1

  2. What is the structure that makes up every living thing? • The cell

  3. The Discovery of the Cell What was Anton van Leeuwenhoek one of the first to see in the 1600s? He saw tiny living organisms in a drop of water.

  4. What did a thin slice of cork seem like to Robert Hooke when he observed it through a microscope? The cork seemed to be made of tiny empty chambers.

  5. What did the German botanist Matthias Schleiden conclude? He concluded that all plants are made of cells.

  6. What did the German biologist Theodore Schwann conclude? • He concluded that animals were also made of cells.

  7. 6. How did Rudolph Virchow summarize his years of work? He stated that new cells could be produced only from the division of existing cells.

  8. What are the three concepts that make up the cell theory? • All living things are composed of cells. • Cells are the basic units of structure and function in living things. • New cells are produced from existing cells.

  9. Exploring the Cell Why are electron microscopes capable of revealing details much smaller than those seen through light microscopes? The wavelengths of electrons are much shorter than those of light.

  10. Circle the letter of each sentence that is true about prokaryotes. They grow and reproduce. They have cell membranes and cytoplasm.

  11. Prokaryotes – Organisms whose cells lack nuclei Bacteria

  12. Are all eukaryotes large, multi cellular organisms? • No, some live solitary lives as single celled organisms.

  13. Eukaryotes Organisms whose cells contain nuclei Plants, animals, fungi, protists
