  1. Warm-up • What is the difference between eukaryotic and prokaryotic cells? • Which type of cells do humans have? • So which type of cell is more complex?

  2. Chapter 7.1 Microscope & Cell

  3. Microscope A microscope is an instrument used to make small objects look larger.

  4. Three Types of Microscopes Simple Microscope: only has one lens.

  5. Compound Light Microscope: uses series of light and lenses to magnify objects

  6. Electron Microscope: Uses a magnetic field to bend the beam of an electron

  8. Microscope Parts

  9. The Cell Theory • Robert Hooke – studied cork cells • Schleiden – plant cell • Schwann – animal cell • Cells – basic building blocks of all living things • 1. All organisms composed of 1 or more cells • 2. Cells are the basic unit of organization of organisms • 3. All cells come from preexisting cells

  10. Prokaryote Cells • Unicellular organisms that lack membrane-bound organelles • Example: Bacteria & Archaea

  11. Eukaryote Cells • Contain a nucleus and membrane-bound organelles • Examples: Animals, Plants, Fungi • Organelles – membrane bound structures with in eukaryotic cells, each organelle has a specific function for cell survival

  12. Similarities vs. Differences • cell membranes • ribosomes • Both have genetic material/DNA • cytoplasm • Eukaryotic cells have a nucleus, which contains the genetic material. • The DNA in prokaryotic cells floats freely in the cell. • Eukaryote cells have membrane bound organelles. • Eukaryotic Cells are on average ten times larger than Prokaryotic cells.
