  1. Identifying the components of a Compound Microscope • Class Objective: Identify the major parts of a compound microscope Eyepiece Nosepiece Arm Objective lenses Stage clips Coarse focus Stage Fine focus Diaphragm Light Power switch Base

  2. What are Cells? 9/29/11

  3. Every living thing is made of cells! • Class Objectives: • Identify 3 components that ALL cells have • Explain why cells are important to All living things • Explain where the heck cells come from

  4. What makes a cell? • Class Objectives: • Identify 3components that ALL cells have • Explain why cells are important to All living things • Explain where the heck cells come from 3 things ALL cells have: • Cell membrane (barrier) • DNA(genetic info) • Cytoplasm(fluid)

  5. Sketch both cells in your notebook.Label which is eukaryotic and prokaryotic. • Cell membrane • DNA • Prokaryote • Cytoplasm • Eukaryote • (DNA floating in cytoplasm) • (DNA inside the nucleus)

  6. Important Ideas About Cells:(aka- the Cell Theory) • Class Objectives: • Identify 3 components that ALL cells have • Explain why cells are important to All living things • Explain where the heck cells come from 1. All living things are made of cells. • Unicellular Organisms (one-celled) • Multicellular Organisms (many cells)

  7. Important Ideas About Cells:(aka- the Cell Theory) • Class Objectives: • Identify 3 components that ALL cells have • Explain why cells are important to All living things • Explain where the heck cells come from • Cells give an organism its structure and function - they control everything the organism needs to do to stay alive • Even the most complex organisms are made of • a bunch of different types • of cells working together.

  8. Important Ideas About Cells:(aka- the Cell Theory) • Class Objectives: • Identify 3 components that ALL cells have • Explain why cells are important to All living things • Explain where the heck cells come from • New cells come from pre-existing cells. • A prokaryotic cell splits into two identical cells by the process of binary fission. • A eukaryotic cell splits into two identical daughter cells by the process of mitosis.

  9. Plant Cell Diagram: • Class Objectives: • Identify the major organelles in a eukaryotic cell • Explain the functions of the major organelles in a eukaryotic cell • Make connections between the major organelles in a eukaryotic cell Lysosome Nucleus Golgi Apparatus Ribosome Chloroplast E.R. (rough) E.R. (smooth) Vacuole Mitochondrion Cell Wall Cytoplasm Cell Membrane

  10. Animal Cell Diagram • Class Objectives: • Identify the major organelles in a eukaryotic cell • Explain the functions of the major organelles in a eukaryotic cell • Make connections between the major organelles in a eukaryotic cell Cytoskeleton Cell Membrane Golgi Apparatus Cytoplasm Nucleus Ribosome Mitochondrion Mitochondrion E.R. Lysosome Ribosomes

  11. A day in the life of a cell How Cells Make and Use Proteins

  12. Put this in your notebook: • Class Objectives: • Describe 3 things that proteins do for the body Proteins – Large molecules that do many important jobs in living things, such as: • Form body structures(muscle, bone, hair, eyes, nails, skin) • Act as enzymes to speed up chemical reactions (like digestion) in our bodies • Act as hormones that send signals through the bloodstream [And many other things we’ll learn about later!]

  13. A Day in the Life of The Cell Proteins Proteins are large molecules that do many important jobs in living things, such as: • Form body structures (muscle, bone, hair, nails, skin) • Act as enzymes to speed up chemical reactions (like digestion) in our bodies • Act as hormones that send signals through the bloodstream [And many other things we’ll learn about later!]

  14. A Day in the Life of The Cell Released into blood stream and used as hormone Golgi Apparatus (Modifies and shapes the protein) Ribosome Protein being formed at Ribosome Protein Nucleus Cytoplasm Protein could go to membrane to be released into blood stream Or the protein could go to a lysosome to be a digestive enzyme RNA Vesicle (“bubble” that transports proteins) E.R. Lysosome (transports and packages proteins) RNA Cell Membrane ::Blood Stream:: Food or waste particle DNA ATP energy (for the cell to use) CO2 + H2O Ribosomes (Holds genetic information) Mitochondria Cell Respiration Glucose + O2 (Copies info from DNA and carries it to the Ribosome to make proteins)
