  1. Chapter 7Cell Structure and Function Section 7.1- Life is Cellular Section 7.2- Eukaryotic Cell Structure Section 7.3- Cell Boundaries Section 7.4- Diversity of Cellular Life

  2. Section 7.2- Eukaryotic Cell Structure

  3. Basic Parts of a Cell

  4. There are some differences between plant and animal cells There are some similarities Comparing Cells

  5. Nucleus • “The Brain” • DNA, surrounded by nuclear envelope, nucleolus- where ribosomes are made

  6. Ribosomes • “The Construction Company” • Builds proteins • Free floating in the cytoplasm or attached to the ER

  7. Endoplasmic Reticulum • “The Highway” (tubes and sacs) • Rough • Produces phospholipids and proteins • Smooth • Produces cholesterols

  8. Golgi Apparatus • “The Post Office” • Receives proteins from ER • Modifies, labels and directs proteins to locations in the cell

  9. Lysosomes • Specialized organelles • Lysosome- “The Killer or Garbage Truck” • Breaks down molecules • Maintains cell’s health by getting rid of non-functioning parts

  10. Vacuole • Specialized organelles • Vacuole- “The Storage Center” • Stores water, nutrients and waste

  11. Mitochondria • “The Power House” • Where ATP is produced

  12. Use light energy to make C6H12O6 and O2 Thylakoids Flattened membranous sacs that contain chlorophyll Chlorophyll Pigment that absorbs light and captures light energy for the cell Chloroplast

  13. Cytoskeleton • “The Infrastructure” • Cell support • Microtubule • Hold organelles in place • Microfilaments • Cell movement • Intermediate Filaments • Maintain internal shape of cell
