1. Section 7.2- Eukaryotic Cell Structure Objectives: Describe the function of the cell nucleus Describe the functions of the major cell organelles Identify the main roles of the cytoskeleton

3.  There are some differences between plant and animal cells  There are some similarities

4.  Organelles – specialized structure that performs important cellular functions within a eukaryotic cell  Nucleus  Ribosomes  Endoplasmic Reticulum (ER)  Golgi Apparatus  Lysosomes  Vacuole  Mitochondria  Chloroplasts  Cytoskeleton

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

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

7.  “The Highway”  “The Highway” (tubes and sacs)  Rough  Produces phospholipids and proteins  Smooth  Produces cholesterols

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

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

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

11.  “The Power House”  Where ATP is produced

12.  Use light energy to make C 6 H 12 O 6 and O 2  Thylakoids  Flattened membranous sacs that contain chlorophyll  Chlorophyll  Pigment that absorbs light and captures light energy for the cell

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