Organelles Found in Both Animal and Plant Cells
3

• Organelles
• --Structure within a cell that performs a certain
  function

The Nucleus 
5

• 1. The Nucleus
• --Controls the cell
• --Surrounded by a nuclear envelope  
• 2. The Nucleolus--Site where DNA is
• concentrated

3. Endoplasmic Reticulum

• Intracellular pathway moving molecules from one
  side of cell to the other.

3. Endoplasmic Reticulum

• Has two parts
• Moves supplies around cell
• Rough ER
• Interconnected flattened sacs
• Makes phospholipids and proteins
• Studded with ribosomes
• Smooth ER
• Lacks ribosomes
• Builds lipids

4. Golgi Apparatus

• --flattened stacks of membranes
• --Sorts, packages, labels, and modifies proteins
  and lipids from ER
• --releases molecules in vesicles

5. Cytoskeleton

• Has many structures
• Network of tubes and filaments
• Gives the cell structure and shape
• Cilia and Flagella
• Aid in movement
