Functions of Cell Membrane

• Controls what molecules enter and exit the cell
• Protects and Supports the cell
• Helps cell communicate with other cells

5
Cytoplasm

• Structural Features
• Jelly like material made of water, salt and
  organic compounds
• Function
• Contains organelles

6
Endoplasmic Reticulum (ER)

• System of membranous tubules and sacs
• Can be rough with ribosomes attached
• Can be smooth no ribosomes

7
Functions of the ER

• Rough ER
• Site of new protein production
• Smooth ER
• Highways that proteins move through and storage
  site for proteins

8
Mitochondrion

• Structural Features
• Bean Shape
• Surrounded by 2 membranes
• Functions
• Energy center or Powerhouse of the cell
• Turns food into useable energy (ATP)

9
Nucleus

• Structural Features
• Surrounded by a double membrane called the
  Nuclear Membrane or Envelope
• Has pores
• Contains Chromatin DNA Protein
• Contains the Nucleolus which makes ribosomes
• Contains Nucleoplasm which is cytoplasm of the
  nucleus

10
Functions of the Nucleus

• Directs all cell activities reproduction and
  protein production
• Brains of the cell

11
Ribosomes

• Structural Features
• Small, globular (round) organelles
• Function
• Site of protein synthesis (production)

12
Lysosome

• Structural Features
• Tiny, round organelle
• Single Membrane
• Contains many enzymes
• Function
• Digests food particles, bacteria and broken cell
  parts

13
Golgi Apparatus

• Structural Features
• Flattened stacks of membranes (Pancakes)
• Function
• Processes, modifies
• and packages proteins

14
Microtubules

• Structural Features
• Long, slender protein tubes
• Function
• Supports cell

15
Flagella

• Structural Features (2 Types)
• Many small hair like projections
• One large tail
• Function
• Gives cell the ability to move
