CELL WALL

WHAT DOES THIS ORGANELLE DO?

• Provides protection and support
• It keeps all the other organelles inside
• Allows nutrients and oxygen to enter
• Allows waste to flow out
• Gives the plant cell its shape

OTHER FACTS YOU SHOULD KNOW

• Only plant cells have a cell wall
• Major part in the cells framework
• It is mostly made out of cellulose (makes it strong)
• It is multilayered and has three sections (just like cake!)
• Cell wall Layers: middle lamella,primary cell wall, and secondary
• Cake Layers: chocolate, vanilla, strawberry, ect

WHAT WOULD WE DO WITHOUT IT?!

• Without the cell wall the plant wouldn't have a chance of surviving
• Just like without superman all of the town will be full of criminals (bacteria)
• The organelles might escape without a cell wall
• The cell wall keeps the bacteria out

WHY DO WE NEED IT?

• The plants will have no structure without the cell wall
• The wouldn't be able to handle tugor pressure
• Keeps everything inside the cell

LETS REVIEW

• It protects the plant cell
• It keeps everything inside
• It gives the cell and the plant its shape
• Only plant cells have a cell wall
• Without it the plant wouldn't have a chance of surviving
