PLANTS	ANIMALS
Plants generally are rooted in one place and do not move on their own	Most animals have the ability to move fairly freely.
Plants contain chlorophyll and can make their own food	Animals cannot make their own food and are dependent on plants and other animals for food.
Plants give off oxygen and take in carbon dioxide given off by animals.	Animals give off carbon dioxide which plants need to make food and take in oxygen which they need to breathe.
Plants cells have cell walls and other structures differ from those of animals.	Animal cells do not have cell walls and have different structures than plant cells
Plants have either no or very basic ability to sense.	Animals have a much more highly developed sensory and  nervous system.

We have been investigating the difference between plant and animal cells by looking under the microscope.  One of the key differences is between the CELL structure.

What are Cells Though?

Video 1: History of Cell Theory TED-ED
Video 2: Bill Nye the Science Guy: What are Cells

Question 1: 
Write a few sentences which summarise these two videos.  Focus on information about what cells are, how they were discovered and what they do.

What are the Differences Between Plant & Animal Cells?

Question 2:
From the two resources compile a list that describes the differences between a plant and animal cell?

Question 3:
What reasons does the video suggest for differences between plants and animals?
