Unit 2

Cell Structure and Function

What two thing do all of these things have in common?

Explain your answer, and be prepare to defend.

Brainstorm

• List as many things as you can that your cells do within your body.

– Don’t “think” too much.

– Just write.

– No wrong answers.

• 5 MINUTES

Cell Structure Notes

• Write the name of the organelle.

• Sketch the appearance – they all look different, just get a general idea.

• Write what it does.

• Create an analogy.
