Cell Differentiation

– M-H video – cell structure and function – https://www.youtube.com/watch?v=chTptrvKbfg&t=3s

– The process by which cells become different types of cells is called cell differentiation.

– Read pages 97-99. Chunk each page – 1 person read page 97, 1 person read page 98, 1 person read page 99. Then, get together and discuss what you read with your table. Be ready to share with the class.
