4. Advise for Life Science
Organize your information from beginning to end.
This will help you understand the many step by step processes we will run into.
Example
Hooke sees cell in cork  Leeuwenhoek sees many one- celled organisms  Schleiden concludes that all plants are made of cells  Schwann concludes all animals (and all living things are made of cells  Virchow proposes that new cells form only from cells that already exist.

8. An overview of Cells Why do you need a microscope to see cells?
They are too small to be seen with the naked eye.
What are cells?
The basic unit of structure and function in living things
Cells and structure:
The structures of living things are determined by the amazing variety of ways in which cells are put together.
Cells and Function:
An organism’s function are the processes that enable it to stay alive and reproduce.
Obtaining oxygen
Food
Growing
