Wikipedia and Google are your friends .

The cell theory states that:

- All living things are composed of cells
- All cells are made from pre-existing cells
- The cell is the basic/structural unit of life

Organelles - http://en.wikipedia.org/wiki/Organelles - there will be a table of the different types of organelles. I'd recommend you practice them.

Surface Area to Volume Ratio - I'd recommend you look through your given textbook from school, go to that topic and write down each formula of every shape. Practice the formula, look at the examples, then apply it to the questions.

Hope that helps.
