It is wise to do review questions at the end of each chapter.

Remember to study concepts as pairs (example)

Osmosis and diffusion

Active and passive transport

Semi and selectively permeable

Endo and exo cytosis

Diffusion quiz

http://biologycorner.com/quiz/qz_diffusion.html

a)   Learn the vocabulary both as a definition and an example

b)   Link the concept to an active example. The operative term is “how”. For example how does the cell membrane allow fats to be absorbed?

c)    Now that you have learned “the bits” and what they do, what happens if they do not work? Example: A new anticancer drug stops cancer cells from actively absorbing glucose, what would occur in the cell membrane and what organelles may be affected?

Number Two

To calculate the mass percent or weight percent of a solution, you must divide the mass of the solute by the mass of the solution (both the solute and the solvent together) and then multiply by 100 to change it into percent.

Special Notes

1)   Introduction: always discuss the problem you are trying to solve and a testable idea (the hypothesis)

2)   In materials and methods: Be specific so that you can go back and find sources of experimental error.

3)   Discussion and Results: This is the section where you manipulate and discuss the data and the lab. In the discussion you can look at sources of error.

4)   Conclusion: Always discuss in a simple statement the following three things:

a)   How did your lab results relate to you testable idea.

b)   What are the specific sources of error?

c)    What variable could you use for a follow up lab
