get into or out of a cell? Which type of cells are
more efficient at allowing materials to be exchanged
with the outside – larger or smaller cells? Why?

11.
Draw a picture of a protein that is located all
the way through a cell membrane and stretches both
inside and outside the cell. Show the structure of
the molecules of the cell membrane and discuss the
polarity of the head and tails of these molecules.
Think about where water is in relation to the cell.

used during passive transport? What is the direction
of a substance’s movement, in terms of that
substance’s concentration gradient?
20.
Define Diffusion.

22.
Name 3 types of passive transport.
23.
Define Active Transport. Is energy from a cell
used during active transport? What is the direction
of a substance’s movement, in terms of that
substance’s concentration gradient?
24.
What nucleotide-based molecule is involved in all
forms of active transport across a cell membrane?
25.
Can active transport take place in non-living
cells? Why or why not?
26.
Name 3 examples of active transport.
27.
In the egg lab, what form of transport did we
investigate? Was it active or passive? What was the
substance that passed through the membrane?
28.
What happened to the egg in a hypertonic
solution?
29.
What happened to the egg in a hypotonic solution?
30.
If a
solution,

solution,
blood cell were placed in a hypotonic

Notebook Test:
Tell what happened in all conditions in the egg lab.
Be able to calculate the surface area and volume of a cell
with a different measurement than what we used in the lab.
Also be able to calculate the surface area to volume ratio.
Be able to answer questions about cells and their
organelles.
Documents that should be in your notebook:
1. Surface area to volume ratio lab - completed
2. Egg Lab - completed
3. Cells and Their Organelles – Completed. Pictures
should be labeled and colored as indicated in the text
(you can use different colors than those suggested).
4. Directed Reading Packet for chapters 3 and 4
(completed)
You can have other materials in your notebook such as:
1. Animal and Plant Cell Comparison
2. Organelle Chart
3. Cell Membrane Picture
4. Comparison of Prokaryotic and Eukaryotic Cells
5. Print outs of powerpoint presentations given in class
