the SQ4R
method, read Chapter 3 in the text. Do the reading and
study exactly as it is described in the
SQ4R
procedure. Do
not cheat on this you're only hurting
yourself! -After
reading the Chapter, and answering what you can of your
objectives, complete the homework assignments listed
below. Copy and past a copy of your objectives into your
word processor. Cut and paste text, and graphics, from
the online activities to make yourself a document that
you can use in your studt group. Ask questions in
class about any of the Objectives
that you could not answer. You must take responsibility
for being as prepared for the exam as you can possibly
be. I will help where I can, but I can't do much if I
don't know what your problems are. You must study until
you are capable of determining if you need help.
Being able to ask
questions and recite with other students can make all of
the difference in your mastery of the material. A group
that can meet face-to-face is the best situation, but if
that can be arranged then using Homeroom
D-140 Post and Discuss
is the
next best thing. Click the link and register. Get your
Study Group members to register and you have a way of
communicating so that on the night before the night
before the exam you RECITE
orally, or write, the answers to the objectives with the
group not using your notes. This will be the final
confirmation that you know the material and are ready to
take the examination. If you are still not ready for the
exam, at least you have one more day to
prepare.
1. Go
to
The
Virtual Cell Tour.
Move
around on the graphic of the cell and click on the
organelles. You'll get a minitutorial on the structure and
function of that cellular organelle. 2. Test your
knowledge of the cell and its parts here. 3. A
cell's plasma membrane has been a focus of research in
understanding cellular metabolism. One traditionally
explained functions of the cell, that of
OSMOSIS,
has finally been explained through the discovery of
AQUAPORINS.
Here are some links to familiarize you with the osmostic
process and aquaporins. b.

6. Go
to
Cultured
Cells.
Read
the text and examine the cell graphics. These are picures
taken with a scanning electron microscope. The colors are
not the true colors of the cells. These colors have been
added with a paint program to enhance their contrast. The
value of these pictures is in seeing the exterior of cells
in a three dimensional form. At
the bottom of the page are links to other pictures. Some are
three dimensional and others are tissue sections that have
been color enhanced. 7.
Use Kimball's
Pages
as a resource to look up information on each of the areas
studied. His text materials are a bit harder to interpret,
but they are thorough. 8.
Test yourself to see how much you've managed to understand
and retain. Click on this link Cell
Quiz.
Take the test and submit it for grading. If
you don't get at least an 80%, then check the questions that
were incorrect and determine where you made your mistake.
After reviewing the test, take it again. 1.

activity will investigate the process of osmosis through the

placed in varying concentrations of salt solutions to see
how their physical features are affected over a 24 hour
period. Simulation will be used to explain the concept of
diffusion.This lab will be evaluated through a lab
examination that will examine the principles of osmosis.

Dennis Kunkel's Microscopy: Science and Photography through
a Microscope An online
collection of micrographs that are works of art. Various
insects, bacteria, and crystals are featured, and the text
that explains each specimen is excellent. Some features of
this exhibit are Image Gallery, Most Wanted Bugs, About
Microscopy, Zoom In, and JavaScript SEM. JavaScript SEM
creates the illusion of controlling a scanning electron
microscope (SEM), an experience worth your time. Every
detail of this site has been carefully planned and awaits
your visit. The Centre for
Microscopy and Microanalysis at the University of Queensland
has compiled a gallery of transmission and scanning electron
microscope micrographs. You can browse various types of
cells, tissues, and crystals. These images are excellent for
class studies and project resources. 15.
Virtual
Cell A series of
still images, texts, and movies portray the structure and
function of a generic plant cell, as students navigate their
way through it. For example, removing the cell wall and then
the plasma membrane provides a view of internal organelles.
Clicking on the chloroplast brings up an inside view, then
close-ups of grana, then photosystems. At each step, a
short, simply worded paragraph, often posing questions,
describes the structure and how it works. Links to images
and descriptions of organelles. Three-dimensional
images of mitochondria. 18.
