LIMITED LICENSE TO MODIFY. These PowerPoint® slides may be modified only by teachers
currently teaching the Science and Global Issues SEPUP course to customize the unit to match their
students’ learning levels or to insert additional teaching aides. Modified slides may be used only by the
modifying teacher in his or her classroom, or shared with other teachers of Science and Global Issues
within the teacher’s school district, with these same restrictions. Modified slides may not be taken out of
the classroom or distributed to any non-student person or organization. Except for use with students in
the classroom, modified slides may not be published in printed or electronic form, including posting on
the Internet. Only text may be modified: photographs and illustrations on the slides may not be modified

Activity 2: Cells and Disease
Get
Started


Where do you think cells are involved in
life processes?
Why do you think scientists and doctors
study cells?
Activity 2: Cells and Disease
Introduction
Read the introduction.

A disease is any breakdown in the
structure or function of an organism.
Activity 2: Cells and Disease
Challenge

How do observations of cells
help doctors and scientists
diagnose and study diseases?
Activity 2: Cells and Disease
Using a Microscope
Activity 2: Cells and Disease
Procedure
Part B: Observing Blood


Read the patient histories and table of
possible diseases before you get your
microscope slides.
Compare each patient’s blood sample to
the typical blood sample.
Activity 2: Cells and Disease
Activity 2: Cells and Disease
Follow Up


What diagnosis did you give to Patient A,
and what was your evidence?
What diagnosis did you give Patient B,
and why?
Activity 2: Cells and Disease
Analysis 3

Observe the diagrams below. Which patient would
you diagnose with sickle cell disease? Explain,
using evidence from this activity.
Patient 1
Activity 2: Cells and Disease
Patient 2

Based on the diagrams, how does the shape of
normal red blood cells help them perform their
function? How does the shape of sickled red blood
cells prevent them from performing their function?

Analysis 4

How do microscope observations of cells
help doctors and scientists diagnose and
study diseases? Give specific examples
from this activity.
Activity 2: Cells and Disease
Analysis 5

From what you learned about malaria in the case
study:
◦ A trade-off is an exchange of one thing in return for
another, giving up something that is a benefit or
advantage, in exchange for something that may be more
desirable. What are the trade-offs of using insecticides to
kill the mosquitoes?
◦ What are the benefits of using insecticides to kill
mosquitoes that might be carrying Plasmodium?
