Mitochondria Evidence Summary Page
Study 1: They picked three
species of birds because these
three species of birds fly
different amounts: Ducks,
Pigeons, and Chickens.
Conclusion: They birds that fly
the most have the most
mitochondria in their chest
muscles. The mitochondria give
the muscles energy.
Study 2: Scientist measured the amount of mitochondria in rats
that exercised 120 minutes a day, 10 minutes a day, and those that
did not exercise at all.
Conclusion: The rats that exercised 120 minutes a day had the most
mitochondria per gram of gram of muscle.
Exercised for 120
minutes a day
Amount of mitochondria 4.67 mg per gram of
muscle
Average weight
353 grams
Exercised for 10
minutes a day
4.21 mg per gram of
muscle
367 grams
Did not exercise at
all
2.97 mg per gram
of muscle
348 grams

Evidence #1. Diabetes. When
there is a mutation in the DRB
gene, patients cannot produce
insulin.
Conclusion: Most people with
diabetes had: mutated DRB
gene and no DRB proteins in
cells. (80%)
Most healthy people had:
normal DRB gene and normal
DRB protein in cells. (90%)

Evidence #2. Glow in the dark cat evidence. The gene for a glowing
protein was put into cats and the cats produced the protein, so they
glowed.
Conclusion: GFP gene put into cat cells. GFP gene gives instructions to
make GFP protein in cat cells. The GFP protein in the cell makes the
cats glow.
Evidence #3. I NEED HELP WEBSITE. The nucleus is like the brain of the cell.
Conclusion: The nucleus is like the brain (control center) of the cell. DNA is
found in the nucleus, and gives orders to the various cell structures of the cell
on what to do. The cell structures do as they are told by the DNA.
Chloroplast Evidence Summary Page
Evidence #1 : A scientist separated the chloroplasts
from Spinach leaves to see if the chloroplasts could
produce chemicals. He put each of 50 tubes in the
dark for 4 minutes, then the light for 4 minutes, and
repeated this. He found that the levels of glucose
increased in the light.
Conclusion: When chloroplasts were in the light, the
amount of glucose around the chloroplast got
bigger.

Evidence #2 : Find the chloroplasts. After
testing many organisms which of them have
chloroplasts in their cells?
You Found MANY Chloroplasts!!
Conclusion: Plants have many chloroplasts in
their cells especially the green parts of plants.
The flower and trunk has a few chloroplasts. NO
ANIMAL cells had chloroplasts.

Evidence #3: 25 g of chloroplasts are placed in
jars with a carbon dioxide and oxygen meter,
and sealed with lids. One jar was placed in the
light for 30 minutes and the other jar was placed
in the dark for 30 minutes. The level of carbon
dioxide and oxygen changed in the jar that was
placed in the light. No change was observed in
the levels of carbon dioxide or oxygen in the jar
placed in the dark.
Conclusion: When in the light, the chloroplasts
change CO2 (carbon dioxide) into O2 (oxygen),
because the jars were sealed.
