1. If a plant and a mouse were placed in a sealed container
with a water source, both the organisms will benefit form each other in the
following ways:
1.
The mouse would get oxygen from the plant due to
photosynthesis
2.
The plant would get carbon dioxide from the
mouse’s breathing
Additionally, both organisms would grow and have longer
lives due to the water source provided.
2.
a)
Measuring O2 levels can help provide an
indication of the rate of “photo” reactions because the energy captured from
the splitting of water molecules can be determined. Since oxygen is produced
when water molecules split, we can therefore determine the rate of “photo”
reactions.
b)
With a bicarbonate solution (another source of
CO2), the plant would utilize the molecule’s CO2 during photosynthesis to
produce both sugar and oxygen.
c)
By increasing the amount of CO2, the plant is
provided with more “food” and due to this abundance, the plant will need to
work faster to compensate. Thus increasing the “photo” reactions.
3. I believe that it
is cellular respiration that is occurring at a faster rate, because when a
plant grows quicker it has an abundant source of “food”, in this case glucose,
to feed on. With an abundance of glucose, the plant will want to break up the
sugar to become useable energy for the plant.
