BIO 152 EXAM 4 WITH CORRECT
ANSWERS 2025
Which of the following statements is most correct concerning the
movement of materials through the stomata? correct answers
>> b) Water and O2 move out; CO2 moves in.
Oxygen gas produced during photosynthesis originates as:
correct answers >> oxygen atoms contained in water molecules
Which of the following statements best represents the
relationship between respiration and photosynthesis? correct
answers >> photosynthesis stores energy in complex organic
molecules, while respiration releases it
the major output of the Calvin cycle is: correct answers >>
G3P
input: co2
if a plant had a mutation in the gene coding for its RuBisCo
enzyme, it would affect its ability to correct answers >> fix
carbon
what molecule donates the electron used in the chloroplast
electron transport chain? correct answers >> water
where would you find RuBisCo on an image? correct answers
>> in green round chloroplast
, the purpose of the light reactions is to ____ correct answers >>
provide ATP and NADPH to the calvin cycle
Suppose you were to use the radioisotope O15 to radioactively
label water that is poured into the soil around a mature plant that
is inside a miniature greenhouse. After a sunny day, where would
you expect MOST of the radioactivity to be found? correct
answers >> in the air around in the greenhouse- because of
cohesion-tension theory (evaporation)
The feature of water that causes it to pull up on other water
molecules within a tube is correct answers >> cohesion
in general water flows correct answers >> from high water
potential to low water potential
The value for Ψ in root tissue was found to be -0.33 MPa. If you
take the root tissue and place it in a 0.1 M solution of sucrose (Ψ
= -0.23 MPa), the net water flow would correct answers >>
be from the sucrose solution into the tissue (bc water will flow to
smallest water potential)
equation for water potential? correct answers >> Ψ=Ψp+Ψs
The properties of surface tension, adhesion, and cohesion are all
due to what force correct answers >> hydrogen bonding
