BIO 1500 Exam 2 Study Guide
1. false: Both C4 plants and CAM plants fix carbon by incorporating CO2 into the 4 carbon malate and then use this
to produce high local levels of CO2 for the calvin cycle. The main difference is that in CAM plants, this occrs in different
cells, and in C4 plants this occurs at different times.
2. true: All of the carbon in your body comes from carbon fixation by photoautotrophs. Thus, all of the carbon in your
body way once CO2 in the atmosphere before it was fixed by plants.
3. NADPH, ATP, and CO2: The calvin cycle can occur in the chloroplast as long as the thylakoid is supplied
with
.
-glucose and O2
-H2O and O2
-NADPH, ATP, and CO2
-NADPH, sunlight, H2O
4. true: Moving water within plants is a challenge that increases with plant size. Bryophytes, the most primitive of the
land plants, cannot grow beyond a certain height because they lack vasculature to eflciently transport water.
5. carbon fixation > reduction > regeneration of RuBP: The calvin cycle accomplishes carbon
1/4
, fixation: converting inorganic carbon in the form of CO2 into the organic carbon in the form of carbohydrates. The cycle
can be broken down into three phases, list them in the correct order
6. A: Which of these symbols A, B, C, D in this image of Photosynthesis and Cellular Respiration represents O2?
7. Green algae: From green plant phylogeny which plants were the earliest to evolve?
-green algae
-bryophytes
-mosses
-seed plants
8. C18H32O16: The molecular formula for glucose is C6H12O6. What would be the molecular formula for a
molecule made by linking three glucose molecules together by dehydration reactions?
9. chloroplasts and mitochondria: A biologist ground up some plant leaf cells and then centrifuged the
mixture to fractionate the organelles. Organelles in one of the heavier fractions could produce ATP in the light, whereas
organelles in the lighter fraction could produce ATP in the dark. The heavier and lighter fractions are most likely to
contain, respectively?
10. Chytridiomycota: Aquatic, flagellated fungi that produce haploid gametes by sexual reproduction or
diploid zoospores by asexual reproduction.
