5. Describe the different ways that C4 and CAM plants carry out
photosynthesis, when compared to C3 plants; and then explain in
each case why these differences evolved.
Solutions
Expert Solution
C4 plants are more productive
than C3 plants as they can tolerate high CO2 concentrations and
light intensity. They also do not exhibit photorespiration.
30. What are the advantages of C4 and CAM photosynthesis as
compared to C3 photosynthesis?
a. Carbon dioxide is not needed for the light-independent
reactions.
b. Less sugar is necessary for metabolic activities.
c. High sugar production can be maintained on hot, dry
days.
d. Light dependent reactions are more efficient.
e. Water is not necessary for the light-dependent
reactions.
What are the end products of photosynthesis in C4 and CAM
plants
Group of answer choices
a,Oxaloacetate and pyruvate
b.water and crassulacean acid
c.oxygen and carbohydrate
d.carbohydrate and Oxaloacetate
2.During which of the following human cell cycles does a cell
go from 2N to 1N?
Group of answer choices
a.Meiosis I
b.Meiosis II
c.Mitosis
d.None of the above
3.The MAJOR reason that aerobes cannot live in the absence of
oxygen is that
Group of answer choices
a.The Citric Acid cycle...
a. Describe different steps of non-cyclic
photophosphorylation.
Describe events occurring in the C4 cycle of photosynthesis.
(points: 4) Why C4 cycle is a good adaptation for certain
plants.
In only 3 sentences, compare and contrast the following:
a) CAM and C4 plants
b) Micronutrients and macronutrients (with examples)
c) Apical meristems and lateral meristems
Compare the mechanisms that C3, C4, and
CAM plants use to obtain and use carbon dioxide.
Why would you expect photorespiration on a hot, dry day to occur
less in C4 and CAM plants than in C3
plants?
C3, C4 and CAM plants have advantages and disadvantages under
specific environmental conditions. In theory a hybrid plant
carrying all three mechanisms would have the largest flexibiliy to
respond and do well under various conditions
Indicate what steps should be activated or turned off during the
following environmental conditions and motivate that on an energy
level and water loss how that optimizes photosynthetic yield:
i. 10oC night temperature, 30oC day
temperature, dry ground, high light intensity
ii. 10oC night temperature,...
C3, C4 and CAM plants have advantages and disadvantages under
specific environmental conditions. In theory a hybrid plant
carrying all three mechanisms would have the largest flexibiliy to
respond and do well under various conditions.
Draw a picture combining the three metabolic pathways of C3, C4,
and CAM palnts (C3 with simplified Calvin cycle in the middle),
