Even though C4 plants require more ATP per CO₂ fixed, at higher temperatures, they are more efficient than C3 plants. Which of the following explains the effectiveness of C4 plants? contains a mutant form of Rubisco that does not bind to oxygen oxygen is prevented from entering the bundle-sheath cells where Rubisco is found Oduring the night, carbon dioxide is stored as malate so that stomata do not need to open during the day O photorespiration in C4 plants produces energy while in C3 plants, energy is consumed
Photorespiration causes a number of impacts on a plant. Which of these drives the ECOLOGICAL difference between C3 and C4 plants Question 4 options: Rubisco mistakes Oxygen for CO2 The plant uses energy to convert the toxic product of photorespiration back into something less harmful The plant needs a large number of enzymes to be able to regain the energy invested in the 2 carbon molecule produced by photorespiration None of these explain the difference The plant needs to do gas exchange to remove oxygen and add CO2 to the cell doing photosynthesis to avoid photorespiration.
Which type of the following play a role in the gravitropic response of plants according to the statolith hypothesis? amyloplasts chloroplasts receptors calcium ions O O O O

For keyboard navigation, use the up/down arrow keys to select an answer. a b с d C3 plants have no mechanism to avoid photorespiration C4 plants reduce photorespiration by separating the light reaction in the mesophyll cells from the light- independent reaction in the bundle-sheath cells CAM plants minimize photorespiration by collecting and storing CO2 at night and keeping their stomata closed during the day C4 plants include corn, sugarcane, and many grasses CAM plants can undergo photophosphorylation in the absence of sunlight 7 Open in Readin

If a C3 plant that normally closes its stomata during hot, dry conditions were triggered to open them instead, the most likely outcome would be that O water leaves the leaf, decreasing the rate of photosynthesis O glucose leaves the leaf, increasing the rate of photosynthesis O CO₂ enters the leaf, decreasing the rate of photosynthesis O O₂ enters the leaf, increasing the rate of photosynthesis more chlorophyll is made, increasing the rate of photosynthesis
Which of the following scenarios happens during the light-dependent reaction of photosynthesis? Oxygen gas is produced in the thylakoid lumen by the oxidation of water by photosystem I. Ferrodoxin and NADP+ reductase participates in the reduction of NADP+ to NADPH. Carbon dioxide enters the plants via stomata. Rubisco attaches three molecules of ribulose bisphosphate (RuBP) to one molecule of carbon dioxide.
C4 plants have higher photosynthetic rates than C3 plants because they have an additional CO2-fixing enzyme located in the bundle sheath cells.
The warmth of hot flowers attracts pollinators and helps broadcast the flowers’ (often foul) scent. Corpse flower stalks can reach 98°F, as warm as our bodies. The heat and foul odor both occur in pulses produced by the central stalk. How do these flowers get so hot? Amorphophallus and other heatproducing flowers have evolved mechanisms that disconnect cellular respiration from ATP synthesis. In most cells, cellular respiration uses about 40% of the energy in glucose to synthesize ATP, with the rest given off as heat (see Chapter 8). Hot flowers, on the other hand, synthesize very little ATP; instead, almost all of the energy in glucose is released as heat, causing the flower to warm up. Besides the promise of carrion, what other features have flowers evolved that attract animal pollinators?
What among the following would happen to plant exposed to toxin that made thylakoid membranes permeable to protons? a reverasal of proton gradient across thylakoid membrans would result in higher pH in thylakoid lumen than the surrounding stroma reduction of NADP+ inthe chloroplasts would no longer be possible the proton gradient across the ehylakoid membrane woudl be eliminated the transport of electrons by the protein complexes int eh thylakoids would be prevented.
Which statement about C4 and CAM plants is TRUE? C4 and CAM plants have an additional carbon fixing enzyme C4 and CAM plants have reduced rates of cellular respiration. C4 plants separate initial carbon fixation from the light reactions There are no TRUE answers A pineapple is a C4 plant, agave is a CAM plant C4 plants open their stomata only at night
How do C4 plants minimize photorespiration? Multiple Choice Stomata are only opened at night, storing carbon dioxide in the stroma. During the day, the carbon dioxide is released for photosynthesis. Carbon dioxide is fixed twice in different cells. The Calvin cycle occurs in the bundle sheath cells where oxygen concentrations are lower. Carbon dioxide is fixed twice in different cells so that carbon dioxide does not come into contact with rubisco. Stomata are only opened at night, storing oxygen in malate. During the day, the oxygen is released for photosynthesis. Stomata are only opened at night, storing carbon dioxide in malate. During the day, the carbon dioxide is released for photosynthesis.
