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
In hot, dry climates, plants have evolved mechanisms to avoid photorespiration. Which of the following is FALSE Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a b с d e 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 Open in Readir
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 statements is are TRUE? Ca pathway involves a single C02 fixation step. In CAM plants. stomata are open during day time. Chlorophyll pigments absorb maximum light in the green wavelength. Reaction center of PSI is P700
Rubisco can bind with CO2 or 02. When it binds with O2, it "wastes" some of the energy captured from the sun. This reaction is photorespiration and is favored at high temperatures and low CO2:02 ratios. Which of the following strategies should limit photorespiration (select all that apply). Keep stomata closed. Keep stomata open. Physically separate the light and light-independent reactions. Temporally separate CO2 uptake and fixation.
A) The concentration of CO2 is lower inside a plant cell than in the atmosphere (outside the cell). In your own words, describe how the CO2 levels are kept low inside the plant cell and explain why this is necessary. Assume stomata are open. B) Regarding the situation presented in Part A and assuming that the stomata of the plant leaves are closed, would this favour the induction of photorespiration in a C3 plant? Explain. Make reference to relevant molecule or molecules as needed. Please clearly label your responses as A and B
Which of the following is TRUE about CAM photosynthetic pathway? Compared to the C3 and C4 pathways, CAM photosynthesis results in greater transpiration and water loss. O By separating where carbon is initially fixed inside the leaf tissue, CAM plants can better control the gradient of carbon dioxide between the air and their leaves. CAM photosynthesis is more energy efficient than C3 photosynthesis. Compared to C3 and C4 photosynthetic pathways, the rate of CAM photosynthesis is limited.
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.
C4 plants have higher photosynthetic rates than C3 plants because they have an additional CO2-fixing enzyme located in the bundle sheath cells.

Water from the root to the leaves via the xylem and transpiration from the stomata O Photosynthesis from the leaves via the stomata. O Cellular respiration through the stems. Cellular division within the dermal tissue.
