Question 1 1 pts Which of the following statements is TRUE when comparing plants with C3 photosynthesis versus plants with C4 photosynthesis? C3 plants primarily draw their water in through their roots from the soil while C4 plants primarily draw their water into their leaves from the air Both the mesophyll and bundle sheath cells in the leaf of a C3 plant have the task of both capturing CO2 and producing carbohyrates C3 plants require more sunlight that C4 plants C3 plants require less water to survive than C4 plants The leaves of C4 plants can be described as large, broad, flat, and have branching veins

Which of the following statements is true about C3 and C4 plants? A. C3 plants are more successful in hot climates than C4 plants. B. In C4 cells, CO2 is fixed at night to decrease water loss. C. C3 plants deliver CO2 to the Calvin cycle using bundle sheath cells sheltered from leaf air spaces. D. In C3 plants, O2 competes with CO2 for the active site of RuBP carboxylase. E. C3 plants have chloroplasts in both the bundle sheath cells and the mesophyll cells.

QUESTION 2 Which is true about C3 plants response of photosynthesis to temperature? Photosynthesis rates max out at levels below C4 plants Photosynthesis rates increase faster at 35C than they do at 10C Photosynthesis rates plateau at lower rates than C4 plants at lower temperatures. e.g. 10C. Photosynthesis rates keep increasing with increasing temperatures just like C4 plants
