How will the CO2 concentration change in the field influence leaf photosynthesis measurements?
Step by step
Solved in 4 steps
- What is photosynthetic rate and how do you measure it in leaves?Refer to the graphs which were generated from photosynthesis rate data collected at varying temperatures from two species of plants measured under different CO2 levels. CO2 CO2 60 Y Y 50 40 30 20 10 15 20 25 30 35 40 45 50 15 20 25 30 35 40 45 50 Leaf temperature (°C) Match the correct labels to the graphs. Net photosynthesis (umol m-2 s-')How do CAM plants, such as cacti, prevent excessive water loss in desert climates? How does this affect their photosynthetic process?
- Where in plant cells does the Calvin cycle take place? a. thylakoid membrane b. thylakoid space c. stroma d. granumWhy do plants need to exchange gases with the environment?Discuss whether it would be more beneficial to improve the light or dark reactions in order to enhance photosynthesis for a future scenario of extreme drought conditions. Please draw sketches to illustrate and include atleast 20 points
- If I wanted to maximize the rate of photosynthesis in plants, should I expose them on Low Light or moderate?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 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 ReadinIf a leaf disc is exposed to light but not to CO2, why would it not produce enough O2 to float?
