Concept explainers

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.

CO2 and O2 may compete for the active site of rubisco.

Photorespiration is more likely to occur.

Photosynthesis is more efficient.

Gas exchange comes to a halt.

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.
C4 plants differ from C3 plants because C3 plants while C4 plants O gain CO2 via photorespiration; lose CO2 via photorespiration have mesophyll cells that fix CO2 and contain the Calvin cycle; have mesophyll cells that fix CO2 and bundle sheath cells that contain the Calvin cycle concentrate CO2 near rubisco; cannot concentrate CO2 near rubisco can concentrate the CO2 by regulating the stomata closure; can concentrate CO2 at night produce a four-carbon intermediate after CO2 fixation; produce a three-carbon intermediate after CO2 fixation
Which option describes photoperiodism? time of the day when light shines with the most intensity amount of light needed by a plant to exhibit normal growth biological response of a plant to a change in the length of daylight relative to darkness duration of flowering in a plant the light phase of photosynthesis during which photolysis of water occurs
For a given stomatal conductance, how will an increase in atmospheric concentrations of CO2 possibly influence the rate of photosynthesis? How might this affect the water use efficiency of the plant?
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.
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.
What is the major trade-off plants face when they undergo photosynthesis? When they open their stomata to let in oxygen, they can lose water. When they open their stomata to release oxygen, they can lose water. When they open their stomata to let in carbon dioxide, they can lose water. When they open their stomata to let in water, they can lose carbon dioxide.
If a hole is punctured in xylem or phloem elements while transpiration is going on, will liquid or gas come out or go into the elements? Group of answer choices it will come out of both. it will come out for xylem but go in of phloem. it will go in for xylem but come out of phloem. it will go into both.
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.
Identify the strategies that CAM (crassulacean acid metabolism) plants use to minimize water loss while obtaining CO2 (carbon dioxide) for photosynthesis. form a four-carbon molecule as the first step in fixing CO2 Okeep stomata closed throughout the hot and dry seasons Ostore carbon in vacuoles overnight and synthesize sugars during the day O conduct the Calvin cycle in bundle sheath cells instead of mesophyll cells
