Summary Introduction
Introduction:
The C3 plants perform photorespiration when the concentration of carbon dioxide is low, and oxygen is high. Photorespiration takes place due to the residual affinity of Rubisco for oxygen. The enzyme assimilates CO2 in C3 plants.

can see the condensation of water on the inside of the plastic bag. Which
of the following best explain the processes required for the bag to accrue

Chlorophyll is composed of a central porphyrin ring and a strongly hydrophobic phytol side chain. Which of the following correctly describes the function of the phytol side chain?
absorbs visible light
energizes an electron
anchors the chlorophyll in the thylakoid membrane
creates fluorescence
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.

- 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 consumedarrow_forwardThe green color of plants is explained by the wavelengths of light that are reflected, transmitted, and absorbed by the chlorophylls in the thylakoids. Which of the following statements is true? Plants appear green because chlorophylls reflect and transmit yellow and green wavelengths of light, and absorb red and violet-blue wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb yellow and green wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb white wavelength of light.

Jamil: The phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves in order to perform cellular respiration. Shantal: The cambium is important for phossynthesis because it allows water into the plant which is needed as a reactant for photosynthesis. Enrique The guard cells are needed during transpiration because they open and close to regulate the gases that enter and leave the plant.

O Anne Jamil O Shantal O Enriquearrow_forwardWhat would you expect to happen to a plant treated with a chemical that inhibits rubisco? OCO2 fixation would decrease the plant wouldn't be able to undergo photosynthesis the plant wouldn't be able to produce cellulose so it would not grow the plant would eventually die due to a lack of energy all of the abovearrow_forward
