Students have asked these similar questions
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.
The C4 pathway utilizes less ATP than C3 pathway thus enabling C4 plants to adapt to tropical temperatures.
Group of answer choices:
True
False
Why are lemon eucalyptus good as a insecticides, are there any research for them to be effective?

- Which type of plant would stand to gain more from increasing CO2 levels?arrow_forwardA) 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 Barrow_forwardAll plants contain chlorophyll a. In addition, many plants contain other types of chlorophylls and accessory pigments. Suppose a new agricultural technology is developed in which accessory pigments are somehow embedded or injected into crops that naturally have only chlorophyll a. Explain the food production advantage that these plants could hypothetically provide if they could utilize many of these pigments rather than just one type of chlorophyllarrow_forward
