Students have asked these similar questions
Tobacco leaves contain nicotine, a poisonous compoundthat is energetically expensive for the plant to make.What advantage might the plant gain by using some ofits resources to produce nicotine?
Chewing insects mechanically damage plants and lessen the surface area of leaves for photosynthesis. In addition, these insects make plants more vulnerable to pathogen attack. Suggest a reason why.
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.
