What environmental factors simultaneously limit photosynthesis? Explain the concept of saturation by applying conditions under which photosynthesis is not limited.
What are some short-term and long-term advantages and disadvantages of genetically changing plant physiological processes, such as photosynthesis and metabolism? Do you think it would affect other p
Why are enzymes critical to the function of cells? That is, why not simply let chemical reactions occur without interference.
Cellular Respiration and Photosynthesis co-exist as paired processes. Photosynthesis converts light energy into organic molecules such as carbohydrates. These molecules are picked up and utilized as
Plants absorb light energy using special molecules called photosynthetic pigments (predominantly chlorophylls). These pigments absorb most of the visible light except for wavelengths in the green pa
Why do leaves of deciduous trees and shrubs in temperate regions change color in the fall? What is involved in this process? What factors may further influence this change, such as street lights, ad
Explain how CO2 enters leaves. What environmental factors control stomatal movement? How are these factors related to physical and chemical properties that control the opening and closing of stomata

Do indoor plants create oxygen as a by-product the same way in which outdoor plants do (through photosynthesis).
Which of these structures is not contained within a pine seed.
When a plant stops growing under conditions that seem (to us) suitable for growth, we say that it has entered into .
Suppose an experiement is performed which included Plant I supplied with normal carbon dioxide but with water that contains radioactive oxygen atoms.
A scientist gradually increases the amount of Carbon Dioxide available to a plant.The plant's rate of photosynthesis increases at first, but then levels off. What else might the plant need to furthe
Give the formula for photosynthesis. For each reactant, indicate where the plant acquires it. For each product, not during what part of photosynthesis it is produced.
The effects of pH and temperature were studied for an enzyme-catalyzed reaction. The following results were obtained.
What happens to photosynthesis when there is a dense covering such as thick forests, clouds or dust from volcano eruptions. What happens to caron dioxide and oxygen levels. What test can be done in
How do plant and animal cells metabolize energy in complimentary ways.
If a plant is kept for many days in the dark, glucose is not produced, even though the sugar producing reactions are called light-independent. Why is glucose not produced in this case.
The oak makes potentially nutritious seeds (acorns) that contain very bitter-tasting tannins. If we could breed the tannin out of acorns, they might become a delicacy.
The desert tends to have two catagories of plants: small grasses of herbs, and shrubs or small trees. The grasses and herbs typically have fibrous roots.
Agent Orange, a combination of two synthetic auxins, was used in Vietnam to defoliate the rain forest during the Vietnam War. Being similiar to natural growth hormones.
