Energy-Water: Plants
Plants Energy to Water Trade-off Ecology in a Changing World
Question | Answer |
---|---|
Dry environments with little available water. | Xeric conditions |
The process by which plants convert carbon dioxide into organic compounds. | Carbon fixation |
Small pores on the leaf surface that allow gases to diffuse in and out of the leaf. | Stomata |
Pairs of cells that control the opening and closing of stomata. | Guard cells |
The process by which plants convert light energy into chemical energy to produce sugars. | Photosynthesis |
The difference in water concentration between two locations, driving the diffusion of water out of the plant. | Concentration gradient |
A type of photosynthesis where CO2 capture and sugar creation both happen in the mesophyll cells. | C3 photosynthesis |
A type of photosynthesis where CO2 capture and sugar creation are spatially separated, leading to reduced water loss. | C4 photosynthesis |
A type of photosynthesis where plants open their stomata only at night to minimize water loss. | Crassulacean acid metabolism (CAM) |
A process during photosynthesis where O2 is combined with sugars, leading to reduced plant photosynthetic efficiency. | Photorespiration |
The ratio of a plant's root biomass to its shoot biomass, indicating investment in acquiring water or sunlight. | Root-to-shoot ratio |
The long-term change in the Earth's climate, including rising temperatures and changes in precipitation. | Global climate change |
Phases of photosynthesis that require light to produce energy-rich compounds. | Light Dependent Reactions |
Phases of photosynthesis that do not directly require light and produce sugars. | Light Independent Reactions |
Series of chemical reactions that convert carbon dioxide into sugars and other organic compounds. | Calvin Cycle |
Enzyme responsible for combining carbon dioxide with a 5-carbon molecule during photosynthesis. | Rubisco |
Molecule formed after the combination of a 5-carbon molecule with carbon dioxide in the Calvin Cycle. | PGA |
