Composition of the atmosphere Gas solubility Gas Exchange Fluxes Effect of wind Global CO 2 fluxes by gas exchange Emerson and Hedges Chpts 3 and 10 Sarmiento and Gruber 2002 Sinks for Anthropogenic Carbon. 13.4 Gas exchange in the leaf of a plant. Learning outcomes. Students should be able to understand the following:. How plants exchange gases?. How the leaf of a dicotyledonous plant is adapted for efficient gas exchange. Composition of the atmosphere. Gas solubility. Gas Exchange Fluxes. Effect of wind. Global CO. 2. fluxes by gas exchange. Emerson and Hedges: Chpts 3 and 10. Sarmiento and Gruber (2002) Sinks for Anthropogenic Carbon. 13.2 Gas exchange in single-celled organisms and insects. Learning outcomes. Students should be able to understand the following:. How single-celled organisms exchange gases. How terrestrial insects balance the need to exchange gases with the need to conserve water. using tracers to investigate hydrology and biogeochemistry. BEE 3710. Spring 2011. What is an environmental tracer?. Dissolved constituents, isotopes, particles or physical properties of water that are used to track the movement of water through watersheds. Examples for . calibration of gas . exchange using:. 222. Rn – short term. 14. C - long term. E&H Sections 5.2 and 10.2. Rates of Gas Exchange. Stagnant Boundary Layer Model.. Depth (Z). ATM. 13.4 Gas exchange in the leaf of a plant. Learning outcomes. Students should be able to understand the following:. How plants exchange gases?. How the leaf of a dicotyledonous plant is adapted for efficient gas exchange. Function of Respiration. SBI 3U1. What is the function of the . Respiratory System?. To that ensure that . oxygen. is brought in and . carbon dioxide. is removed from each cell in the body…. . The 4 stages of Respiration:. Gas Laws The atmosphere is made up of gases so we need to know the basic laws of how gases behave Gas laws describe the relationships between the 4 key parameters describing the behavior of gases Temperature (T) Gas Laws The atmosphere is made up of gases so we need to know the basic laws of how gases behave Gas laws describe the relationships between the 4 key parameters describing the behavior of gases Temperature (T) Breathing(External respiration) . The . process of exchange of O2 from the atmosphere with CO2 produced by the cells.. Respiratory Organs . • Direct respiration by diffusion from the environment – sponges, coelenterates, flat worms etc..
