PPT-Breathing & exchange of gases

BreathingExternal 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. 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. 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. Oxygen is needed for _______________. Oxygen is needed for . cellular respiration.. What is the difference between breathing and gaseous exchange? . Discuss with a peer. 1 and . half minutes. After respiration the oxygen gas . 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) Kinetic Molecular Theory of Gases. This is the six point model that is used to explain the behavior of gases. Points of the Kinetic Molecular Theory. 1. Gases are composed of atoms or molecules that have mass. 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.. 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. This document has been reproduced directly from the best available copy.Available to DOE and DOE contractors from the Office of Scientific andTechnical Information. P.O. Box 62, Oak Ridge, TN 37831.A In groups. discuss what is meant by the word “exchange”. Apply the word exchange to a biological concept. Exchange takes place over surfaces. Write down features of a good exchange surface. Which processes are used in the exchange of substances. Learning objectives:. Must say what the job of the lungs is and name the main parts. Should describe the special features the lungs have to do their job really well. Could explain how the alveoli work. 1. Pulmonary ventilation. = exchange of gases between lungs and atmosphere.. 2. External respiration. = exchange of gases between alveoli and pulmonary capillaries.. 3. Internal respiration. = exchange of gases between systemic capillaries and tissue cells..
