PPT-H.6 GAS EXCHANGE Occurs by bulk flow of gasses and by diffusion of gasses through tissue

H61 Define partial pressure Daltons Law of partial pressure states that the total pressure exerted by a mixture of gasses is the sum of the pressures exerted independently by each gas in a mixture. 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. By Myre and William. Gasses. Gasses are particles that float from earth to the . atmosphere and its particles go around to fill every place in a container and when the . they are open they will go to every space around.. DIFFUSION: DEFINITIONS. Diffusion is a process of . mass transport. that involves the atomic . or molecular motion. .. In the simplest form, the diffusion can be defined as the . random walk. of an ensemble of particles from regions of high concentration to regions of lower concentration. HMS. (Preliminary).

Water flow that occurs when the soil is infiltrated to full capacity and excess water from rain, . osmosis . active transport. in . cells . Movement of molecules into and out of cells. T. ransport can be passive or active.. P. assive requires no energy and moves down a concentration gradient from high to low concentration. 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. Fluids. Gasses. Liquids. Ideal Gas. Gasses with particles that undergo . elastic. collisions. Only exist under certain conditions. Low heat. Low pressure. Pressure. Pressure. Barometer. Boyles Law. Boyle’s law shows the kinetic theory mathematically. . Air is a fluid (but not a liquid) that behaves similarly to water. We see pressure changes in the subsurface due to barometric pressure and other causes.. We see gas flow in the subsurface due to advection and diffusion due to pressure and concentration gradients, respectively. Chapter 11-Key Issue #2. Why are situation and site factors important?. Proximity to inputs. Manufacturers try to locate their factories as close as possible to both buyers and seller. Every factory uses inputs. Molecules move randomly & rapidly in relation to each other. Net diffusion is from [high] to [low]. Partial pr. of the gas is proportional to [gas]. .  nitrogen  79% 600 mmHg.  Oxygen  21% 160 mmHg. Which gases will leaves be exchanging?. Gas Exchange in Leaves. What features will gas exchange organs have to maximise the rate of exchange?. Large surface area, short diffusion pathway, concentration gradient. Diffusion is a process of . mass transport. that involves the atomic . or molecular motion. .. In the simplest form, the diffusion can be defined as the . random walk. of an ensemble of particles from regions of high concentration to regions of lower concentration. An Example . .
