How Do They Live, etc - Lecture Notes","Plant physiology explains how plants survive and function by coordinating water and nutrient transport, photosynthesis and respiration, growth and reproduction, and defense against herbivores and pathogens. Plant activity is strongly shaped by environmental conditions such as light, temperature, gravity, and nutrient and water availability, as well as disease. It also outlines characteristic plant activities including seed germination, flowering, stomatal opening/closing, tropisms, and different forms of plant movement, linking these behaviors to internal chemistry and gas exchange.","Plant Physiology  \nWhat kinds of things do plants DO? how do they live, etc  \nplants must  \nfind water and nutrients and transport them to  \nwhere they are needed within the plant  \ncarry out photosynthesis & respiration  \ngrow and reproduce  \nprotect themselves from herbivores & pathogens  \na plant’s ability to do these things is strongly affected by the environment in which it live  \nplants respond to a variety of environmental conditions  \nSome of the most important environmental factors that affect plant activities include:  \n1. Light (photoperiod)  \n2. Temperature  \n3. Gravity  \n4. Nutrient and Water availability  \n5. Disease  \nThe interactions of these environmental factors with the basic functions of a plant result in a variety of activities characteristic of many plant species  \n1. Seed germination  \n2. Growth (stems, roots, leaves, buds, etc)  \n3. Flowering  \n4. opening and closing of stomata  \n5. tropisms (permanent changes in position of plant or parts)  \n5. plant movements (temporary quicker changes in positions)  \n6. “sleep” movements  \nPlant Chemistry  \nPhotosynthesis  \nprobably the most characteristic set of chemical reactions that occur in plants = the manufacture of food,  \nusually sugar, mainly glucose  \nfrom carbon dioxide and water  \nin the presence of chlorophyll  \nPlants: Plant Physiology , Ziser Lecture Notes, 2005 1  \nlight  \nCO2 + H2O   sugar + O 2  \nchlorophyll (glucose)  \nconverts light energy to chemical bond energy  \nthis trapped energy can later be used by the organism for synthesis reactions or other energy requiring activities  \nphotosynthesis requires carbon dioxide & water CO2 enters through stomata or pores water is absorbed through roots  \nthe light sensitive pigment in plants and algae is chlorophyll this chlorophyll is contained with the chloroplasts  \nglucose can serve as a long term energy storage molecule it can also be easily transported throughout plant  \na. Carbon Dioxide  \nstomata must be open  \nanything that causes the stomata to close could affect photosynthesis  \nb. Water  \nmust be continuous supply of water available more difficult in drought areas  \nc. Light  \namount of light affects rate of photosynthesis  \nd. Salts  \nosmotic stress  \nfertilizer burn  \nprevents absorption  \nesp in hot dry areas, irrigation  \nPlants: Plant Physiology , Ziser Lecture Notes, 2005 2  \nGas Exchange & Aerobic Respiration  \nthe two main gasses involved in plant metabolism are oxygen gas and carbon dioxide gas  \ngas exchange and transport in plants is usually a process of simple diffusion  \n􀀡 moving from a higher to a lower concentration  \nplants absorb and release both O2 and CO2 during the processes of photosynthesis and aerobic respiration  \nPhotosynthesis:  \n􀀡plant cells absorb CO2 needed for photosynthesis through the stomata  \n􀀡 O2 is made during photosynthesis and some of it is released through the stomata  \nAerobic Respiration:  \n􀀡plant cells need constant supply of O2 to break down sugars for energy  \n􀀡CO2 is produced during respiration and excess is released through stomata  \nAerobic Respiration  \nproducts of photosynthesis, sugars or starch are broken down as needed for energy to power metabolism  \n􀀡 Aerobic Respiration  \nrequires oxygen to release this energy from the sugars made during photosynthesis  \nphotosynthesis makes some oxygen  \n􀀡 some is released into air through stomata as a waste product  \n􀀡 some is used by leaf cells for respiration  \nadditional oxygen needed by the plant is taken in in several ways:  \na. stomata  \nPlants: Plant Physiology , Ziser Lecture Notes, 2005 3  \nherbaceous plants have stomata on leaves and stems to get O2 in  \nb. lenticels  \nwoody plants have lenticels to get air to stem cells  \nc. pneumatophores  \nsome plants that grow in stagnant water or water logged  \nsoil have specialized structure called pneumatophores to get O 2 to root cells  \nChemical Plant Products  \nPlants produce a large number of chemicals during their normal metabolism:  \n1.
