ENDOGENOUS MOVEMENT 3. EXOGENOUS MOVEMENT /ETIONOMHYGROSCOPIC MOVEMENT: HYGROSCOPIC MOVEMENT Is movement of part of plant that is caused by the influence of the change of water level from its cells so happens non-homogenous wrinkling Example the breaking of dried Calanchoe pinnata fruit ( pacar air) t he opening of sporangium in fern as the cause of wrinkling annulus cellsPowerPoint Presentation: ANULUSThe opening of sporangium of moss as the cause of the wrinkling peristome cells: The opening of sporangium of moss as the cause of the wrinkling peristome cellsENDOGENOUS MOVEMENT (autonomic): ENDOGENOUS MOVEMENT (autonomic) Is movement that is not known yet its cause certainly but predicted this motion is caused by stimulus that comes from the body of plant itself . Examples the flowing movement of cytoplasm in cell the bending movement of leaf bid because of difference of growth velocityEXOGENOUS MOVEMENT (etionom/esionom): EXOGENOUS MOVEMENT ( etionom / esionom ) Is plant movement that it is caused by external stimulus External stimulus such as : Light, gravity, water, touch, and chemical substanceThe various kinds of exogenous movements in plants: The various kinds of exogenous movements in plants Tropism movement Nastic movement Taxis movementTROPISM MOVEMENT: TROPISM MOVEMENT Is movement of part of plant to stimulus that is movement direction is determined by the stimulus Kinds of tropism 1. phototropism 2. geotropism 3. chemotropism 4. thigmotropism 5. hydrotropismPHOTOTROPISM: PHOTOTROPISM Is tropism movement that caused by stimulus of light Examples the tip of plant that lies in room will bend to direction of incident lightGEOTROPISM: GEOTROPISM Is tropism movement that follows earth gravitational force positive geotropism is geotropism movement that its direction is downward Negative geotropism is geotropism movement that its direction upwardGEOTROPISM: GEOTROPISMCHEMOTROPISM: CHEMOTROPISM Is tropism movement that is caused by chemical substances stimulus Example : the movement of root to food/fertilizer substance in soilTHIGMOTROPISM : THIGMOTROPISM Is tropism movement that is caused by stimulus of touch to harder thing Example Tendril of plant movementHYDROTROPISM: HYDROTROPISM Is the movement of plant root that is influenced by reservation of soil water.NASTIC MOVEMENT: NASTIC MOVEMENT Is plant movement to stimulus, that its direction is not determined by stimulus but by plant itself Kind of nastic movement 1. photonasty 2. nictinasty 3. thigmonasty 4. thermonasty 5. complex nastyPHOTONASTIC: PHOTONASTIC Is nasty movement that its caused by stimulus of light example the opening of Mirabilis jalapa flower at certain timeNICTINASTY: NICTINASTY Is nasty movement that its caused by dark condition (sleeping movement ) Examples the closing of Butterfly flower ‘s leaves at night the closing of compound leaves of Leucaena glauca at nightTHIGMONASTY/seismonasty: THIGMONASTY/ seismonasty Is nasty movement that it ’ s caused by st i mulus of touch Example the closing of leaves of Mimosa pudica when touchedTHERMONASTY: THERMONASTY Is nasty movement that is caused by temperature stimulus Example Tulip flower will develop if suddently get temperature increasementCOMPLEX NASTY: COMPLEX NASTY Is nasty movement that is caused by several factors altogether Example the opening and closing of stomata is influenced by light, chemical substance and waterPicture The Opening And Closing Of Stomata: Picture The Opening And Closing Of StomataTAXIS MOVEMENT: TAXIS MOVEMENT Is transfer movement of all part of plant to stimulus that its direction is determined by the stimulus Kinds of taxis movement 1. phototaxis 2. chemotaxisPHOTOTAXIS: PHOTOTAXIS Is taxis movement that is caused by stimulus of light Example the movement of chlorophyll to surface/nearer surface the leaves to get the lightCHEMOTAXIS: CHEMOTAXIS Is the taxis movement that is caused by chemical substances stimulus . Example movement of spermatozoid of moss and fern to ovum that is found in archegonium attracted to the sugar or protein that is produced by archegoniumPowerPoint Presentation: THE ENDPowerPoint Presentation: Do The Exercise Chapter 8 Page 199 – 200 Multiple Choices and Essay Just The Answers Do on your notebookPowerPoint Presentation: Created by Alfie_MSK, A Biology teacher of GIS JH You can also download this slide on http://www.slideshare.net/alfikesturi Or on http://www.authorstream.com/kesturi You do not have the permission to view this presentation.
