Tuesday, April 2, 2013 MOVEMENT IN PLANT

• 2. • Based on its stimulus, the movements in plant are grouped into three : 1. HYGROSCOPIC MOVEMENT 2. ENDOGENOUS MOVEMENT 3. EXOGENOUS MOVEMENT /ETIONOM
• 3. 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)  the opening of sporangium in fern as the cause of wrinkling annulus cells
• 4. ANULUS
• 5. The opening of sporangium of moss as the causeof the wrinkling peristome cells
• 6. 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 velocity
• 7. EXOGENOUS MOVEMENT (etionom/esionom)• Is plant movement that it is caused by external stimulus• External stimulus such as : Light, gravity, water, touch, and chemical substance
• 8. The various kinds of exogenous movements in plants1. Tropism movement2. Nastic movement3. Taxis movement
• 9. 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. hydrotropism
• 10. 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 light
• 11. 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 upward
• 12. GEOTROPISM
• 13. CHEMOTROPISM• Is tropism movement that is caused by chemical substances stimulus• Example :  the movement of root to food/fertilizer substance in soil
• 14. THIGMOTROPISM• Is tropism movement that is caused by stimulus of touch to harder thing• Example  Tendril of plant movement
• 15. HYDROTROPISM• Is the movement of plant root that is influenced by reservation of soil water.
• 16. 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 nasty
• 17. PHOTONASTIC• Is nasty movement that its caused by stimulus of light• example  the opening of Mirabilis jalapa flower at certain time
• 18. 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 night
• 19. THIGMONASTY/seismonasty• Is nasty movement that it’s caused by stimulus of touch• Example  the closing of leaves of Mimosa pudica when touched
• 20. THERMONASTY• Is nasty movement that is caused by temperature stimulus• Example  Tulip flower will bloom if suddently get temperature increasement
• 21. 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 water
• 22. Picture The Opening And Closing Of Stomata
• 23. 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. chemotaxis
• 24. 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 light
• 25. 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 archegonium
