Movement in plants is an infiltration of the stimulus (stimulus) whether originating from inside or outside of the individual. So the emergence of movement in plants was evidence of irritability.
Based on the presence or absence of stimulation, movement in plants can be divided into:
Endonom motion is motion that is not influenced by external factors. An example is motion in the cell cytoplasm.
Etionom motion is motion that is influenced by stimuli from the outside. examples of stimuli from the outside is light, temperature, gravity, etc..
Higrokopis motion is motion caused by the decrease of water content on an ongoing basis, so that the seeds, fruit, or a crack sporangium
Motion EtionomNasty
Nasty parts of the plant is moving toward its motion was not influenced by the direction of the stimulus. Nasty motion caused by changes in bone tissue turgor in the leaf. Based on the type of stimulation, nasty divided into several types, such as below:
Seismonasti or tigmonasti a nasty motion that occurs due to a touch stimulus. An example is the motion to close leaves embarrassed daughter (Mimosa pudica) when touched.
Niktinasti the movement sleep legumes leaves late in the afternoon due to changes in turgor pressure on petiole.
Termonasti a nasty motion caused by temperature stimuli. Examples of tulips blooming when temperatures rise.
Fotonasti namely that nasty motion stimulation in the form of light source, such as flower blooming at four o'clock (Mirabilis jalapa)
Complex is a nasty nasty motion caused more than one stimulus. For example the motion to open and close the stomata.
Tropism
Tropism is a plant that the direction of motion is influenced by the direction of motion stimuli. Positive tropism is approaching its direction of motion stimuli, while negative tropism is the direction of motion away from the stimulus. Based on the type of stimulation, tropism can be divided into several kinds, such as below:
Geotropisme or gravitropisme a tropism motion stimulation caused the Earth's gravity. There are two geotropisme Geotropisme namely positive and negative geotropisme. Is positive Geotropisme plant organ motion in the direction of gravity, for example movement of plant roots. While the negative geotropisme is motion in the opposite direction of earth gravity, for example movement grow stem plant.
Fototropisme a tropism motion caused by the influence of light stimulation. Fototropisme is two fototropisme fototropisme positive and negative. In general, above-ground plant parts are fototropisme roots are positive and negative fototropisme
Tigmotropisme a tropism motion caused by touch stimuli. In general, occur in plants tigmotropisme climbers such as grapes, sweet potatoes, melons, and other climbing plants.
Hidroptropisme motion tropism is caused by stimulation of water. For example movement of root growth into the water.
Termotropisme a tropism motion caused by temperature stimuli.
Kemotropisme a tropism motion caused by chemical stimulation. Examples roots movement toward fertilizer.
Reotropisme motion tropism is caused by water flow and thus affects the direction of movement of plants. Examples of water hyacinth.
Taksis
Taksis is motion that occurs due to external stimuli. The entire plant body will move, and the direction of motion is determined by the direction of stimulation. Based on the type of stimulation, taksis divided into several types, such as below:
Fototaksis is taksis motion caused by light stimulation. eg Euglena motion towards the light. Fototaksis fototaksis divided into positive and negative fototaksis. Positive Fototaksis plant is motion near the light stimulus, whereas negative fototaksis plant is moving away from the stimulus of light.
Kemotaksis is taksis motion caused by chemical stimulation. For example spermatozoid cell movement toward the egg.
Galvanotaksis is taksis motion caused by electrical stimulation.
