Yog li nws yog cov lus teb tsis yog kev taw qhia uas tsis cuam tshuam los ntawm kev coj ua ntawm kev txhawb nqa.
Daim duab 02: Thigmonasty
Ntxiv mus, cov lus teb thigmonastic feem ntau yog vim muaj kev hloov pauv hauv turgor siab hauv cov hlwb es tsis yog qhov txav los ntawm cov nroj tsuag loj hlob.

Dab tsi zoo sib xws ntawm Thigmotropism thiab Thigmonasty?
Thigmotropism thiab thigmonasty yog ob hom kev sib txawv ntawm cov nroj tsuag txav uas pom los ntawm cov nroj tsuag hauv kev teb rau qhov stimulus kov
Qhov txawv ntawm Thigmotropism thiab Thigmonasty yog dab tsi?
Thigmotropism yog kev taw qhia ntawm cov nroj tsuag hauv kev teb rau qhov kev txhawb nqa ntawm kev kov. Nyob rau hauv sib piv, thigmonasty yog ib tug tsis-directional txav ntawm cov nroj tsuag nyob rau hauv teb rau stimulus ntawm kov. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm thigmotropism thiab thigmonasty. Ntxiv mus, cov kev taw qhia ntawm thigmotropic teb nyob ntawm qhov kev taw qhia ntawm stimulus, thaum cov kev taw qhia ntawm thigmonastic zog yog ywj siab ntawm lub stimulus txoj hauj lwm. Yog li, qhov no kuj yog qhov sib txawv ntawm thigmotropism thiab thigmonasty.
Lwm qhov sib txawv ntawm thigmotropism thiab thigmonasty yog tias thigmotropism tshwm sim raws li qhov kev txhawb nqa ntawm kev loj hlob hauv cov cheeb tsam ntawm cov nroj tsuag thaum thigmonasty feem ntau cuam tshuam nrog kev hloov pauv hauv turgor siab hauv cov hlwb ntau dua li kev loj hlob. Thaum xav txog cov piv txwv, coiling ntawm cov nroj tsuag tendrils nyob ib ncig ntawm cov khoom nto thiab kev loj hlob ntawm cov hauv paus hniav hauv av yog ob qho piv txwv rau thigmotropism thaum kaw ntawm Mimosa pudica nplooj thiab kaw ntawm venus ya-trap yog ob qho piv txwv rau thigmonasty.
Summary – Thigmotropism vs Thigmonasty
Thigmotropism thiab thigmonasty yog ob hom lus teb rau qhov kev txhawb nqa. Qhov sib txawv tseem ceeb ntawm thigmotropism thiab thigmonasty yog tias thigmotropism yog cov lus teb rau kev kov thaum thigmonasty tsis muaj kev ywj pheej ntawm kev taw qhia ntawm qhov kov. Ntxiv mus, thigmotropism tshwm sim los ntawm kev loj hlob teb thaum thigmonasty tshwm sim vim kev hloov pauv hauv turgor siab nyob rau hauv lub hlwb es tsis yog kev loj hlob.
