A tropism yog ib txoj kev loj hlob mus rau los yog deb ntawm ib kev txhawb zog . Feem ntau stimuli uas cuam tshuam cov nroj tsuag loj hlob xws li lub teeb, lub ntiajteb txawj nqus, dej, thiab kov. Nroj tsuag tropisms txawv ntawm lwm yam kev txhawb zog generated txav, xws li nastic taw, nyob rau hauv hais tias cov kev taw qhia ntawm cov lus teb nyob rau hauv cov kev taw qhia ntawm lub kev txhawb zog.

Tsuas yog li ntawd, 4 hom Tropisms yog dab tsi?

Cov ntaub ntawv ntawm tropism muaj xws li phototropism (teb rau lub teeb), geotropism (teb rau lub ntiajteb txawj nqus), chemotropism (teb rau tej yam khoom), hydrotropism (teb rau dej), thigmotropism (teb rau mechanical stimulation), traumatotropism (teb rau qhov txhab txhab), thiab galvanotropism, los yog electrotropism (teb

Ib tug kuj yuav nug, cov stimuli ua li cas cov nroj tsuag teb rau? Nroj tsuag paub tias yuav teb rau ntau qhov stimuli sab nraud zoo li teeb , lub ntiajteb txawj nqus, kov, tshuaj lom neeg, thiab lwm yam. Cov nroj tsuag teb rau sab nraud nrog kev pab ntawm receptors thiab cov tshuaj hormones. Cov receptors pab cov nroj tsuag kom nkag siab txog kev txhawb nqa sab nraud thiab ua raws li. Lawv tswj kev loj hlob ntawm cov nroj tsuag teb rau teeb.

Hais txog qhov no, 3 hom Tropisms yog dab tsi?

Thaum lub zog txav mus rau qhov stimulus, nws yog hu ua zoo tropism. Ib yam li ntawd, thaum lub zog txav deb ntawm qhov stimulus, nws yog hu ua negative tropism. Thaum muaj ntau hom tropism, peb tsuas yog tsom rau peb hom tseem ceeb: phototropism , geotropism thiab thigmatropism.

Cov piv txwv ntawm Tropisms yog dab tsi?

Qee qhov piv txwv ntawm tropisms suav nrog gravitropism (teb rau lub ntiajteb txawj nqus), hydrotropism (teb rau dej), thigmotropism (teb rau kov), thiab phototropism (teb rau lub teeb). Cov no tropisms tseem ceeb heev rau cov nroj tsuag ciaj sia.
