Qhov sib txawv tseem ceeb ntawm heliophytes thiab sciophytes yog tias heliophytes xav tau kev siv lub teeb kom loj hlob thaum sciophytes xav tau lub teeb qis kom loj hlob.
Lub teeb yog qhov tseem ceeb cuam tshuam ncaj qha rau kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag thiab kom muaj sia nyob. Lub teeb yog koom nrog cov txheej txheem sib txawv raws li cov nroj tsuag physiological thiab biological txheej txheem, xws li kev tsim cov chlorophyll, transpiration rate, stomatal txav, thiab cog kev faib tawm. Heliophytes thiab sciophytes yog ob hom nroj tsuag uas txawv raws li lawv cov ntsiab lus them lub teeb.
Heliophytes yog dab tsi?
Heliophytes yog cov nroj tsuag hnub ci, thiab lawv hloov mus rau qhov chaw nyob nrog lub hnub ci hluav taws xob hnyav heev vim lawv tus kheej cov qauv thiab cov metabolism. Cov nroj tsuag no muaj nyob rau hauv pob zeb, meadows, roob pastures, qhib struts, thiab grasslands, uas raug rau lub hnub. Ob peb piv txwv ntawm cov nroj tsuag no yog mint, thyme, dawb clover, roses, ling, mullein, thiab mos velcro.
Daim duab 01: Heliophytes
Ib qho tshwj xeeb ntawm heliophytes yog qhov muaj cov nplooj me me nrog cov quav nyab thiab cov plaub hau tiv thaiv. Cov txheej txheem no tiv thaiv lub teeb hluav taws xob ntau dhau thiab poob dej. Cov qauv ntawm nplooj feem ntau txawv nrog ob txheej palisade. Chloroplasts ntawm heliophytes muaj cov khoom tiv thaiv xws li carotenoids, enzymes, thiab reactive oxygen hom kom tsis txhob muaj cov tshuaj lom. Ib lub stoma thiab ntsuab tua kuj muaj nyob rau ntawm nplooj los pab txhawb kev sib pauv roj. Cov no kuj pab kom muaj peev xwm ntawm photosynthesis. Heliophytes kuj tseem muaj lub teeb pom kev zoo. Cov yam ntxwv no yuav tsum muaj kev siv lub teeb pom kev zoo dua rau kev hloov pauv ntawm cov pa roj carbon dioxide. Tsis tas li ntawd, nplooj ntawm heliophytes muaj ntau dua basal metabolism thaum piv rau lwm nplooj.
Sciophytes yog dab tsi?
Sciophytes yog hom nroj tsuag uas yuav tsum tau them nyiaj qis dua. Yog li ntawd, lawv hu ua ntxoov ntxoo-hlub ntoo los yog ntxoov ntxoo nroj tsuag. Lawv muaj loj photosynthetic units. Lawv ncav cuag lawv qhov saturation thaum raug 20% ntawm tshav ntuj. Sciophytes muaj peev xwm hloov kho kom txo lub teeb siv los yog ib nrab hnub. Qee qhov piv txwv ntawm sciophytes suav nrog kua txob dub, cacao, kas fes, thiab qhiav.
Daim duab 02: Sciophytes
Sciophytes feem ntau loj hlob hauv qhov ntxoov ntxoo thiab muaj cov nplooj nyias nyias nrog thaj chaw ntau dua. Cov nplooj muaj chlorophyll ntau dua li cov nroj tsuag uas tau txais lub hnub ci tag nrho vim tias cov nplooj ntoo muaj txiaj ntsig zoo. Qhov no tso cai rau cov nroj tsuag sau hnub ci ntawm cov teeb pom kev tsawg. Sciophytes suav nrog ntau tus yam ntxwv los siv lub zog muaj zog thiab kev txuag hluav taws xob. Cov yam ntxwv zoo li no suav nrog cov nplooj nyias nyias nrog cov ntsiab lus chlorophyll ntau dua hauv ib chav tsev ntim, cov kab mob epidermal uas muaj lub ntsej muag lub ntsej muag kom pom lub hnub ci tuaj rau hauv cov hlwb mesophyll, nqaim stems nrog ntev internodes, nyias cuticles, thiab muaj stomata ntawm ob qhov chaw., zoo-tsim spongy parenchyma, thiab ntoo nrog tsawg ceg.
Dab tsi yog qhov zoo sib xws ntawm Heliophytes thiab Sciophytes?
- Heliophytes thiab sciophytes yog ob hom nroj tsuag categorized raws li qhov xav tau ntawm lub teeb.
- Ob leeg heliophytes thiab sciophytes muaj kev txhim kho stomatal.
Qhov txawv ntawm Heliophytes thiab Sciophytes yog dab tsi?
Heliophytes xav tau kev siv lub teeb rau kev loj hlob, thaum sciophytes xav tau qis siv lub teeb rau kev loj hlob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm heliophytes thiab sciophytes. Heliophytes muaj tsawg tsim spongy parenchyma thiab tsim ntau palisade parenchyma. Sciophytes muaj ntau dua spongy parenchyma thiab tsis tshua tsim palisade parenchyma. Ntxiv mus, heliophytes muaj ntau flowering thiab fruiting, thaum sciophytes muaj tsawg flowering thiab fruiting.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm heliophytes thiab sciophytes hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Heliophytes vs Sciophytes
Lub teeb yog qhov tseem ceeb hauv kev loj hlob, kev loj hlob, thiab kev muaj sia nyob ntawm cov nroj tsuag. Heliophytes thiab sciophytes yog ob hom nroj tsuag raws li lawv lub teeb xav tau rau kev loj hlob. Heliophytes xav tau kev siv lub teeb kom loj hlob, thaum sciophytes xav tau lub teeb qis kom loj hlob. Tsis tas li ntawd, heliophytes muaj tsawg tsim spongy parenchyma thiab tsim ntau palisade parenchyma. Nyob rau hauv sib piv, sciophytes muaj ntau tsim spongy parenchyma thiab tsawg tsim palisade parenchyma. Tsis tas li ntawd, heliophytes tau txais ntau paj thiab fruiting, thaum sciophytes undergo tsawg flowering thiab fruiting. Yog li, qhov no qhia txog qhov sib txawv ntawm heliophytes thiab sciophytes.
