[ba bteng] Kaba ar pat ka kam kaba kongsan jong u thied ka long ban ring um bad jingbam na ka khyndew na ka bynta u jingthung. Ki thied kiba kham bit ban pynskhem ia u dieng lane uno-uno u jingthung ki long kito kiba ngam jylliew bad kiba don uwei u thiedbah bad bun ki tnat sriem ia ki tnat dieng, kiba ngi ju shem ha u jingthung uba heh met. Ia kine ki jaid thied la khot ki “tap root” (kynnoh tap rut) ha ka ktien phareng. Kine ki thied ki lah ban kyrshan bha ia u dieng na ka jingbeh ka l’er.
Kiwei pat ki jaid thied kiba ngi ju shem ha ki phlang ki long k iba ki khot ha ka ktien Phareng ki ‘fibrous roots’ (kynnoh phaibros rut). Kine kim da khlain bha ia ka ban kyrshan ia u jingthung, bad namarkata ngi shem ia ki ha ki kynja phlang baroh. Teng-teng ki phlang ki pynmih sa kiwei pat ki jaid thied ban kyrshan ia ki, kum ki ‘prop’ lane ‘brace’ (kynnoh bres) roots. Ngi shem ia ki kum ha u riewhadem bad ha kiwei kiwei ki jingthung phlang. Kine ki thied ki mih na ki mat jong u jingthung bad ki pyrshang ban pynpoi ialade haduh ka khyndew khnang ba ki lah ban ai jingkyrshan ia u jingthung. Ki don ki thied kiba ki khot ha ka ktien phareng ki “aerial” roots kum kito kiba mih na ki tnat jong u dieng banian (banyan tree). Kito kiba la poi sha Calcutta bad kiba la leit jngoh ia ka Botanical Garden, nga ngeit, ki la ioh-i ia ki thied jong uta u dieng banian kiba, ynda la iap u metbah, ki kylla long ki nong kyrshan ia u.
Ka kam kaba kongsan jong ki thied dieng ka long khamtam ban ring um bad jingbam na ka bynta u jingthung. Hynrei ia kane ka kam, ym dei ki thied kiba heh kiba leh ia ka, hynrei pynban ki thied kiba rit katta-katta ba ka long kaba shitom ban iohi ia ki. Ia kine ki thied ki khot ki “root hairs” (ki niuh thied) ha ka ktien Phareng. Kine ki thied ki don ha tduh jong ki thied. Donkam ban kynmaw ia kane, namar ha kaba ai um ia ki jingthung, kam donkam ba ka um kan tuid na jan trai jong u jingthung, hynrei kham na jngai jong u ha ki jaka (zones) kiba don kine ki thied shniuh. Kane bunsien kan pyllait ia ki jingthung na kaba iabit jingpang, namar ba ka um kaba iakynduh bad u dieng uba pang kam ioh ban iakynduh bad u jingthung uba koit bakhiah. Lada ki nongpule ki kwah ban ithuh ia kine ki thied shniuh, ki lah ban buh katto-katne sngi ia ki symbai riewhadem ha ka kot shonsia kaba sngem haduh ba kin da mih thied. Kine ki thied shniuh ki long kiba ring um ne jingbam, kumta ba lada kine kim don u jingthung um lah ban ioh um lane jingbam. Haba phut ia uno-uno u jingthung khnang ban thung ia u ha kawei pat ka jaka, donkam ban da leh sumar bha ba kine ki thied shniuh ruh kin sah, lym kumta u jingthung u lah ban ym ioh um ne jingbam ei-ei.
Ki Sla.
Kawei pat ka bynta jong u jingthung kaba donkam eh ka long ka sla. Lehse lah ban ong ba ka sla ka trei ar tylli ki kam kiba donkam eh.
Kawei ka kam ka long ban pynmih noh shabar ia ka um kaba u jingthung u ring da ki thied ha ka khyndew. Nga ngeit ki nongpule ki kynmaw ba ka sla ka don ki thied (vein) kiba sriem ia ki snur thabbawa. Ha kawei ka jaid sla kine ki thied ki i kumba ki iathain (netted); ha kawei pat ka jaid sla kine ki veins ki long lynter-lynter (parallel). Ki sla tympew, ki sla sohpyriam, lane sla sohphoh, bad ki sla jong kiba bun jaid ki jingthung ki don ki thied (vein) kiba long kumta kum ka snur thabawa lane ka jar, ne ka iarong (netted); hynrei ki sla jong ki kynja phlang baroh ki don kine ki sla kiba ki thied (veins) jong ki ki long lynter-lynter (parallel).
Ha kaba kut kine ki thied (veins), bunsien don i kynja khydrop iba ngim lah ban iohi da ki khmat hynrei iba ngi lah da kaba jem ban iohi ia ki da ka iit tyndong kaba ki khot microscope (kynnoh maikroskop). Ia kine ki khyrdop ki khot ha ka ktien phareng ki stomata. Kawei na ki kam jong kine ki khyrdop ka long ban pyllait ia kane ka um, kaba rung sha u dieng ne u jingthung ban mih shabar. Kumta katto-katne na ka um ka kylla jingbam na ka bynta u jingthung, hynrei kaba bun ka mih shabar na kine ki khyrdop, ynda ka la iaid lyngba ia u jingthung bad lyngba ia ki sla, na kine ki thied (veins).
Kawei pat ka kam kaba phylla jong ki sla ka long ba ka shna ia ka jingbam na ka bynta u jingthung. Kane ka long ka kam kaba phylla katta-katta. Ha ka sla baroh, lait satang katto-katne eh, don kaei-re-kaei (substance) kaba jyrngam. Ia kane ki khot ha ka ktien Phareng ka chlorophyll (klorophil). Kane ka klorophil ka long kaei-kaei kaba phylla katta katta. Ka Klorophil ka shim ia ka um, kaba wan lyngba ki thied na ka khyndew, bad ia ka shibynta jong ka I’er kaba ki khot ka carbon-dioxide (kynnoh karbon da oksaid), bad ka khleh lang ia ki baroh ar ban pynlong ka jingbam kaba ki khot stareh (u Purew). Ka karbon daioksaid ka rung ha ki sla na kita ki khyrdop kiba rit kiba don ha ki sla, kiba la batai haneng, bad kiba ki khot ki stomata. Ki briew kiba la ioh jingtip katto katne ki tip shaphang une uba ngi khot u stareh. U stareh u long u bynta uba bun eh ha ki jingthung baroh. Haba dei-badei une u stareh u kylla shini. Kumta ngi shem ia une u stareh ym tang ha ki sla lane ha ka met jong u jingthung ne u dieng, hynrei ngi shem ruh ia u ha ki symbai baroh, ne ha ki soh ne ha i bynta jong ki jingthung kiba don hapoh khyndew, kata kum ha u phan ne u muli Ynda ki sla ki la pynkylla kumta ia ka um bad ia kata ka I’er kaba ngi khot karbon daioksaid sha u stareh lane sha ka shini, kum ha u pai, kane ka jingbam kaba la shna ha ki sla ka iaid noh sha kiwei pat ki bynta jong u jingthung.
Kane ka kam kaba phylla jong ka sla kam lah ban long khlem ka jingiarap jong ka bor kaba ki jingthung ki ioh na ka sngi. Lada ym don ka sngi, ka klorophil hi ka duh noh lada um don ka sngi; bad kumta ki jingthung ki sdang ban stem. Ia kane ka jingtrei kaba phylla jong ka sla ban pyniasoh ia ka um bad ka karbon daioksaid da ka jingiarap jong ka jingshai na ka sngi ki khot ha ka ktien phareng ka Photosynthesis (kynnoh kumba spel).
