Chii stomata: zviri marongerwo uye kushanda

Shizha iri divi chikamu chirimwa, iyo anoita chinokosha basa dzedenga romugove uye gasi exchange. Tinogona Implementation kwezvinhu zvine maatomu akafanana chokuita zvinhu sechivako jira, mumwe unova stomata. Uchibatsirwa dzavo, chirimwa uye kufema, uye mvura runopwa. Ndezvipi stomata, chii hunhu mamiriro avo uye sangano, isu tsanangura zvizere nyaya yedu.

Afemeruke uye photosynthesis mune miti

All zvipenyu, kusanganisira zvinomera, vanokwanisa mweya. Izvi anozivikanwa chokwadi ndiye chinodiwa chokuvapo kwavo. Chaizvoizvo Its uvete Absorção de Água reokisijeni, oxidation kuti makemikari zvinhu uye kupatsanurwa carbon dioxide. Asi yemapuraneti kukosha miti ine pakuita neizvi muitiro - photosynthesis. In ayo pachena, carbon dioxide wefodya uye okisijeni waida zvose zvipenyu zvose, kunoratidzwa. Plants vanokwanisa kuita azvaiitwa vaviri panguva imwe chete pamwe kusiyanisa zvokutamba kunonyanya kukonzerwa basa stomata, vari pamusoro pechiso jira.

The nemamiriro stomata

Chii chinonzi stoma? Zviri mhando pores riri unhani chirimwa rinenge anonzi cuticle. Stomata vari advantageously aiwanzopiwa wokushanda masero bhinzi serin'i. Masvingo avo vanoiswa thickened munzvimbo dzakasiyana. Between masero stomata yaiva stomatal yokutanga. Therethrough kupinda chirimwa masero uye kunze dzinounzwa gaseous dzakasiyana zvinhu. Binary stomatal masero vanokwanisa kuchinja chimiro chavo, mauri kukura musiyano pakati pavo anogona ngazviwedzerwe kana shoma. Izvi zvinoguma murau negasi mukutsinhana kuchinyanya munyika chirimwa.

Zvakakurukurwa kushanda stomata

Kana zvakadaro, chii chiri stomata, tinonzwisisa, ichi ndicho sei kuita uye chii napo, tine asi kudzidza. Guard masero zvinogona kuchinja chimiro zvichienderana uwandu mvura. Kana fuma iyi iri chirimwa zvizhinji, ivo kuzvimba, kuwedzera kukura uye kure mumwe. Stomatal mutswe apo sezvingatarisirwa inowedzera. Muitiro negasi Exchange anova zvikuru. The zvakawandisa mvura iri asunungurwa kuburikidza pakakoromoka, Ipwa, uye chirimwa asingachengeti overheat panguva inopisa mwaka.

Transpiration zvikuru kwazvo inopiwa mberi kuwedzera mhepo tembiricha uye simba mhepo amplification. In nevakomana nyaya, kana unyoro hazvikwani chiito mashandiro akasiyana masero murindi. Vari pedyo vachionana mumwe, uye stomatal mutswe chete anonyangarika, izvo ruchavhiringidza Implementation acho ose kwemvura mvura. Somugumisiro, chirimwa havazotadzi hunyoro ari ezvinhu kwokushaya kwayo.

Location stomata

Sezvambotaurwa, kune stomata - pabutiro uri mupenyu chirimwa tishu mamiriro. Inonzi cuticle. Plant stomata yaiva, kazhinji, pamusoro rezasi divi jira. mhando iyi kudzivirira kubva zvakananga chezuva. Uyewo pane iyi akanakisisa akachengetedzwa kuchengeterwa remvura chirimwa mumasero. Asi kwete mashizha ose akaronga yakatambarara. Somuenzaniso, ari irises ivo rostut vertically. Naizvozvo, kuti stomata anoparadzirwa kumativi ose mashizha.

Zvakasiyana kuna hwemvura zvirimwa. Rezasi chikamu mashizha varege ane stomata. Pashure pezvose, vanonyudzwa zvachose mumvura uye, naizvozvo, havazokwanisi kuita mabasa avo. The stomata of zvirimwa ari mashizha pamusoro. nhamba yavo zvakakwana guru, sapamazuva imwe mativi sendimita kuti jira - kusvikira zvakawanda makumi ezviuru idzodzo dzakadaro.

Plants pasina stomata

Uye zvimwe zvinomera kunyimwa stomata. Somuenzaniso, Elodea mashizha kunyudzwa zvachose mumvura, saka vasingagoni kuzvidzora. Uye kunyange dzaiva stomata uye ipapo, basa mitambo yavo zvaisazobvira. The ndechokuti mvura inoyerera ichipinda pakakoromoka, kunze pasina kupa gasi Exchange rikurumidze.

zvichireva stomata

Stomata dziri mu pakavha rejira, saka dzinonyanya kushanda ndiko muviri ari muviri zvakatipoteredza. Mumwe wavo ari mvura kuti kwemvura kwacho inonzi transpiration. Implementation Its kunokosha chaizvo kuitira kuti zvirimwa regai overheat mu inopisa mwaka, nokuti zvinogona kuita kuti rufu rwavo. Kana kwemvura iri pamamiriro stomata akapotsa arega transpiration, nokudaro tiine anodiwa unyoro.

Asi gymnosperms vane chaiyo urongwa stomata. Ivo tsinga munguva yechando chaiyo nebwe. Naizvozvo, nhengo dzose dhipatimendi ndivo miti yakasvibira zvinomera. Havafaniri kuteura mashizha kuti vazvidzivirire kubva kurasikirwa mwando yakawandisa muchando. Mukusiyana, vose angiosperms kuramba ari nguva ino chete kutiza uye mudzi. Asi mashizha akawa, kuti arege kurasikirwa nerubatsiro mvura muchando. Naizvozvo, Christmas muti "munguva yechando uye muzhizha zvakafanana ruvara."

Ndezvipi stomata, sei kushanda uye kuita mabasa avo, takurukura zvakawanda nezvedzinza. Zvisinei, izvozvo vanofanira kunzi kunze transpiration, naivowo kuva kushandiswa chikwata kuti wedzerai reokisijeni kuti kufema muitiro zvaiita uye pakutengeserana kuti carbon dioxide inobvisa nokuda photosynthesis. Mukuwedzera, stomata vanokwanisa kudzora kusimba zvose azvaiitwa, iyo inobva zvimwewo zvinoitika pasi, uye kunoratidzwa muna kukwanisa kuchinja mune zvose zvipenyu kuti kukurumidza kuchinja mamiriro dzezvakatipoteredza.

Saka, muna chifukidzo jira jira vari dzidzo chaiyo, inonzi stomata. Zvinosanganisira murindi masero binary uye musiyano uri pakati pavo. Nemhaka basa mamiriro ichi vakaitwa chirimwa muviri zvinokosha dzinotsanagura kwemvura dzemvura, photosynthesis uye afemeruke.
