Sei miti photosynthesize

ari miti uye miti zvinoda kufukidza zvakakwana goko repasi, chete pamatanda ndipo patinganetse kuwana. Kutenda kwavari, hupenyu hwepanyika hunogona kuvapo, nekuti mhuka dzinovimba neoksijeni yavanodzinga nemashizha avo. Asi isu tinovabatsirawo, nekudzinga carbon dioxide yavanoshandisa kugadzira glucose… uye oxygen. Nekudaro, zvinogona kutaurwa kuti kutenderera kwapera, kunyangwe chokwadi chiri icho miriwo yakaonekwa kare pamberi pemhuka 🙂.

Pakati pavo vese, imwe yeiyo yakwezva yakanyanya kutariswa ndeayo arboreal iwo. Iwe unoziva here kuti miti photosynthesize? Kwete? Tinokutsanangurira iwe.

Chii chinonzi photosynthesis?

Photosynthesis inzira yekugadzira chikafu nezvirimwa zvese. Kuti vazviite ivo vanoda chlorophyll, inova yakasvibira chinhu irimo mumashizha. Chlorophyll inobata mwenje wezuva, uyo, pamwe chete necarbon dioxide, unokwanisa kushandura mbishi (mvura nemamineral salts ayo midzi inotora kubva pasi) kana kuita muto wakagadzirwa. Mumwe wemhedzisiro yemaitiro aya, kunze kwekukura kwechirimwa, ndiyo okisijeni iyo mashizha anoburitsa.

Asi sekuziva kwedu, kune miti iyo mune mimwe mwaka (inogona kunge iri chirimo kana vachigara munzvimbo dzakaoma uye dzinopisa, kana mumatsutso-mwaka wechando kana vachigara munzvimbo dzinotonhora zvakanyanya) isina mashizha. Vano photosynthesize futi? Kwete vanogona `t. Pakati pemwedzi iyi vanozorarama nehutano hwavakachengeta kwegore rese.

Miti inodonhedza photosynthesize munguva yechando?

Miti inodonhedza, ndiko kuti, iwo anopera mashizha pane imwe nguva yegore, akakwanisa kuramba ari mupenyu panguva yekukura kwakanyanya. Sei? Zvakanaka, zvinoitika kuti mutangi pamwe nematavi ane pores akasarudzika, anonzi lenticel.

Izvi zvakagadzirwa nemucheka wakasviba, uye ndivo vane basa rekutsinhana kwemhepo yemuchadenga uye nemukati mechikamu. Kuburikidza navo, miti inodonha inogona kufema uye kudikitira, uye nekudaro inopona. Kana iwe uchida kuziva zvakawanda nezvenyaya iyi, tinya apa:

Maruva Anochekera Sei Zvirimwa Muchando

Zvikamu zvephotosynthesis

Photosynthesis inzira inopfuura nematanho maviri, ari iwo anonzi mwenje uye nhanho dzerima:

Bvisa nhanho

Zvinoitika apo mwenje unorova mashizha, kunyanya kune iyo pigment iyo yatinoziva seklorophyll. Mushure mekuteedzana kwekushanduka kwemakemikari, simba iri rinoshandurwa kuita ATP neNADPH enzymes, iyo inozoshandiswa mudanho rerima. Uye zvakare, mamorekuru emvura anoputsa kuburitsa oxygen.

Nerima danho

Panguva ino, inonzi zvakare Calvin-Benson Cycle, zvigadzirwa zvakawanikwa mune yakajeka nhanho yakawedzerwa kune carbon dioxide (CO2) zvinoshandiswa kuwana makabhohaidhiretsindiko kuti, chikafu chezvirimwa.

Iine zita iri nekuti rinowanzoitika husiku, asi kana pakajeka nhanho vatakuri vemagetsi vasipo, zvinongoitika masikati chete.

Photosynthesis yenyika mepu

Pamepu ino unogona kuona kuti 'girini' imba yedu sei, iro Nyika. Sezvauri kuona, kunewo zvirimwa zvirimo mumakungwa: algae uye phytoplankton. Zvinoshamisa, handizvo here? Vanhu vanovimba navo kuti vararame, asi kana tikaramba tichipisa masango nekusvibisa makungwa, hapana chatichasara.

Masango mapapu echokwadi epasi here?

Zvinotaurwa zvakawanda kuti nzvimbo dzakaita senzvimbo inonaya mvura yeAmazon kana masango eArctic ndiwo mapapu epasi, asi ichokwadi sei ichocho? Kunyangwe zvakaoma kutenda, kwete zvakawanda. Zvinoenderana ne kudzidza, masango anonaya anongoburitsa 28% yeo oxygen paPasi. Iyo yakawanda, asi kwete, haasi mapapu, asi zvidiki zvidiki zvinoumba phytoplankton, pamwe nealgae uye plankton.

Izvi zvinoburitsa kusvika 70% yeiyo yakakosha uye yakakosha gasi yatinoda kufema. Chimwezve chikonzero chekutarisira makungwa, ndiko kwavanogara.

Iwe wafungei nezvenyaya iyi?
