Kwecala Green ulwelwe: inkcazelo emfutshane

Ukuza kuthi ga ngoku, ulele eluhlaza kugqalwa iqela elikhulu, nto leyo eye iintlobo ezimalunga nama-20 amawaka. Ezi ziquka zombini elilodwa olunye, kunye neefom colonial, kwakunye nezityalo multicellular thallus ezinkulu. Kukho abameli ezihlala emanzini (amtyuba namnandi) kwakunye eziphilayo apha naphaya ukuze baphile kumhlaba kwiimeko efumileyo.

ISebe Green ulwelwe: inkcazelo emfutshane

Eyona iphambili yale qela iqhinga labo umbala - kuzo zonke iintlobo umbala oluhlaza okanye zana-yellow isici. Oku kungenxa yokuba iiseli eziphambili ebala - yiklorofili.

Njengoko sele kukhankanyiwe, isebe idibanisa abameli ezahlukeneyo ngokupheleleyo. Kukho iintlobo kwiseli enye kwaye colonial, kwakunye eziphilayo multicellular kunye esikhulu, thallus umohluko. Abanye abameli kwiseli ukuhamba usebenzisa misila, multicellular, ngokuqhelekileyo incamathele emazantsi okanye uhlala kwikholam emanzini.

Nangona kukho izinto kunye iiseli ezingenanto, uninzi ilifa udonga iseli. Icandelo engundoqo noshowo udonga lweeseli luvulekile kwincindi, leyo, ngokuzenzekelayo, kugqalwa ebalulekileyo ngendlela iimpawu.

Inani, ubukhulu kunye nokumila chloroplasts kule seli inokuba nomahluko ngokuxhomekeke kuhlobo lwesityalo. Kombala eziphambili yiklorofili, ngokukodwa, a kunye nefomu b. Ke carotenoids kwi plastids eziqulathwe ikakhulu beta-carotene kunye lutein, kwakunye neentwana neosantina, zeaxanthin kunye violaxanthin. Okubangel 'umdla kukuba, iiseli ezinye eziphilayo ezi yellow kakhulu okanye naorenji ngombala - oku kubangelwa beqokelela carotenoids nguye chloroplast.

Abanye ulwelwe eluhlaza ezineseli enye babe isakhiwo esithile - iliso esihoyana ukukhanyisa spectrum ngemisonto eluhlaza.

Imveliso esisiseko kukho granules starch leyo ziqulethwe ubukhulu becala kwi plastids. Kuphela nje ngabameli embalwa izinto ukuze replacement ezifakwe kukho icytoplasm.

ISebe Green ulwelwe: iindlela lweenkomo

Enyanisweni, ukuba abameli eli qela luphawulwa phantse zonke iindlela kunokwenzeka yokuzala. ukuzala kwezityalo lungavela division iseli (abameli kwiseli enye ngaphandle iseli eludongeni), ukuqhekezwa thallus (Le ndlela uphawu iintlobo multicellular kunye colonial). Kwezinye iintlobo maqhuqhuva ezithile kwakheka.

ukuzala maqanda nto imelwe yi ezi fom zilandelayo:

• zoospores - iiseli misila ekwaziyo intshukumo esebenzayo;
• aplanospory - abanakho izixhobo imbambano flagellar, kodwa aphuhliswe kakuhle contractile vacuole; iiseli bangazikisiyo intshukumo esebenzayo;
• autospores - olu hlobo ukungavisisani kuphathelene ngokuyintloko kukhubazeko kokusingqongileyo. Kule fomu, umzimba ungakwazi ukulinda ilizwe owomileyo, kunye nezinye iimeko ezinzima.

ukuzala kwakhona zinokohluka - oko oogamy kunye heterogamy kunye hologamiya kunye isogamy kunye conjugation.

Kwecala Green ulwelwe: abalinganiswa kwezinye abameli

Eli qela libandakanya abameli ezininzi ezaziwayo-kakuhle kwihlabathi izityalo. Umzekelo, ulele ezineseli enye Spirogyra kunye Chlorella nazo zibandakanyiwe squad.

Chlamydomonas - ngobulungisa ezaziwayo-kakuhle uhlobo lwe ulwelwe eluhlaza, nto leyo ebaluleke pfunaka. Eli qela libandakanya kwiseli kunye chromatophores enkulu iliso ebomvu, equlethe zombala. It chlamydomonas izinto "eqhubela" ezigcina amanzi, amadama kunye akwariyam. Phambi kwezinto kwelanga eziphilayo eziveliswa photosynthesis. Noko ke, le ephilayo ukubamba izinto ukusuka kwindawo lwangaphandle. Ngoko Chlamydomonas wayedla zokuhlanjululwa amanzi.
