Yokuzviparadzanisa Green algae: tsanangudzo pfupi

To musi, girini algae anoonekwa zvikuru zvakawanda boka, iro rine vanenge 20 zviuru marudzi. Izvi zvinosanganisira zvose zvinenge kuroorwa-celled, uye ichitongwa siyana, uyewo miti pamwe zvipuka zvine masero akawanda thallus huru. Pane Vamiririri kuti kurarama mumvura (munyu uye yakachena) uyewo zvinenge dzakashandisa kurarama munyika iri nyorova ezvinhu.

The chikuru chinoratidza boka iri avo ruvara zano - nokuti zvose zvamarudzi mamirire zvakasvibirira kana greenish-yellow ruvara. Izvi imhaka huru ruvara masero - chlorophyll.

Sezvambotaurwa, kuti dhipatimendi rinobatanidza vamiririri akasiyana zvachose. Kune unicellular uye ichitongwa siyana, uyewo zvipuka zvine masero akawanda zvinenge huru, kusiyaniswa thallus. Vamwe vamiririri unicellular kufamba kushandisa flagella, zvipuka zvine masero akawanda, kazhinji kuda pasi kana kurarama mumvura mbiru.

Kunyange paine zvinenge chinhu masero, ruzhinji nhaka foni rusvingo. The chikuru STRUCTURAL chezvinonhuwira sero madziro cellulose, izvo, sezvinei, inokoshesa enderana noruzhinji.

The nhamba, ukuru uye Maumbirwe chloroplasts muchitokisi angava akasiyana zvichienderana norudzi chirimwa. The chikuru ruvara iri chlorophyll, kunyanya, mumwe, uye, b fomu. Kana carotenoids ari plastids raiva kunyanya Beta-carotene uye lutein, uyewo uwandu neosantina diki, zeaxanthin uye violaxanthin. Sezvineiwo, masero mamwe zvipenyu vane zvikuru yero kana orenji ruvara - izvi imhaka kuunganidza carotenoids ndiyo chloroplast.

Vamwe chete-celled girini algae vane chaiyo yakarongeka - ziso kuti anoonawo kubatidza rwedenga uye girini chakarondedzera.

The chikuru chigadzirwa rine starch granules izvo aive runonyanya ari plastids. Shomanana vamiririri murayiro yokutsiva zvinhu zviri iiswe cytoplasm.

Department Green algae: nzira maberekero

Kutaura zvazviri, kuti vamiririri boka iri vanoonekwa ne Munenge zvose zvinobvira nzira kubereka. Vegetative kubereka kunogona kuitika nenzira muchitokisi nokupesana (unicellular vamiririri pasina muchitokisi rusvingo), kusabatana thallus (Nzira Iri maitire zvipuka zvine masero akawanda uye ichitongwa siyana). Mune dzimwe mhando chaizvo nodules vari aumba.

Asexual kubereka iri anomiririrwa anotevera siyana:

• zoospores - flagella masero vaikwanisa vanoshingaira kufamba;
• aplanospory - hatina zvakadaro nharo flagellar midziyo, asi zvakangonyuka zvakanaka contractile vacuole; masero havagoni basa kufamba;
• autospores - ichi mhando nharo kwakabatana zvikurukuru kwadzakabva zvakatipoteredza. In chimiro ichi, muviri anogona kumirira kubva yakaoma, uye vamwe nematambudziko ezvinhu.

Sexual kubereka zvinogonawo dzaisiyana - nayo oogamy uye heterogamy uye hologamiya uye isogamy uye conjugation.

Yokuzviparadzanisa Green algae: characterization vamwe vamiririri

boka iri zvinosanganisira zvakawanda inonyatsozivikanwa vamiririri chirimwa nyika. Somuenzaniso, chimwe-celled algae Spirogyra uye Chlorella zvinosanganisirwawo mu kukupfura.

Chlamydomonas - nokururamisira rinozivikanwa genus ouswa algae, zvinova ndizvo hunobatsira kukosha. boka iri zvinosanganisira unicellular zvinenge uye hombe dzvuku ziso chromatophores, rine pigments. It chlamydomonas zvinokonzera "vachiita" mvura reservoirs, madziva uye aquariums. In pamberi chezuva Organic zvinhu zvinoberekwa photosynthesis. Zvisinei, muviri uyu anogona kudzidza kuvenga zvinhu kubva kwokunze kwezvakatipoteredza. Naizvozvo Chlamydomonas aiwanzoshandisa mvura yokunatsa.
