Muchitokisi rusvingo wayo basa chirimwa muchitokisi basa

Sero rusvingo ine yakaoma uye gobvu ganda iri cytoplasmic membrane. chaikosha Izvi maitire nokuda masero mabhakitiriya, notumwe uye zvirimwa. Kuwedzera kudzivirira masero, anoita dzakaoma goko uye zvimwe zvakafanana zvinokosha mabasa.

Cell rusvingo: Vhuṱanzi

Sero rusvingo muviri mumwe ane nhamba zvinhu. Somuenzaniso, mune utachiona inoitwa chaizvoizvo kuti murein. Sezvineiwo, mashoko kwemabhakitiriya okuva vari rakakamurwa mhando mbiri - giremu-akanaka uye giremu negative - nokuda peculiarities ari vanachandagwinyira casing mamiriro. Izvi anosarudza utetsa yavo nemishonga.

Kana isu nezvazvo sero masvingo notumwe, avo zvikuru zvinoriumba vanoonekwa glucans uye chitin. Asi algae goko anogona kuva siyana polysaccharides - kunyanya shuga uye ayo yeimwe. Sezvineiwo, murwiyo muchitokisi rusvingo algae kunokosha chaizvo taxa. Zvinokosha kuyeuka uye pamusoro boka diatoms, ane vamiririri synthesize rusvingo silica yavo.

Sero rusvingo chirimwa chacho mabasa

Misimboti vanachandagwinyira nemamiriro sero Kamudzira chinonyanya nyore kudzidza muenzaniso zvinomera muchitokisi. Kunyange zvokuimba kudzivirirwa - ichi ndechimwe chezvinhu zvinokosha muchitokisi rusvingo mashandiro, ine rinokosha zvikuru:

• Inopa zvemaziso uye namakemikari kuramba kwamakamuri;
• Rinodzivirira atsamwira kwamakamuri mu hypotonic svikiro;
• Sero rusvingo ndiye Ion exchanger, sezvo voitakura kuburikidza Absorção de Água uye kubudiswa ions;
• anotora chikamu mune chokufambisa kuti makemikari yeimwe.

Structure foni rusvingo

Chirimwa rusvingo rakakamurwa huru nhatu zvinoriumba: pamatanda, chizvaro uye incrusting zvinhu.

chirimwa Sero rusvingo puranga chinoumbwa cellulose. Nokuda paumbwe rehydrogen zvisungo, cellulose mamorekuru vanoumba microfibrils simba izvo Kunyudzwa inokosha fuma, kana chizvaro.

Chizvaro muchitokisi rusvingo anenge 60% yayo yose vakawanda. It anozadza nzvimbo pakati microfibrils, anosika zvisungo simba pakati macromolecules, anopa elasticity uye simba muchitokisi mamiriro. Chikuru chizvaro zvinoriumba vari hemicellulose uye pectin.

• Hemicellulose ari polysaccharide, chimiro chayo rakafanana cellulose, asi pamwe mapfupi uye mapazi-cheni monomers.
• Pectin kureva polysaccharides, asi rwiyo wavo chinosanganisirawo vakasara methyl doro. Nokuda paumbwe kwemakemikari zvisungo pamwe calcium magnesium ions, pectin anotora chikamu paumbwe pakati kwamahwendefa - nzvimbo masero maviri pedyo vari interconnected. Sezvineiwo, vakawanda pectin inowanikwa miti yemichero.

Encrusting zvinhu kakawanda inomiririrwa lignin, izvo zvinoita anenge 30% kubudikidza yakaoma kurema muchitokisi rusvingo.

• Lignin anogona iiswe chinoramba rukoko kana muchimiro yoga zvinhu - Coils, meshes kana mhete. Izvi zvinhu anoita somunhu samende - nayo anobata cellulose fibers pamwe chete. Pamusana lignification, sero masvingo kuwedzera nemishonga uye risingapindi mvura MENE. Panzira, kuti lignin ndiye anokonzera chirimwa lignification.

Kazhinji, chokunze pose sero Kamudzira rakachengetedzwa zvinhu zvakadai cutin, suberin uye wakisi.

Suberin iri rakachengetedzwa iri romukati divi muchitokisi Kamudzira, ichipa suberization rikurumidze. Sero akadaro anova Eriya aitombotyawo zvachose mwando, saka zviri ayo nokukurumidza kufa kunze, uye vakasununguka nzvimbo izere mhepo.

The chikuru basa munhu waxy fuma uye cuticle - ndiko kuti kudzivirira masero kubva chirwere kuzvidzora, uye achidzikisa mvura kwemvura mumatunhu.

Tinogona kutaura kuti sero rusvingo - hunokosha chaizvo chikamu chirimwa muchitokisi, izvo zvinoita zvarakanga kukura.
