Tull - wannan ... A definition, misalai da siffofin da Physiology

Ganin jikin algae, shi za a iya zaci cewa shi ne tsarin da ganye da kuma kara. A gaskiya shi ne ba. Yana da wani thallium. Wannan musamman tsarin. Shi ne halayyar da ƙananan tsire-tsire, fungi da lichens.

Tull - shi ...

Tull ma kira thallus ko Slano. Abin da ke bambanta shi daga tsere? The abu ne cewa, thallium - a tsarin kafa unspecialized Kwayoyin. Su suna da alaka ne kawai anatomically amma kowane aiki a matsayin mai raba mahaluži. Yana ba ya samar da kyallen takarda, Saboda haka da hukumomi. Ina da wani tushen da kuma fronds. Its ayyuka suna yi da rhizoids wanda hašawa jiki zuwa substrate.

Sloevischnye kwayoyin

A kwayar algae thallium - wani tsarin da cewa zai iya zama filamentous, juz'i, farantin ko leaf-dimbin yawa. Suna girma ne kawai a ruwa, don haka ba su bukatar wani inji ko a gudanar da kyallen takarda. Su launi dogara a kan irin pigment ne marinjaya a cikin sel. Duk da haka, ko da kuwa wannan hali da suke duk dauke da chlorophyll da suke iya photosynthesis. Mai guda-celled algae ne thallium monadic irin. An halin m siffar da kuma motsi da taimakon flagella. Kadan na kowa ne ƙananan tsire-tsire da amoeboid thallus. Saboda da bakin ciki harsashi iya canja siffar da kuma matsar kusa, forming pseudopodia. Thalli monadic da amoeboid irin na iya zama duka guda-celled da aboki a mazauna.

naman kaza jiki kuma kafa thallus. Ya kunshi mutum filaments - hyphae, da totality of wanda ake kira da mycelium ko mycelium. Wadannan kwayoyin suna ciyar da heterotrophically mamaye hyphae ruwa tare da narkar da na gina jiki. A musamman irin thallus ne yeasts. Sun kunshi mutum Kwayoyin ko kafa na sarƙoƙi iya budding.

lichen thallus

Lichens ne a jam'i na filaments da fungal sel blue-kore algae ko cyanobacteria. Su iri thallus iya foliated, bushy ko crustose. Da farko kama lobed farantin, wanda Forms ƙananan ɓangare na bawo da outgrowths. Suna a haɗe zuwa substrate.

Bushy fronds girma tsaye. Don substrate suna a haɗe ƙananan ɓangare na thallus. Similar a cikin bayyanar da kananan bushes. Crustose lichens da siffar crusts ko adibas na launi daban-daban. Suna haka tam Fused tare da substrate cewa ware su ne kusan ba zai yiwu. Fronds hali mafi girma spore shuke-shuke. Su duba prothallia - bakin ciki kore farantin.

Physiology Features

Tull, duk da wajen m fasali na tsarin, bayar da dukan zama dole matakai na rayuwa. Da taimakon vegetative haifuwa ya auku da kuma sporulation. da thallus Kwayoyin suna chlorophyll. Sun iya zuwa sha kwayoyin halitta daga cikin ƙãre substrate. Amoeboid da flagellate iri thalli motsi.

Fronds wasu kwayoyin iya shiga cikin moriyar co-zama tare da sauran mulkokin yanayi. Alal misali, mycorrhizal fungal hyphae form tare da tushen da mafi girma da shuke-shuke. The aka gyara na lichen thallus kuma amfana daga co-zama. Naman kaza sha monosaccharides, wanda synthesizes da cell algae. A karshen samar da ma'adanai ta wajen hyphae.

Saboda haka, thallium - wani tarin Kwayoyin cewa, samar da jiki na ƙananan kuma mafi girma spore shuke-shuke, fungi da lichens. Wannan tsarin ba ya samar da kyallen takarda da kuma kunshi na musamman Tsarin alaka anatomically.
