Brown algae: tsananguro pfupi wedhipatimendi

Brown algae vari kusanganiswa boka zvirimwa kurarama kunyanya zvomumvura mumvura. To musi, anozivikanwa mhando masere chete, izvo mukufamba shanduka vakatamira Freshwater runyararo.

Department Kelp: chivakwa muviri

Nhengo dzose dhipatimendi ichi vari zvipuka zvine masero akawanda muviri - yaitonga uye unicellular siyana kuvapo hadzina kuratidzwa. Kana ari kukura, vanogona kuva akasiyana chaizvo - kufanana webwe kunogona nemaziso, uye kusvika mamita anoverengeka pakureba. Rizivikanwe pagore zvomumvura miti, asi kune vaya vanoita makore 18.

Kana isu kutaura pamusoro pezvakaita uye nemamiriro thalli, panewo kusiyana yokutonga. matope muviri anogona kuva filaments ose ndiro, mabhegi, crusts kana makwenzi diki. Kuna substrate wakasimba kana chirimwa Via bedzi kana rhizoids hurongwa.

Integument hunomiririrwa foni rusvingo, izvo kazhinji inoumbwa zviviri akaturikidzana (matatu akaturikidzana uye ane vamiririri). Rokunze pabutiro rukoko rinoumbwa chaizvoizvo kuti pectin zvinhu uye rinewo sulfated polysaccharides. Yomukati rukoko yaiva unorema cellulose fibers.

Borax algae: muchitokisi mamiriro

An chinokosha hunhu enderana masero ari pamberi plastids. The vamiririri boka iri miti, sero rimwe rine vazhinji duku zvakanaka dzakabudirira chloroplasts. Plastids vane vana membrane. Kazhinji, chokunze Kamudzira pamusoro chloroplast Kamudzira zvinoenda endoplasmic reticulum kana neerekitironi. Kana chlorophyll, pano ngachipiwe nezvimiro A, C1 uye C2.

Uyezve, plastids ose algae rine fucoxanthin, violaxanthin, zeaxanthin uye Beta-carotene, riri chinokosha unhu kuti Plant Taxonomy.

Sero neerekitironi ndiyo chete, kunyange vamwe multi-mhuka. The chikuru chigadzirwa ndiro kupembedza hrizolaminarin kuti iiswe kushandiswa vacuoles kana sezvo cytoplasmic granules.

Kelp uye kubereka

Vamiririri dhipatimendi ichi inogona inoparadzirwa vegetatively, pabonde uye asexually. In dzakawanda marudzi, cloning riri kuitwa vachigoverana thallus. Asi, somuenzaniso, Ficus pamusoro sepasi muviri pane boka masero kushandiswa kuti anogona kurichinja kuva thawed itsva kana zvichidiwa.

Kana asexual muitiro, kazhinji voitakura nenzira zoospores. mhando chete vashoma bereka pachishandiswa wakaiswa monkey kana tetraspor. Panzira, zoospores uye gametes - chete chimiro chokuvapo flagellates kelp.

Kana zvepabonde muitiro, kunogona:

• Isogamous (dzisingaoneki uye mazai ndiwo akaenzana).
• Heterogamic (vechirume gametes vane gametes yakasiyana).
• Oogamnym (varume gametes zvidiki uye pafoni, apo vakadzi oogonia kuramba mira uye yakasiyana guru kukura).

Around pakati 80s remakore rechi20 vave zvawanikwa zvimwe makemikari secreted nomuviri pabonde algae kukura. Ichi chinhu chakafanana mapheromone, kushingaira kudzidza huchavapo kusvikira nhasi.

Kelp uye kuzivikanwa zvikuru vamiririri

Mumwe inozivikanwa zvikuru kwemarudzi anonzi shuga kelp, kana matope. Chirimwa ane guru dissected thawed, wakareba zvinogona kubva 1 kusvika 14 mamita. The thallus vovaka guru yakawanda laminarin. Uyezve, matope anoonekwa tsime rinokosha ayodhini. Mune dzimwe nyika, chirimwa ichi vazvinorimirwa uye kushingaira kushandiswa salads uye dzimwe ndiro. Of Tal uyewo kuti zvinodhaka inoshandiswa pakurapa zvirwere thyroid.

The genus Sargassum zvakare kuzivikanwa, nokuti akafanirwa kune kuramba, refu thalli mvura izvi zvinomera Sea Sargasso panguva vakanga nengozi nokushambira.
