Zoospore - mufananidzo upenyu kutenderera uye kubereka nzira

Pashure kuverenga nyaya ino, uchakwanisa kuita mashoko anokosha siyana nharo - zoospores. Tichatevera kukuudza sei vari atumidzwa, tinyatsoziva zvimwe, mashandiro, uye mhaka.

Chii zoospore

Zoospore - mufananidzo yakawanda algae uye hunokuvadza nechepazasi diki chikamu upenyu kutenderera. Zvikasadaro zoospores akadana crawlers mune zvimwe zviitiko, uye vamwe - zoogonidiyami. Izvi mhando nharo anokwanisa kutama, nokuti chii chaizvoizvo anowana zita rayo.

Zoospore - anoverengeka protists, mumwe wavo upenyu siyana kuti unogona kukurira zvimwe kure mvura mvura. Muitiro kufamba ndiko nokuda kurova mumwe kana kupfuura flagella.

Panguva iyi pokumuka pakubhadhara yakawanda algae vane rusarura (intracellular organelle) chromatophore (masero kuti vatakure pigments uye vanokwanisa kutevedzera chiedza) uye contractile vacuoles (organelles basa achibvisa zvakawandisa mvura kubva cytoplasm). Yellow-nyoro algal marudzi ari pavaipfuura zoospores vanokwanisa akatakura vakawanda nuclei.

Kubereka uye chirongwa chidzoke

Kubereka zoospores, sezvataurwa pamusoro apa, Ndiwo vamiririri dzakawanda algae uye ezasi notumwe. Mitotic uye meiotic kupesana zoosporangia (sero chinokosha) - ichi chinoreva panowanikwa zoospores. A zoospore - yokugara rwakazara.

Pashure imwe nguva rwunotanga chisanyanya muchitokisi flagellum uye, pashure iyi kwapera, anotanga kuti vaunze sero rusvingo pamusoro compressed mhando, uye ipapo kutanga muitiro kuparadzanise uye pakupedzisira kuumbwa howa mycelium kana thawed algae.

Ndaverenga nyaya zvinhu anogona muchidimbu kuti zoospore - zvose:

• chikamu upenyu kutenderera wevamiriri akawanda umambo notumwe uye algae;
• nzira kugadzirisa pamusoro ndima mvura;
• ramangwana akura muviri chirimwa kana howa munyika.
