2. utu Gas me te whakakaewa i te oneone.
3. Tupato ano whakapā ki te wai i te taikaha, rūrūtia wai rawa nui.
4. mimititanga wai.

Ko te mahi tino noa e taea te mahi i rhizoids pükohu me talingelingá tenei.

momo rhizoids

I mua, kua tukinotia Kiwa me pükohu ki te tipu o raro, no te mea ko evolutionarily iti whakawhanakehia atu i roto i nga otaota spore me purapura ratou hanganga. Kei te kitea hoki ngā māngai katoa o te kingitanga o hawahawa rhizoids, no te mea ko tenei rauropi he hononga taupuhipuhi i waenganui i pükohu me harore. E te ara, i whai ahua ai hoki te tahi mau melo o te harore rhizoids.

Ehara i talingelingá katoa i enei hanganga raro. Hei tauira, sphagnum, e nohoia te repo, absorbs wai puta noa i te mata tinana, aua, i roto i tenei take, te hanganga o rhizoids kore e tika. he rite i roto i te talingelingá sfagnumnyh katoa te āhuatanga.
