Chii rhizoids? Basa, mamiriro, Morphology

chirimwa chimwe nechimwe rinoumbwa chikuru zvikamu zvitatu: midzi, hunde uye mashizha. Vari interconnected jira conductive uye nechokwadi zvakajairika kukura. Asi ichi ndicho chinhu evolutionarily zvikuru mberi zvirimwa chete. Utachiona kwakadaro repasi, kufanana mosses, lichens uye algae haagoni kuzvirumbidza yakakwirira azvipire kukura, izvo zvinoreva kuti muviri yavo akagadzirirwa nyore zvikuru. Somuenzaniso, midzi mashandiro yavanobata rhizoids. Chii rhizoids vari algae, mosses nezvimwe chinyakare zvinenge yakatanga? Chii yavo shanduka kukosha?

Chii rhizoids? tsananguro

Rhizoids - a filamentary mugove pakati ezasi zvinomera, inomiririra masero mumwe kana kupfuura uye kuita mudzi chaitika. vari kazhinji Hauoneki, pfupi (pakureba inogona chete munhu millimeters shoma) uye kwete vakakukurira.

Ndoupi musiyano pakati mudzi uye rhizoids?

1. The rhizoids hapana micheka conductive. Osmosis uye ingress mvura mumuviri - ichi ndechimwe chezvinhu zvinokosha mashandiro anoita nemidzi zvinomera. Kana pasina pevhu hurongwa xylem uye phloem, haagoni kunzi midzi vechokwadi.
2. The huchinje kukura nemidzi uye rhizoids. Kana aimbova anogona kusvika makumi ezviuru metres refu uye mutinhimira paupamhi, kuti rhizoids zvidiki, dzimwe nguva kunyange nemaziso inotungamirwa.
3. Mudzi - dzakaunganidzwa vazhinji masero uye munyama. Rhizoids, akavapindurawo, ingangoumbwa nokuda akawanda kana kunyange sero rimwe chete, zvichienderana mabasa.

Zvisinei, mumwe akafanana anogona kuoneka: mudzi, uye rhizoids kuita yakanyatsoti nerevane - kubata muviri chirimwa muvhu. Asi kunyange pano unogona zvakanyatsonanga kuti mudzi zvikuru inoshanda kutsungirira basa ichi pane rhizoids.

Asi rhizoids muri mhando kwomunhu aizotangira kumidzi wechokwadi. idzodzo izvi zviri mubishi yemhindumupindu chamuita kuti mutsva mhando, saka vari zvikuru tichitarisa fauna of, uyewo uwane mubereko remasayendisiti, botanists. Ndizvo rhizoids mu zvipenyu.

mabasa rhizoids

Zvinorehwa zvivako izvi zvipenyu haringorevi kushanda nedanho shanduka. Rhizoids uyewo kuita dzimwe mashandiro chokuita nokutsigira kukura mosses, lichens, algae. Pakati pavo:

1. Bata chikuru chikamu muti muvhu kana mvura pasi, munyaya algae.
2. Gas Exchange uye kusunungura ivhu.
3. Kudzivisa kuonana zvakawandisa mvura, mvura yakawandisa mumate.
4. Absorção de Água.

Izvi ndicho mabasa anogona kuita rhizoids algae uye mosses.

mhando rhizoids

Havasi zvivako zvose pachivande kuti mosses uye algae zvakafanana. Kunyange pakati zvivako nyore zvakadai vakachengeta specialization zvichienderana mabasa uye mamiriro. Chii rhizoids uye zvavari zvakasikwa?

Rhizoids kungava kwakanaka (nyore) uye rurimi. Wokutanga ndiwo kwakajairika pevhu zvivako, izvo vanoshumira kuti kungonzwa chirimwa nemishonga uye kuramba kutadza kufamba kwayo.

Reed rhizoids dzinoratidzwa kuti dhayamita zvavo zvishoma chiduku, masvingo wakawondereiko kudai mazuva ose uye Wavy. Inside zvivako izvi zvinochengetwa growths chakatodzana papillae kana nendimi, saka zita ravo. Mashandiro rhizoids izvi - ndiyo chekubuda nemvura rirambe richibvira chiito Ichibatsirwa kujairika zvakadaro chimiro isina.

Uyewo, ari kudzidza "vakanzwa" rinogona kuwanikwa rhizoids uye zvenguva neshanduro zvivako izvi, izvo nevanopinda zvinhu zvakafanana kumeso uye tsanga analogues. Ndizvo rhizoids maererano siyana kwezvinhu.

Mune dzimwe zvinenge anogona kuwanika rhizoids?

Kare, mosses uye algae vabatwe kuti yakaderera zvinomera, nekuti nechivako yavo yakanga evolutionarily rushoma dzakabudirira kupfuura spore nembeu zvinomera. Vamiririri Vose umambo lichens vari vakacherechedzawo rhizoids, nekuti muviri uyu symbiotic ukama pakati algae uye hunokuvadza. Panzira, dzimwe nhengo notumwe uyewo kuumba rhizoids.

Havasi mosses zvose vane zvivako izvi pachivande. Somuenzaniso, sphagnum, izvo anogara ari wetlands, absorbs mvura yose muviri pamusoro ukuwo, muchiitiko ichi, paumbwe rhizoids kwete zvakakodzera. Ndizvo zvazvakaitawo dzose sfagnumnyh mosses.

Ndoupi musiyano pakati rhizoids uye rizomoidami?

Takadzidza chii rhizoids uye chii basa vaitamba panguva shanduka yose zvipenyu nyika. Zvisinei, pane zvenguva hurongwa pevhu dziri shanduka manera pakati rhizoids uye rhizomes. Zviri pamusoro rizomoidah - rumwe rudzi mudzi mamiriro ari zvakawanda dzakabudirira zvinenge pane chikwindi kana algae.

Rizomoidy zvinomiririra aizotangira rhizomes ose ferns uye Moss. Vari akaumba nokubatanidza rhizoids akawanda zvikuru sokunge ari mumwe chinoramba marongerwo. Zvisinei, havasi vechokwadi Midzi nokuti chete chikonzero sezvo rhizoids ose mosses, algae uye lichens. Zvino zviri pachena kuti rhizoids kwakadaro uye chii musiyano pakati pavo uye rizomoidov.
