Isingeniso

Ku-anatomy yezitshalo, kunezinhlobo eziningana zezicubu. Okubili okubaluleke kakhulu yi-parenchyma kanye ne-collenchyma. Nakuba bobabili bedlala indima ebalulekile esitshalweni, banezici ezihlukahlukene nemisebenzi.

I-Parenchyma

I-Parenchyma iyizicubu zesitshalo ezitholakala kuzo zonke izitho zezitshalo. Yakha ingxenye enkulu yomzimba wesitshalo futhi yakhiwe ngamaseli anezindonga zamaseli ezacile futhi ezihlukene kahle. Umsebenzi wayo oyinhloko ukwenza izinqubo ezahlukene ze-metabolic, njenge-photosynthesis, ukuphefumula kwamaselula kanye nokuhlanganiswa kwezinto ezigciniwe.

Izinhlobo ze-parenchyma

  • I-Chlorophyllous parenchyma: Inesibopho se-photosynthesis. Itholakala ezingxenyeni eziluhlaza zesitshalo, njengamaqabunga, iziqu eziluhlaza kanye nezithelo ezingavuthiwe.
  • I-Reserve parenchyma: Igcina imisoco esitshalweni, njengesitashi noma ama-lipids. Itholakala ezinhlamvini nasezithweni zokuzigcina.
  • I-Hereferous parenchyma: Igcina amanzi ezitshalweni ezihlala emanzini noma ezindaweni ezinomswakama kakhulu.

I-Colenchyma

I-Collenchyma izicubu zezitshalo ezakhiwe amangqamuzana anezindonga eziwugqinsi zamaseli kanye nokuqina okungajwayelekile. Itholakala ezithweni ezikhulayo, njengeziqu ezincane, futhi yakha ungqimba oluhlinzeka ngokusekela isitshalo. Ingase futhi ibe khona emaqabunga nasezimbalini futhi umsebenzi wayo ukunikeza ukuqina nokusekela isitshalo.

Umehluko phakathi kwe-parenchyma ne-collenchyma

  • Amaseli e-Parenchyma anezindonga zamaseli ezacile, ezihlukene kahle, kuyilapho amaseli e-collenchyma anezindonga zamaseli eziwugqinsi, eziqine ngendlela engavamile.
  • I-Parenchyma itholakala kuzo zonke izitho zezitshalo, kanti i-collenchyma itholakala ezithweni ezikhulayo.
  • I-parenchyma yenza izinqubo ze-metabolic, kuyilapho i-collenchyma ihlinzeka ngokusekela kanye nokuqina esitshalweni.

Isiphetho

Nakuba i-parenchyma ne-collenchyma zihlukile ngokuya ngokwakheka nokusebenza kwazo, zombili zibalulekile empilweni yesitshalo. I-parenchyma yenza izinqubo eziyisisekelo ze-metabolic esitshalweni, kuyilapho i-collenchyma isinika ukusekela nokuqina ukuze sikwazi ukwenza. imisebenzi yayo kahle.
