ʻO Venation, ma ka botany, pili i ke ʻano o nā veins i loaʻa ma nā lau o kahi mea kanu. ʻO ka hapa nui o nā lau he hoʻokahi a ʻoi aʻe paha nā aʻa e holo ana ma ko lākou ʻili e lawe i ka wai a me nā meaʻai. ʻElua ʻano maʻamau o ka venation in mea kanu lau: venation like a me reticulate venation.

venation like

ʻO ka parallel venation e pili ana i nā lau lōʻihi a pololei e holo like ana kekahi me kekahi. ʻOi aku ka maʻamau o kēia mau veins i nā mea kanu monocotyledonous, e like me ke kulina a i ʻole ka palaoa.

Nā ʻano o ka venation like

  • Uniaxial: holo like nā veins i kekahi i kekahi a ʻaʻole lālā.
  • Multiaxial: Holo like nā veins i kekahi i kekahi akā lālā i nā manawa he nui.

reticulate venation

ʻO ka reticulate venation e pili ana i nā lau liʻiliʻi, nā lālā lālā e hana i kahi ʻano pūnaewele. ʻOi aku ka maʻamau o kēia mau veins i nā mea kanu dicotyledonous, e like me nā lāʻau hua a i ʻole nā ​​​​legumes.

Nā ʻano o ka reticulate venation

  • Pinnate: ʻo nā aʻa nui mai ke kumu o ka lau a hiki i ka wēlau, a ʻo nā lālā aʻa lua e pili like ana akā pili pū me nā aʻa nui.
  • ʻO Palmate: ʻO kekahi mau aʻa nui mai ke kumu o ka lau, e like me nā manamana lima ma ka lima. ʻO ka lālā veins lua ma ke ʻano like me ka venation pinnate.
  • ʻOkoʻa: ʻoi aku ka nui o nā aʻa kumu mua mai ke kumu o ka lau akā e ʻokoʻa koke, ʻo nā aʻa lua e kū pololei ana iā lākou.
Maʻiʻo kūʻokoʻa - Kaomi maanei  ʻO ka ʻokoʻa ma waena o ka pine a me ka fir

ka hopena

He ʻano koʻikoʻi ka Venation o nā lau mea kanu, a hiki ke lilo i mea hana pono no ka ʻike ʻana i nā ʻano ʻano like ʻole. Ma ka laulā, ʻoi aku ka maʻamau o ka venation parallel i nā mea kanu monocot a ʻoi aku ka maʻamau o ka venation reticulate i nā dicots.
