Waa maxay midabka waa plastids ee dhirta

jirka ah ee dhirta ku salaysan tahay hab ee photosynthesis - Isbadal tamarta qoraxda galay tamarta kiimikada. Hay'adda ugu weyn ee photosynthesis waa xaashi. dusha waxaa lagu daboolayaa sheet khafiif ah oo maqaarka - epidermis, oo ku yaalla under hlorenhima - unug ka mid ah, unugyada kaas oo geedi socodka waxaa lagu fuliyaa photosynthesis. In dhirta qaar ka mid ah oo u dhexeeya epidermis iyo hlorenhimoy waa lakabka kale oo dheeraad ah ee unugyada, kaas oo loo yaqaan "hypodermis". unugyada hypodermal ahaayeen hufan, oo ay shaqo weyn waa in ay u kala firdhin qorraxda.

unugyada hlorenhimy ku jira ee organelles ugu weyn, photosynthesis dhacdaa -plastidy. Oo ku saabsan waxa ay tahay iyo waxa color waa plastids ah, waxaan ka Dabcan biology dugsi bartaan.

Waa maxay plastids ah

Plastids - waa organelles intracellular, hareereeyeen by xuub double. Inside kasta oo caag ah oo dareere gaar ah ka buuxsantay - furta. Shaxda waxaa ku jira ensaymes ee lagama maarmaanka u ah ereygu wuxuu ahaa ee glucose - wax soo saarka ugu dambeeya ee photosynthesis. Isticmaalka noocyo kala duwan oo falgalka 6 taagoo of carbon dioxide iyo biyo 6 waxaa beddelay 2 molecules glucose. Mid ka mid ah "jilayaasha" muhiimsan waa Britain hlorovilla - Midabka cagaarka ah, taas oo ku siinayaa midabka si ay caleemaha dhirta.

noocyada plastids

Haddii uu ilmuhu wax kaa barya waxa color waa plastids ah, ha ku degdegin inaad ka jawaabto, in ay hubaal cagaaran. Waxyaabaha sidaas ma aha mid fudud! plastids Color lifaaqan Midabka in ay ka kooban yihiin. Iyadoo taas ku xiran, waxaa jira dhawr nooc: proplastids, leucoplasts, chloroplasts, chromoplasts. Waxay ku xiran tahay nooca iyo midabka ah ee plastids yihiin.

Proplastids - a organelles midab ah taasi oo markii dambe la sameeyey oo dhan noocyada kale ee plastids. Leucoplasts sidoo kale midabada aadan haysan. Chloroplasts waa cagaar, oo ay go'aan ka midabka ah ee caleemaha iyo asliga ah.

Chromoplasts - taasi waa nooca ugu badan ee qalaad plastid. chromoplasts The Matrix sederzhatsya carotenoids, iyo haddii ay taasi ku qeexo waxa laga yaabaa in midab plastid ah - orange, jaalle ah, casaan, oo cas, Burgundy ah ama maariin ah. Chromoplasts siin midabka caan ku ubax iyo miraha.

shaqada plastids

On waxa midabo kala noqon kartaa plastids, waxay ku xiran tahay shaqadooda. More hufan, Midabka waxaa ka mid ahaa in ay Halabuurka. Ugu weyn ee shaqada plastids waa photosynthesis, laakiin dhammaantiin ma aha ee plastids waa awood photosynthesis, iyo chloroform iyo chromoplasts kaliya.

Leucoplasts - a plastids "jir koray", kuwaasi oo loo isticmaalo si loogu kaydsado walxaha, inta badan noqde iyo proplastids dawadda oo dhan noocyada kale ee plastids.

Sayidka, hawlaha ay ku xiran tahay waxa midabo kala noqon kartaa plastids. chloroplasts Green synthesize walxaha cusub, iyo chromoplasts midab iyo dhalaalaya soo jiidan pollinators in ubax. leucoplasts Biyuhu hayn kaydka ee nafaqooyinka.
