<prompt> Yini oyithola ku-thylakoid? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Kumodeli ye-helical thylakoid, i-grana iqukethe inqwaba yama-thylakoid ayindilinga ayindilinga afana nama-pancake. I-granum ngayinye ingaqukatha noma yikuphi kusuka kuma-thylakoid amabili kuya kwekhulu, yize ama-grana ane-thylakoid eyi-10 × 20 ejwayelekile kakhulu. Ezungeze i-granate kukhona i-helicoid stromal thylakoids, eyaziwa nangokuthi ama-frets noma i-lamellar thylakoids. Ama-helix akhuphuka nge-angle engu-2025, axhumene ne-granal thylakoid ngayinye endaweni yokuhlangana efana nebhuloho. Ama-helicoid angase abe yizingqimba ezinkulu ezixhumanisa ama-grana amaningi, noma abe ngamabhuloho afana neshubhu phakathi kwama-grana. Nakuba izingxenye ezihlukahlukene zesimiso se-thylakoid ziqukethe amaprotheni e-membrane ahlukahlukene, ama-thylakoid membranes aqhubekayo futhi isikhala se-thylakoid esiwahlanganisayo sakha i-labyrinth eyodwa eqhubekayo.
