<prompt> Kuthatha isikhathi esingakanani ukuba i-prolameller iqale ukwakha ama-chylacoid ngemva kokuchayeka ku-chlorophyll? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Uma amahlumela e-angiosperm engachayeki ekukhanyeni okudingekayo ukuze kwakheke ama-chloroplast, ama-proplastids angathuthuka abe isigaba se-etioplast ngaphambi kokuba abe ama-chloroplast. I-etioplast iyi-plastide engenayo i-chlorophyll, futhi ine-membrane yangaphakathi enama-invaginations akha i-lattice yamashubhu ku-stroma yawo, ebizwa ngokuthi umzimba we-prolamellar. Nakuba ama-etioplast engenayo i-chlorophyll, anesandulela se-chlorophyll esiphuzi. Emizuzwini embalwa nje ngemva kokuchayeka ekukhanyeni, umzimba we - prolamellar uqala ukuhleleka kabusha ube yizinqwaba zama - thylakoid, bese kuqala ukukhiqizwa kwe - chlorophyll. Le nqubo, lapho i-etioplast iba i-chloroplast, ithatha amahora amaningana. Ama-gymnosperm awadingi ukukhanya ukuze akhe ama-chloroplast.
