Thylakoid and granum

WebbUn granum (plural grana, en latín, ou gra, en galego) é unha morea de discos tilacoidais. Os cloroplastos poden conter de 10 a 100 destas moreas. Os tilacoides estromáticos, intergranais ou lamelas conectan cada granum cos demais. Os tilacoides da grana poden distinguirse dos estromáticos pola súa diferente composición en proteínas.
