During chloroplast division in Olisthodiscus luteus Carter, the envelope of chloroplast ER may infold either in synchrony with the chloroplast envelope or lag markedly behind the chloroplast envelope giving two different patterns of division. In the first type of division the chloroplast ER infolds in parallel with the chloroplast envelope as the plastid pinches in two. In the second more common type of division, the chloroplast envelope infolds, meets and fuses before the chloroplast ER begins to infold thus producing two plastids in a single sac of chloroplast ER. Separation of these plastids is accomplished by the subsequent infolding of the chloroplast ER.
