Abstract

SUMMARY: The ultrastructural development of A was studied in preparations grown in darkness and sampled during succeeding intervals in the light. The major effect on ultrastructure during light-induced development is a re-organization of the thylakoid lamellae. The lamellar pattern in dark-grown aseriate organisms differs from that displayed by those grown in the light. Transfer of dark-grown algae to light results in breakdown of the original lamellar complement and formation of parietal whorls of lamellae. Within the dark-grown aseriate packets, some of the component cells which are indistinguishable in light microscopy can be identified ultrastructurally as immature heterocysts. Maturation of the heterocysts occurs after transfer to the light.
