Chloroplast development and ultrastructure of the freshwater red alga Batrachospermum moniliforme are described. Chloroplasts develop from proplastids which have a double-membraned chloroplast envelope and a parallel double-membraned outer photo-synthetic lamella. Of these 2 double-membraned structures of the proplastid, only the outermost pho-tosynthetic lamella functions in production of further lamellae. The mature chloroplast consists of 2 or more concentric lamellae and a variable number of nonconcentric lamellae. These lamellae are not dense, uninterrupted sheets as described for other red algae, but are largely constructed of tubules, lying side by side, that form interrupted lamellar sheets. The possible physiological significance of lamellar interruptions in providing path-ways for movement of materials in the chloroplast stroma is discussed.
描述了淡水红藻串珠蛙卵藻的叶绿体发育和超微结构。叶绿体由前质体发育而来，前质体具有双膜叶绿体被膜和与之平行的双膜外光合片层。在前质体的这两种双膜结构中，只有最外层的光合片层在进一步片层的产生中起作用。成熟的叶绿体由2个或更多的同心片层和数量可变的非同心片层组成。这些片层不像其他红藻那样是致密、连续的薄片，而是主要由并排排列的小管构成，这些小管形成间断的片层薄片。讨论了片层间断在为叶绿体基质中物质移动提供途径方面可能的生理意义。
