分批培养物的对数期和稳定期对杜氏杜氏藻的光学和电子显微镜观察结果是相关的。除了缺乏细胞壁外，其精细结构具有典型的杀虫剂特征。从对数期到稳定期的转变以细胞质空泡的内容和大小的变化、细胞质脂质的积累、质体基质中淀粉的积累以及自噬体样体的形成为标志。由于细胞质脂质和淀粉膨胀的叶绿体，静止期鞭毛虫中的细胞器紧密堆积在一起。对数生长期的生物体具有丰富的核糖体填充的底质来支持细胞器。在酸性磷酸酶活性的细胞化学证明中，高尔基体池以及光滑和包被的高尔基体囊泡含有Gomori反应产物。讨论了高尔基体在这种鞭毛中的可能作用。
Light and electron microscope observations onDunaliella primolectaButcher from logarithmic and stationary phases of batch cultures are correlated. Except for the lack of a cell wall the fine structure has typical volvocid features. The transition from logarithmic to stationary phase is marked by changes in content and size of cytoplasmic vacuoles, accumulation of cytoplasmic lipid, accumulation of starch in the plastid matrix, and by the formation of autophagosome‐like bodies. The organelles in stationary‐phase flagellates are closely packed together because of the cytoplasmic lipid and starch‐distended chloroplast. Organisms from logarithmic phase have an abundant ribosome‐packed groundplasm supporting the organelles. In the cytochemical demonstration of acid phosphatase activity, Golgi cisternae and smooth and coated Golgi vesicles contain Gomori reaction product. The possible roles of the Golgi apparatus in this flagellate are discussed.
