The plastids of plants germinated in the dark are termed etioplasts and possess quasi-crystalline structures termed prolammelar bodies that contain the phospholipid materials and chlorophyll precursors that are converted to green chloroplasts in response to light. The micrograph shows a corn (Zea mays) etioplast fixed after brief exposure to light. Te residual prolamellar body is not seen in this section, but, but thylakoid membranes are starting to form and stack. Other images in this group show the prolamellar body.

植物在黑暗中萌发形成的质体被称为原质体，它们具备被称为原叶绿体体的准晶体结构，这些结构含有磷脂物质和叶绿素前体，这些物质在光照下转化为绿色叶绿体。显微照片展示了经过短暂光照固定的玉米（Zea mays）原质体。在本切片中，残留的原叶绿体体不可见，但类囊体膜开始形成并堆积。本组中的其他图像也展示了原叶绿体体。
