In diatoms the vegetative cells are diploid, and are formed directly by the fusion of gametes. 硅藻类的营养细胞是二倍体，它是由配子融合直接产生的。
These were incubated with shaking for 4 days at 32 C, and the sporulated culture was kept at 45 C overnight to allow autolysis of vegetative cells. 这些培养物在32C下摇动着培养了了4天，孢子培养是保持在45C下一整夜，以便植物细胞自溶。
In some insects with meriostic ovarioles, maternal germ plasm is assembled during oogenesis and contains germline determinants that originated from the perinuclear nuage in the nurse cells. 在某些具有营养细胞型微卵管的昆虫当中，母系生殖浆在卵发育的过程形成，而且生殖浆内所含生殖细胞决定物质系来自于营养细胞的生殖云。
The discovery, Woodruff said, will enable researchers to understand how nurse cells (granulosa cells), the cells that support and surround the maturing egg, communicate with the egg. 伍德乐夫说，这项发现能使研究员们了解营养细胞（颗粒细胞），也就是支撑和环绕逐渐成熟的卵的细胞，如何与卵细胞联系。
