       植物细胞中存在的一种细胞器.由一层单位膜所包围的球状颗粒.内部有细微的颗粒结构.其化学组成主要是脂类和蛋白质.圆球体含有水解酶和脂肪酶，与溶酶体的性质相似，但它有积聚脂肪的功能.圆球体来源于内质网.内质网的一端因积聚脂类物质和蛋白质而膨大，然后从内质网上脱离下来而成为前圆球体，前圆球体进一步增大体积成为圆球体.Exist in a plant cell organelles. Surrounded by a layer of unit membrane of the spherical particles. Internal structure of fine particles. Its chemical composition is mainly lipid and protein. Coccoid contains hydrolytic enzymes and lipase, and the dissolved enzyme body similar in nature, but it is the accumulation of fat function. coccoid from the endoplasmic reticulum. endoplasmic reticulum, one end of the accumulation of lipids and proteins due to the expansion of the ER and then down the line to become before the ball away from body, the former spherical body and further increase the volume of a sphere.
