细胞结构模式图


细胞往往外被细胞膜,其内有细胞核(1),核内染色质通常位于核周,核内可见核仁(9)。细胞质内含细胞浆和多种细胞器,如产生ATP的线粒体(6)、内质网(2)、合成新物质的核糖体(3)、高尔基体(7)、溶酶体(5)、吞饮小泡(4)、中间丝(8)。

A basic cell is bounded by a cell membrane. Within the cell is a nucleus containing chromatin, often condensed at the periphery, along with larger clumps called chromocenters, and in some cells a nucleolus into which RNA is concentrated. The cytoplasm contains the cytosol and a variety of organelles, including mitochondria that power the cell via production of ATP, endoplasmic reticulum and ribosomes that synthesize new materials, a Golgi apparatus, and lysosomes.
