| 释义 | cytoplasm (once / 83235 pages) n The human body is made up of cells, and within every cell is a nucleus — everything else contained within the cell walls is the cytoplasm. This is one of many technical terms for the little building blocks of life within us all. Cytoplasm is material in a cell, such as mitochondria, that aren't the cell's nucleus and control the cell's metabolism. Cytoplasm is full of proteins, which are essential to your body. Cytoplasm is also called protoplasm. To see cytoplasm, you'll need a microscope. To understand cytoplasm, you'll need a good biology teacher and textbook.
