Organization of the cell
All cells, whether prokaryotic or eukaryotic, have a membrane that envelops the cell, regulates what moves in and out (selectively permeable), and maintains the electric potential of the cell. Inside the membrane, the cytoplasm takes up most of the cell's volume. Except red blood cells, which lack a cell nucleus and most organelles to accommodate maximum space for hemoglobin, all cells possess Witryna18 mar 2015 · Subscribe to the Nucleus Biology channel to see new animations on biology and other science topics, plus short quizzes to ace your next exam: …
