Why Do Scientists Refer To Cells As The Basic Unit Of Life? Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as
Why Is It Better For Cells To Be Small? Cells are so little, so they can maximize their ratio of surface area to volume. Smaller cells have a higher ratio which allow more molecules and ions move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be
