Detailed explanation-1: -Cells are so little, so they can maximize their ratio of surface area to volume. Smaller cells have a higher ratio which allows more molecules and ions to move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
Detailed explanation-2: -If a cell was to get very large, the small surface area would not allow enough nutrients to enter the cell quickly enough for the cell’s needs.
Detailed explanation-3: -With smaller cells, more surface area is available for oxygen and nutrients to diffuse in and carbon dioxide to diffuse out of the cell. Thus many small cells can take up oxygen and nutrients and release carbon dioxide much more quickly than one large cell.
Detailed explanation-4: -Small cells have larger surface area to volume ratio. This means that with more surface area, things such as nutrients, oxygen, and carbon dioxide can readily pass in and out of the cells through its pores. If the volume to surface area ratio was smaller, the cell would be much less efficient in its tasks.
