Transport in cells GapFill

All cells require certain substances to be moved into or out of the cell. As a result, many adaptations exist for such a need.  InoculationDiffusionTranspirationTranslocationMitosisSpecialisation is the movement of substances  alongdownupwithinbetweennext to a concentration gradient. Importantly, this  does not requirerequireswill usually requiregeneratesmay or may not requirecan sometimes require energy. Examples of the substances that move in this way are  plateletscarbon dioxideamino acidswhite blood cellsalveolioxygen moving into blood in the lungs, or urea moving out of blood in the kidneys.

This process can be sped up by several factors, including increasing the concentration gradient, increasing the  volumefrictionpHlight intensitytemperaturedistance or increasing the surface area of the membrane. Having a  constantuniquelargevariableknownsmall surface-area-to-volume ratio allows this process to occur rapidly, which allows single-celled organisms to exist without complex transport systems. A cube-shaped cell with sides measuring 3 µm has a surface area of  1860543672924 µm² and a volume of  5472918278142 µm³.
