While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly this lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is. The importance of having a transport system in multicellular organisms every living organism constantly needs the exchange of substances such as nutrients, waste products, and respiratory gases with the environment in order to survive and grow the exchange of substances between the organism and its environment usually takes place through. Importance of diffusion to living organisms the transport of glucose to cells is by facilitated diffusion and this is needed as all cells need to respire.

Diffusion or passive transport occurs in living organisms without any additional input of energy the process simply occurs if the concentration gradient is such that there is a concentration difference of a particular substance outside and inside a cell membrane.
