<span>Early life was too simple to fully fix the sun or use higher functions to provide it's own energy. They were probably more like archaea that are seen around vents in extreme regions, such as the floor of the ocean or in high temperature pools in Yellowstone. These items "eat" the sulfur and other energy to create their needs. This would develop by necessity into mitochondria and chloroplast like bacteria as they ventured out from the vents to other areas and competed for heat and energy</span>
<span>Glucose which can also be fats from excess carbohydrates.
Carbohydrates actually get stored in the form of long polymers of glucose molecules or as glycogen starch. They provide energy to the animals for performing their daily duties. Carbohydrates are generally considered the fuel for all organisms, and without this most animals would become sloth and would be unable to perform the regular jobs. Carbohydrates are actually very easy to metabolise and hence generate quick energy.<span>

for this occurrence to happen, a cell doesn't has to interact with other cell, which also commonly described as intracellular communication
