Plastid is a two-membrane-bound organelle that is involved in the synthesis and preservation of nutrients. typically found in the photosynthesis cells of plants. Plastids were first discovered and identified in the work of Ernst Haeckel, but A. F. W. Schimper was the first to offer an accurate definition.
It is common to discuss fat as if it was a villainous substance that is bent to destroy our diets. However, they are beautiful tiny molecules composed of three hydrocarbon tails that are attached to a small coathanger-like molecule known as Glycerol. Similar to the other big organic molecules they perform crucial functions in the biology of both humans and other living things. (Also numerous recent diet studies suggest that sugar can cause many more health issues that fat!)
