Why do plants store energy as carbohydrates and not as fats?
There are quite some reasons for why plants prefer carbohydrates for energy storage rather than fats. I will reach some of them one at a time. Fat hates water: By just applying some common sense, one would get to know that fats are hydrophobic, meaning they literally ''hate'' water i.e. don''t dissolve in water. So, they cannot be transported very ...
