As we already know that the algae are simple thalloid, chlorophyll bearing ,autotropic and aquatics organisms ( both marine and fresh)..These are also divided into three types i.e., Chlorophycae Phyaophycae Rhodophycae... If we will discuss about the storage material in them , it goes as follows:- Chlorophycae:- they have special cells called the pyrenoids which stores protein beside starch. Phyaophycae:- these contain carbohydrates in the form of manitil and laminarin. Rhodophycae:- these contain the food in the form of floriden starch. Hope it helped!!
