P. Komáromy, Zs.: Scotiella species (Chlorophyceae) and their theoretical life-cycle

84 Zs. P.-K.OMÁ ROM Y There is another fact referring to partial desorganization or seasonal changes, namely, that all Scotiella species contain yellowish red, orange or uncoloured oil globules (Table 1) in considerable amount. The oil and fat usually are present as food reserve. The biological importance of these substances lies in their high energy content. Like the soods and fruits of flovering plants, the spores and resting cells of algae also contain tnese substances in large quantities, fhe Carotinoid substances dissolve well in lipoids, it is clear that the Carotinoides are accumulating in fat and oil globules.
