Sažetak

1. The rliizoids represent the main organs of absorption of nutritive materials by Charophyta. The stem i. e. thallus surface has in this respect but a subordinate function. They can therefore as far as absorption is concerned be compared to the phanerogamous submerse water-plants.
2. The Charophyta grow best in natural siough soil, and in marked decrease steadily weaker in garden-soil, clay- and sandy- soil.
3. The Charophyta are typical shade-plants because they grow best in diffused shadowy light. Their vegetative growth is strongly influenced by direct light.
4. Weak nutrition and strong insolation hasten the fruit formation of the Charophyta.
5. Calcium is indispensable to Chara fragilis:
