It has many discoid chloroplasts. But each node consists of a plate Charophyta book small cells. The genera included in Charophyta are very much different from the members of Chlorophyta morphologically and in some other characteristics. It was commonly believed that Charophyta were related to embryophytes land plants. Like plants, they utilize the phragmoplast method of cell division.
The plate has two or more central cells and peripheral cells. Oospore produces filamentous protonema stage. The reserve food material is starch. Charophytes are frequently found in hard water with dissolved calcium or magnesium carbonates.
It should be noted, however, that the Charophyta book classification of organisms is bound to change as further studies of the species would lead to newer system of classification, such as that in The NCBI taxonomy database.
