Explanation

Thallophytes are characterised by the simple nature of their structure, i.e. undifferentiated thallus, which has no root, stem and leaf. Plants that do not have well-differentiated body design fall in this group. These plants are mostly aquatic. For example, Spirogyra, Chara, Ulothrix, Cladophora, etc.
