Thallophyta:
| Aspect | Details |
|---|---|
| Habitat | Mostly aquatic, living in both freshwater and saline environments. |
| Structure | Plants lack specific organs like roots, stems, leaves, and flowers. Bodies are soft, simple, and fibre-like. |
| Chlorophyll and Autotrophy | Algae are autotrophic due to the presence of chlorophyll, enabling photosynthesis. They may be unicellular or multicellular, microscopic or large. |
| Examples of Algae |
Freshwater: Spirogyra, Ulothrix. Saline water: Ulva, Sargassum. |
| Fungi in Thallophyta | Includes organisms like yeasts and moulds that lack chlorophyll. Unlike algae, fungi are heterotrophic, obtaining nutrients through decomposition or symbiosis. |
| Diversity | Algae show significant diversity in size, form, and habitat. For example, Spirogyra (filamentous) and Sargassum (large and leafy). |
| Ecological Importance | Algae produce oxygen through photosynthesis, serve as food sources, and provide bioactive compounds. Fungi help in nutrient cycling and decomposition. |
