Give examples of thallophytes. Draw a labelled diagram of Spirogyra.
The correct answer and explanation is:
Examples of Thallophytes
Thallophytes are non-vascular plants that lack differentiated plant tissues like stems, leaves, or roots. They typically have a thallus, a simple undifferentiated body. Some common examples of thallophytes include:
- Algae – Simple, aquatic plants that can be unicellular or multicellular. Examples include:
- Chlamydomonas
- Spirogyra
- Ulva (Sea Lettuce)
- Fungi – Non-photosynthetic organisms that obtain nutrients from decaying organic matter. Examples include:
- Rhizopus (common bread mold)
- Penicillium
- Lichens – Symbiotic associations between fungi and algae or cyanobacteria. Examples include:
- Cladonia
- Usnea
These organisms are typically found in aquatic environments or on damp surfaces, and they often play an important role in ecosystems by contributing to the decomposition process or forming symbiotic relationships.
