Thallophyta
Thallophyta is a group of plants that includes algae, fungi, and lichens. In thallophytes, fertile cells are not enclosed by sterile cells. This is because thallophytes lack specialized structures like flowers or cones that enclose reproductive cells. Instead, the reproductive cells are often exposed to the external environment.
Explanation:
Thallophytes:
- Thallophytes are a group of plants that do not have well-differentiated plant bodies.
- They lack true roots, stems, and leaves.
- Examples of thallophytes include algae, fungi, and lichens.
- In thallophytes, the reproductive structures are not enclosed by sterile cells, unlike in other plant groups like spermatophytes, pteridophytes, and bryophytes.
Reproductive Structures in Thallophytes:
- In algae, reproductive cells are often exposed to the external environment, where they can be dispersed by water or air.
- Fungi reproduce through spores that are produced in specialized structures like mushrooms.
- Lichens reproduce through the dispersal of fungal spores and algal cells.
Conclusion:
Thallophytes, which include algae, fungi, and lichens, do not have reproductive structures that are enclosed by sterile cells. This sets them apart from other plant groups like spermatophytes, pteridophytes, and bryophytes, which have specialized reproductive structures that enclose fertile cells.
