Bryophyta:
| Aspect | Details |
| Amphibians of the Plant Kingdom | Bryophytes grow on moist soil but require water for reproduction, earning them the title "amphibians" of the plant kingdom. |
| Structure | The plant body is thalloid, flat, and ribbon-like. Lacks true roots, stems, and leaves; has root-like rhizoids and stem- or leaf-like parts. Multicellular and autotrophic with chlorophyll for photosynthesis. |
| Reproduction | Reproduce through spore formation, which disperses via water to form new plants. |
| Absence of Conducting Tissues | Do not possess specialised tissues (xylem and phloem) for conducting water and food. |
| Examples | Moss (Funaria), Marchantia, Anthoceros, Riccia. |
| Habitat | Found in damp, shaded areas such as forest floors, rocks, and moist soils. |
| Ecological Importance | Prevent soil erosion by forming dense mats over soil. Retain moisture in ecosystems and aid in nutrient cycling. Serve as indicators of environmental quality, monitoring air and water pollution. |
Plants of the bryophyta division
Activity
Observing Mosses:
- Find a green, soft, carpet-like layer on old walls, bricks, or rocks during the rainy season.
- Gently scrape a small sample using a ruler.
- Place the sample under a magnifying lens and observe.
- Notice the tiny, plant-like structures that make up the moss, which thrives in moist environments.
- Discuss its characteristics, such as its small size, green colour, and ability to grow in damp areas.
