Peat moss is the common name of 

Concept-

• Kingdom plants are divided into five groups- Thallophytes, Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms.
• Thallophyta
  • The plant body is not differentiated from roots, stems, and leaves.
  • They are commonly called algae.
• Bryophyta
  • These are small terrestrial plants.
  • They show differentiation in the body design, with stem, leaf-like structures, and root-like structures.
• Pteridophyta
  • The plant body is differentiated into roots, stems, and leaves, apart from having a specialized tissue for conduction.
• Gymnosperms
  • Gymnosperms are plants with naked seeds.
• Angiosperms
  • Angiosperms are seed-bearing plants. Seeds develop inside tissues that get modified to form the fruit of the plant.

Explanation:

• Peat is a fossil fuel that is obtained from the swamp. The formation of peat takes place by the fossilization of Sphagnum
• Thus, Sphagnum is also called ''Peat moss''
• Sphagnum is a member of the class Bryopsida from the group bryophytes

Important Points 

• Sphagnum is known by several other names like:

1. Bog moss - It grows in acidic swamps
2. Carpet or turf moss - it spreads like a carpet on swamps, due to which the swamps cannot be seen easily.
3. Absorbent cotton - It can absorb very high amounts of water
