Assertion : Sphagnum is slowly carbonised, compressed and fossilised over thousands of years to produce a dark spongy mass called peat. Reason : Peat helps to keep soil porous and it also improves water holding capacity of soil.
1 Both Assertion and Reason are true and Reason is correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.
Explanation:
Sphagnum peat mass is slowly carbonised, compressed and fossilised over thousands of years to produce a dark spongy mass called peat. It has a remarkable ability to manage water efficiently and holds to nutrients that would otherwise leach out of the soil.

Plants referred to as amphibians of plant kingdom are
1 Pteridophytes
2 Gymnosperms
3 Angiosperms
4 Bryophytes
Explanation:
Bryophytes are also called amphibians of the plant kingdom because these plants can live in soil but are dependent on water for sexual reproduction.
