Mosses (Bryophytes) occur in moist places because
1 They cannot grow on land
2 They donot have pigment system
3 Fusion of gametes occur in water
4 They lack root and vascular tissue
Explanation:
Mosses can live in soil but are dependent on water for sexual reproduction. Hence, they usually occur in damp, humid and shaded localities.

Bryophytes are called ‘amphibians of the plant kingdom’ because
1 They have evolved from frogs
2 They grow only in water
3 These plants grow in soil, but are dependent on water for sexual reproduction
4 both 2 and 3

Spore in bryophytes are formed
1 On the gametophyte
2 In the capsule of sporophyte
3 In the seta of sporophyte
4 In the foot of sporophyte
Explanation:
Some cells of the sporophyte undergo reduction division (meiosis) to produce haploid spores. These spores present in the capsule of sporophyte germinate to produce gametophyte.
