Gas exchange is more efficient in wet areas.

Without moisture, rhizoids cannot anchor the plants.

Detailed explanation-1: -Bryophytes also need a moist environment to reproduce. Their flagellated sperm must swim through water to reach the egg. So mosses and liverworts are restricted to moist habitats.
Detailed explanation-2: -Like all cryptogams, bryophytes require water for their male gametes or sperm to swim and reach the female gamete during fertilization. Hence, they flourish in moist and shady environments and are known as the amphibians of the plant kingdom.
Detailed explanation-3: -Bryophytes are dependent on water for survival and reproduction. Water is necessary for sexual reproduction in Bryophytes as sperms swim to the eggs to fertilize it.
Detailed explanation-4: -They can be found growing in a range of temperatures (cold arctics and in hot deserts), elevations (sea-level to alpine), and moisture (dry deserts to wet rain forests). Bryophytes can grow where vascularized plants cannot because they do not depend on roots for uptake of nutrients from soil.
Detailed explanation-5: -Bryophytes is the informal group name for mosses, liverworts and hornworts. They are non-vascular plants, which means they have no roots or vascular tissue, but instead absorb water and nutrients from the air through their surface (e.g., their leaves).
