Detailed explanation-1: -The reproduction takes place in water. The male gametes are motile but require water to reach the female gamete. It helps in maturation and dehiscence of sex organs in bryophytes. Water also helps to transfer sperms to archegonium that makes water essential for completion of the life cycle of bryophytes.

Detailed explanation-2: -A moss plant is unable to complete its life cycle in a dry environmnt.

Detailed explanation-3: -Bryophytes need water to reproduce because the sperm must swim to the eggs through water. Once a sperm cell reaches and fertilizes an egg cell in the archegonium, a new generation of the bryophyte life cycle, called the sporophyte, will begin.

Detailed explanation-4: -Water is essential for reproduction in bryophytes for fertilisation. Water is required for the flagellated sperms of bryophytes to reach the egg for fertilisation.

Detailed explanation-5: -Bryophytes are Non-vascular type plants without a vascular system consisting of xylem and phloem . Although non-vascular plants lack these particular tissues, many possess simpler tissues that are specialized for internal transport of water .
