Detailed explanation-1: -Mosses and ferns are found in moist and shady places because both require the presence of water for sexual reproduction. As fertilization takes place only in the presence of water, through motile antherozoids that swim to reach the archegonium.

Detailed explanation-2: -Final answer: Ferns and mosses reproduce by spores.

Detailed explanation-3: -Fertilisation occurs when the fern’s egg and sperm combine to form a zygote. Ferns require water to enable the movement of the sperm to reach the egg. A zygote is a combination of genetic material from both the egg and sperm and contains a complete set of DNA to form a new fern plant.

Detailed explanation-4: -Since mosses are non-vascular, they are lacking these tissues, and therefore, they have no transport system. Instead, mosses must absorb their water directly from their environment. This means they must live in damp areas where there is moisture readily available for them to take in.

Detailed explanation-5: -They require a moist environment for reproduction. Their flagellated sperms swim through water to arrive at the egg. Mosses are required to be closer to a water source.
