Detailed explanation-1: -Bryophytes have life cycles that depend on water for reproduction. Bryophytes draw up water by osmosis only a few centimeters above the ground. During one stage of their life cycle, bryophytes produce sperm that swim through water to reach eggs of other individuals.
Detailed explanation-2: -They grow directly out of the fertilized egg in the archegonia, and remain dependent on the parent gametophyte for their nutrition. Hence the correct option is D.
Detailed explanation-3: -Instead they have rhizoids, which are small hairlike structures. Their main function is anchoring the plant to rock, bark or soil. So without roots, some moss suck nutrients up through the rhizoids and others draw in moisture and minerals from rain and the water around them through their highly absorbent surfaces.
Detailed explanation-4: -Out of the statement given for the bryophytes, the only correct statement given for the bryophytes, the only correct statement is that they can live in soil, but are dependent on water for sexual reproduction. Thus, are called amphibians of plant kingdom.
