Detailed explanation-1: -Bryophytes occupy niches in moist habitats, but, as they lack vascular tissue, they are not very efficient at absorbing water. The rhizoids of a bryophyte may be so fine that they are just one cell thick. Bryophytes also depend on moisture to reproduce.
Detailed explanation-2: -Bryophytes lack rigid support tissues, and therefore grow very close to the ground. Bryophytes-mosses and their relatives-are sometimes described as nonvascular plants because they lack the lignin-hardened vascular tissue found in vascular plants.
Detailed explanation-3: -In all bryophytes, the primary plants are the haploid gametophytes, with the only diploid portion being the attached sporophyte, consisting of a stalk and sporangium. Because these plants lack lignified water-conducting tissues, they cannot become as tall as most vascular plants.
Detailed explanation-4: -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 .
