DENDROLOGY

Detailed explanation-1: -Mosses are Bryophytes which are nonvascular land plants . They are found in damp and shady places and lack true stem, leaves, roots, and vascular systems.

Detailed explanation-2: -Chlorophytes have no vascular tissue.

Detailed explanation-3: -Mosses have some water-conducting cells, but they do not have the empty, lignin-reinforced cells that allow vascular plants to transport water with strong pressure gradients. Thus, mosses have very limited water transport ability and can’t grow very tall.

Detailed explanation-4: -Most bryophytes are small. They not only lack vascular tissues; they also lack true leaves, seeds, and flowers. Instead of roots, they have hair-like rhizoids to anchor them to the ground and to absorb water and minerals (see Figure below).
