Which feature possessed by most land plants is missing in mosses,
which grow low to the ground in damp, shaded areas?
Cell walls, so they cannot stand upright.
Starch production, so they only produce small amounts of glucose
since any beyond what they use immediately cannot be stored.
Vascular tissue, so they must grow along the ground in damp areas to
supply water to the cells.
A protected zygote, so they must grow in damp areas to supply the
zygote with moisture.
