Which Feature Possessed by Most Land Plants Is Missing in Mosses

Which feature possessed by most land plants is missing in mosses, which grow low to the ground in damp, shaded areas?

A) vascular tissue, so they must grow along the ground in damp areas to supply water to the cells
B) cell walls, so they cannot stand upright
C) a protected zygote, so they must grow in damp areas to supply the zygote with moisture
D) chlorophyll b, so they can only use filtered light for photosynthesis
E) starch production, so they only produce small amounts of glucose since any beyond what they use immediately cannot be stored Mosses lack vascular tissue and therefore need to grow in places where they are constantly bathed in water. This limits mosses to damp, shaded areas and prevents the plant from growing upward away from the water used to bathe the cells of the plant.
