CHARACTERISTICS AND LIFE PROCESSES OF MOSSES
Follow to join WhatsApp Channel. CHARACTERISTICS AND LIFE PROCESSES OF MOSSES. Mosses are small, simple green, seedless, nonvascular plants called Bryophytes. They are simple plants because their roots, stems, and leaves lack a vascular bundle (xylem and phloem) and little or no strengthening tissue. Moss grows in clusters to enable them to conserve water. They…
