The rhizoid cell is de- pendent on the other cells of the filament, and sugars produced by photosynthesis in the green cells are transferred to this colorless cell by diffusion through the intervening cell membranes. Among the most highly differentiated of fresh-water algae is Nitella (Fig. 13-2). This relatively large green alga may measure al- most a foot in length. Nitella exhibits a branching green "stem," which is attached to colorless rhizoids at the lower end, and which is su
