Fig. 36.—A palisade-cell. The chloroplasts are somewhat biscuit-shaped bodies, being roughly circular in face-view and elliptical when seen from the side. They are embedded in the thin and transparent layer of cytoi)lasm, their broad faces parallel to the cell wall. The chloroplasts which here appear circular are therefore lying against the front wall, nearest the observer. Those which appear elliptical are lying next the side walls. the food manufactured there and convey it to the bast of the stem, along which it is transported to other parts of the plant. The petiole, usually circular in cross section, has within it a cylinder or half-cylinder of fibro-vascular bundles which are con-.
