Stoma

Microscopic top-view surface view of a single stomatal complex in the leaf epidermis. A narrow dark slit-like to slightly oval central pore with tapered ends is bordered by two symmetrical curved kidney-shaped green guard cells. The guard cells have smooth walls with thicker inner walls facing the pore and thinner outer walls, darker outlines, lighter green interiors, and several small chloroplast-like dots inside. The stoma sits within a flat, pale epidermal surface with surrounding polygonal epidermal cells and minimal texture, keeping focus on the paired guard cells and central opening.
