A close-up of a microscopic view of a plant stem. The stem is made up of multiple layers of cells with the top layer being a light brown color and the bottom layer a darker brown color. The cells are arranged in a radial pattern with some overlapping each other. On the right side of the image there is a small amount of small white particles which appear to be particles that are scattered across the surface of the stem. On the left side there are two vertical bars one labeled "High pH" and the other labeled "Low pH". The high pH bar is on the top left corner while the low pH bar on the bottom right corner is in the center. The background is a pale blue color which contrasts with the light brown of the cells. The image appears to be a 3D rendering giving it a realistic and detailed appearance.
