caption: The image shows a white paper with a leaf and a piece of paper on it, along with a scale, color palette, and text. The leaf appears to be a pistil, with its distinct shape and texture. The scale is likely used to measure the size of the pistil and the color palette could be used to identify the different parts of the plant. The text on the paper likely provides additional information about the plant, such as its name, species, and other information.
