3D Leaf Cross-section: The leaves have a complex mechanism, and their various parts carry out the whole process of photosynthesis. They stoma cells and chloroplast, which get active when photon cells hit them, and then the process of photosynthesis occurs. In the example of a 3D leaf cross-section, there are different parts of the plant identified with labels. It helps a student to understand the mechanisms that take place in a plant. The microscopic diagram makes it easier to learn the function of the leaves.
