Light micrograph of a plant stem cross section. Haematoxylin and eosin stain.

Plant leaf structure, illustration. Cross-section of a typical plant leaf. In most plants, leaves are the major site of photosynthesis

Leaf epidermis, light micrograph. The leaf epidermis under light microscope view has small pores, called stomata, which open up for photosynthetic gas exchange and transpiration.
