1. more chloroplast found on the upper layers of the leaf (eg. palisade mesophyll cells have more chloroplast than spongy mesophyll cells)

2. Leaf is thin to allow efficient diffusion of substances across the leaf eg. water and carbon dioxide for photosynthesis

3. Guard cells contain chlorophyll so that they can photosynthesis and produce sucrose thus causing water to diffuse into the guard cell via diffusion. This makes the guard cell tugid and pulls open the stomata for gaseous exchange eg. CO2 removed

4. vascular bundles in every leaf. Xylem and phloem.

5. cells of the leaf contain chlorophyll in the chloroplast which traps sunlight to carry out photosynthesis

6. the topmost layer is the upper epidermis which is made of transparent cells to allow sunlight to pass through and reach the other cells with chloroplasts

7. Gas chambers exist between the loosely arranged mesophyll cells the increase the surface area of diffusion of carbon dioxide and oxygen during photosynthesis
