The leaf because it is the major structure for photosynthesis in a plant.he leaf would have the most chloroplasts because it is the major  structure for photosynthesis in a plant.
This process occurs in almost all plant species and is carried out in specialized organelles known as chloroplasts.

On the average, the chloroplast density on the surface of a leaf is about one-half million per square millimeter.
