- large surface area so absorbs as much sunlight as possible
-arrangement of leaves on a plant minimises overlapping - so avoids the shadowing of one leaf by another
-transparent cuticle and epidermis -let light through to the photosynthetic mesophyll beneath
-numerous stomata -short diffusion pathway to mesophyll cells
