Mesophyll Leaf Light Diffusion Cells Large Distance Short

Front What are the adaptations of the leaf
Back A large surface area that absorbs as much light as possible

Minimized overlapping and avoids shadowing of one leaf by another

Thin, diffusion distance is short

Transparent cuticle and epidermis to let light through to photosynthetic mesophyll cells beneath

Long, narrow upper mesophyll cells packed with chloroplast that collect sunlight

Large number stomata for gas exchange so all mesophyll cells short diffusion distance away from one another

Stomata open and close in response to light

Air spaces in lower mesophyll layer to allow rapid diffusion of gas

A network of xylem that brings water to leaf cells, phloem that carries away the sugars produced during photosynthesis.
