The primary function of a leaf
is the respiratory system of a plant . . .
to collect sunlight, water and nutrients,
absorbing carbon dioxide through
photosynthesis, expiring oxygen
to build tissue throughout the rest of the plant.
It is the vascular system that transports
these fluids and nutrients, i.e. the veins in each leaf.
Beyond the science of this system
is the beauty of a leaf's veins.
Visible to the naked eye,
each leaf reveals its vascular design.
Next time you're at the market,
pick up a leaf of swiss chard
and admire its beauty.
Behold a work of art!
