Artist's Description

Typically leaves are broad, flat and thin, thereby maximising the surface area directly exposed to light and promoting photosynthetic function. They are arranged on the plant so as to expose their surfaces to light as efficiently as possible without shading each other, but there are many exceptions and complications; for instance plants adapted to windy conditions may have pendent leaves, such as in many willows and Eucalyptus.
The internal organisation of most kinds of leaves has evolved to maximise exposure of the photosynthetic organelles, the chloroplasts, to light and to increase the absorption of carbon dioxide. Gas exchange is controlled by stomata, which open or close to regulate the exchange of carbon dioxide, oxygen, and water vapour with the atmosphere. In a given square centimeter of a plant leaf there may be from 1,000 to 100,000 stomata.
Some leaf forms are adapted to modulate the amount of light they absorb to avoid or mitigate excessive heat, ultraviolet damage, or desiccation, or to sacrifice light-absorption efficiency in favour of protection from herbivory. For xerophytes the major constraint is not light flux or intensity, but drought. Some window plants such as Fenestraria species and some Haworthia species such as Haworthia tesselata and Haworthia truncata are examples of xerophytes. and Bulbine mesembryanthemoides. Read more
