* They are the primary photosynthetic organs of plants. This means they are responsible for capturing sunlight and using it to produce food (sugars) for the plant.

* They are typically flat and thin. This shape maximizes their surface area for absorbing sunlight and carbon dioxide.

* They have a network of veins. These veins transport water and nutrients throughout the leaf and carry sugars away to other parts of the plant.

* They have a waxy coating (cuticle). This coating helps to prevent water loss from the leaf.

* They have stomata. These tiny pores on the underside of the leaf allow for gas exchange (taking in carbon dioxide and releasing oxygen).

While leaves come in many shapes, sizes, and colors, these core functions are essential to their role in the plant's survival.
