Answer:
Photosynthesis
Explanation:
The leaf (from Latin fŏlĭum, fŏlĭi) is the vegetative and generally flattened organ of vascular plants, specialized mainly to perform photosynthesis. The morphology and anatomy of stems and leaves are closely related and, together, both organs constitute the stem of the plant.
Typical leaves - also called nomophiles - are not the only ones that develop during the life cycle of a plant. From the germination, different types of leaves follow each other - coiled, primordial leaves, prophilic, bracts and antophiles in flowers - with very different forms and functions.
A nomophile usually consists of a flattened sheet, a short stem - the petiole - that joins the sheet to the stem and, at its base, a pair of appendages - the stipules. The presence or absence of these elements and the extreme diversity of forms of each of them has generated a rich vocabulary to categorize the multiplicity of types of leaves presented by vascular plants, whose description is called foliar morphology.
