Reil [10]

Answer: HOPE IT HELPS MARK AS BRAINLIEST . BYE

Explanation:

Leaf, in botany, any usually flattened green outgrowth from the stem of a vascular plant. As the primary sites of photosynthesis, leaves manufacture food for plants, which in turn ultimately nourish and sustain all land animals. Botanically, leaves are an integral part of the stem system, and they are initiated in the apical bud (growing tip of a stem) along with the tissues of the stem itself. Certain organs that are superficially very different from the usual green leaf are formed in the same manner and are actually modified leaves; among these are the sharp spines of cacti, the needles of pines and other conifers, and the scales of an asparagus stalk or a lily bulb.
