Leaves (together) have entirely different meanings though. The leaves of the oak trees are religioâ¦us symbols of faith and endurance. Ivy leaves symbolize a strong and lasting friendship. This association is derived from its ability to stay attached to a rocky surface in even the most inhospitable conditions.
A leaf is an above-ground plant organ. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere. Plants with leaves all year round are evergreens, and those that shed their leaves are deciduous. Deciduous trees and shrubs generally lose their leaves in autumn.
