Answer: The main function of leaf is photosynthesis. The decomposition of leaf litter constitutes a major pathway of carbon and nutrient cycling in terrestrial ecosystems. Third … Watch Queue Queue Five Important Functions of Leaf. The The veins give support to the leaf. Usually a single layer of tightly-packed cells, the epidermis mediates exchanges between the plant and its environment, limiting water loss, controlling gas exchange, transmitting sunlight for photosynthesis, and discouraging herbivores. carbon dioxide and chlorophyll. The structures within the leaf convert the energy and make it possible for the plant to get food. This process is called photosynthesis. The internal structure of a leaf: Leaves are very important structures. As photosynthesis is the process of synthesising sugars, leaves are also known as sugar factories. Access … The stomata are also responsible for the process of transpiration, the rate at which a plant loses water. Most plants have green leaves and it grows on the branches of a plant. Its main functions are photosynthesis and gas exchange. Leaf Part 2. Let us look at the fine lines at the upper part on the leaf carefully. The U.S. Supreme Court: Who Are the Nine Justices on the Bench Today. Modifications of leaf Parts of leaf Epidermis covers the upper and lower surfaces of the leaf. In addition, the leaves keep a water flow going inside the plant through evaporation and capillarity. Fact Check: Is the COVID-19 Vaccine Safe? Watch Queue Queue. The main function of a leaf is to produce food for the plant by photosynthesis. All Rights Reserved. Functions of leaf. Functional diversity of leaf litter mixtures slows decomposition of labile but not recalcitrant carbon over two years. They are called the side veins. Leaves are made out of several layers that are in between two layers of super tough skin cells called epidermis. 1 a (1) : a lateral (see lateral entry 1 sense 2) outgrowth from a plant stem that is typically a flattened expanded variably shaped greenish organ, constitutes a unit of the foliage, and functions primarily in food manufacture by photosynthesis The leaves and stem together form the shoot.
