what is the function of leaves

Most plants use their leaves to turn water, carbon dioxide, and light energy into the sugars their cells need to function. As cactus leaves turned into cactus spines and lost their ability to photosynthesize, the plants had to find a new way to produce food. Leaves help absorb sunlight and carbon dioxide (CO2), and a leaf is actually an organ of the plant. The outermost layer of the leaf is the epidermis. Petiole. Also Refer: Photosynthesis. A. Leaf pigments absorb light from the sun and store it in the form of chemical energy. It consists of the upper and lower epidermis, which are present on either side of the leaf. Leaf Structure and Function. Transpiration. Its main functions are photosynthesis and gas exchange. We have moved all content for this concept to for better organization. Without sunlight and CO2, plants would be unable to photosynthesize, so there’s a good reason some plants go a bit crazy on leaf production! A leaf is an above-ground plant organ and it is green. Find out more about the role of leaves in this Bitesize Primary KS2 Science guide. Describes the structure and function of leaves. The function of leaves is to help the plant produce food by converting the energy in sunlight into chemical energy that the plant can eat. Manufacture of food. Also, leaves have large amounts of stomata that expel the water by the process called transpiration. 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. The function of leaves: The main feature of leaves is providing food or fruits leaves directly attach with vascular and veins of the plant where they can transfer minerals waters from all parts of the tree and also extract minerals from roots to this way leaves also have its own veins; The process is called photosyn­thesis by which leaf manufactures food material in the presence of sunlight and green pigment- chlorophyll present in the leaf. Parts of a Leaf Diagram. This sending of water into the air also reduces the temperature. Leaves help plants survive through photosynthesis. Thus the light reflected in space from plants is low. They convert carbon dioxide, water, and UV light into glucose through the process of photosynthesis. The epidermis aids in the regulation of gas exchange. 1. A typical leaf shows three main parts: 1) petiole, 2) leaf base, and 3) leaf blade or lamina, each performing specific functions. Transpiration is the removal of excess water from the plants into the atmosphere. The Functions of Needle Leaves. The leaves perform the following functions: Photosynthesis. Since cacti have thick fleshy stems, these took over the job of photosynthesis. The functions of modified leaves are not dealt as they carryon spe­cialised functions as discussed earlier. Please update your bookmarks accordingly. It is the primary function of green leaves. Evergreen conifers are some of the oldest trees in the world, and for good reason. It is the stalk that connects a leaf to the stem of the plant, it is made of complex conducting tissues called vascular tissues. Photosynthesis is the primary function of leaves. The structures within the leaf convert the energy and make it possible for the plant to get food. What do plant leaves do? Botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis). Most leaves have stomata, which open and close.They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere. Veins form the midrib of the leaf, which gives a leaf structure.
