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.
Photosynthesis<span> is a process used by plants and other organisms to convert </span>light<span> energy into </span>chemical energy<span> that can later be </span>released<span> to fuel the organisms' activities (</span>energy transformation<span>). This chemical energy is stored in </span>carbohydrate molecules<span>, such as </span>sugars<span>, which are synthesized from </span>carbon dioxide<span> and </span>water<span> – hence the name </span>photosynthesis<span>, from the </span>Greek φῶς<span>, </span>phōs<span>, "light", and </span>σύνθεσις<span>, </span>synthesis, "putting together".<span>In most cases, </span>oxygen<span> is also released as a waste product. Most </span>plants<span>, most </span>algae<span>, and </span>cyanobacteria<span> perform photosynthesis; such organisms are called </span>photoautotrophs<span>. Photosynthesis is largely responsible for producing and maintaining the </span>oxygen content<span> of the Earth's atmosphere, and supplies all of the organic compounds and most of the energy necessary for </span>life on Earth<span>.</span>
