Leaves are the most important organs of most vascular plants. [8] Green plants are autotrophic, meaning that they do not obtain food from other living things but instead create their own food by photosynthesis. They capture the energy in sunlight and use it to make simple sugars, such as glucose and sucrose, from carbon dioxide and water.
In addition, leaves produced during early growth tend to be larger, thinner, and more irregular than leaves on the adult plant. Specimens of juvenile plants may look so completely different from adult plants of the same species that egg-laying insects do not recognize the plant as food for their young.
In others, the leaves are more compact, forming a rosette (e.g. Echeveria, Aloe). Pebble-plants or living stones (e.g. Lithops, Conophytum) have reduced their leaves to just two, forming a fleshy body, only the top of which may be visible above ground. Ferocactus pilosus (Mexican lime cactus), a stem succulent

As leaves break down, they return nutrients to the soil, which can help plants grow the following year. A layer of fallen maple leaves coat a deck Monday, Nov. 3, 2008 in Coeur d'Alene, Idaho. (AP ...
Nitrogen fixed in this way can become available to other plants, and is important in agriculture; for example, farmers may grow a crop rotation of a legume such as beans, followed by a cereal such as wheat, to provide cash crops with a reduced input of nitrogen fertilizer. [90] Some 1% of plants are parasitic.
As the leaves change for fall, you may find yourself wondering why they do so. The Iowa Department of Natural Resources has insight as to why trees become so vibrant during cooler months, and when ...
Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
