  1. Photosynthesis

    Photosynthesis is a process used by plants and other autotrophic organisms to convert light energy, normally from the sun, into chemical energy that can be used to fuel the organisms' activities. Carbohydrates, such as sugars, are synthesized from carbon dioxide and water during the process. Oxygen is also released, mostly as a waste product. Most plants, most algae, and cyanobacteria perform the process of photosynthesis, and are called photoautotrophs. Photosynthesis maintains atmospheric oxygen levels and supplies most of the energy necessary for all life on Earth, except for chemotrophs, which gain energy through oxidative chemical reactions. Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centres that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances such as water. This produces oxygen gas and hydrogen ions, which are transferred to a compound called nicotinamide adenine dinucleotide phosphate, reducing it to NADPH. More light energy is transferred to chemical energy in the generation of adenosine triphosphate, the "energy currency" of cells.

U.S. National Library of Medicine

  1. Photosynthesis

    The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide using energy obtained from light rather than from the oxidation of chemical compounds. Photosynthesis comprises two separate processes: the light reactions and the dark reactions. In higher plants; GREEN ALGAE; and CYANOBACTERIA; NADPH and ATP formed by the light reactions drive the dark reactions which result in the fixation of carbon dioxide.

Sample Sentences & Example Usage

  1. Wim Peters:

    Red light is very important for photosynthesis and growth, but you need blue light to give the tomato a good shape.

  2. Chris Bowler:

    Plankton are much more than just food for the whales, although tiny, these organisms are a vital part of the Earth's life support system, providing half of the oxygen generated each year on Earth by photosynthesis and lying at the base of marine food chains on which all other ocean life depends.

  3. Gavin Munro:

    We grow the chairs upside down and we start with one branch that spreads out into the chair-back. So, you've gone from one to two, and then the seat, and then you've got the four legs; and it's much more of a tree shape, actually it works in a similar way to 3D printing... we're using photosynthesis for the printing. So as it grows, you've got a piece growing up.
