2. Photosynthesis - Wikipedia

   en.wikipedia.org/wiki/Photosynthesis

   Photosynthesis usually refers to oxygenic photosynthesis, a process that produces oxygen. Photosynthetic organisms store the chemical energy so produced within intracellular organic compounds (compounds containing carbon) like sugars, glycogen , cellulose and starches .

3. Fire ecology - Wikipedia

   en.wikipedia.org/wiki/Fire_ecology

   Fire has played a major role in shaping the world's vegetation. The biological process of photosynthesis began to concentrate the atmospheric oxygen needed for combustion during the Devonian approximately 350 million years ago. Then, approximately 125 million years ago, fire began to influence the habitat of land plants.

4. Plant cell - Wikipedia

   en.wikipedia.org/wiki/Plant_cell

   Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...

5. Light-dependent reactions - Wikipedia

   en.wikipedia.org/wiki/Light-dependent_reactions

   In oxygenic photosynthesis, the first electron donor is water, creating oxygen (O 2) as a by-product. In anoxygenic photosynthesis, various electron donors are used. Cytochrome b 6 f and ATP synthase work together to produce ATP (photophosphorylation) in two distinct ways.

6. Calvin cycle - Wikipedia

   en.wikipedia.org/wiki/Calvin_cycle

   The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction (PCR) cycle [1] of photosynthesis is a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose. The Calvin cycle is present in all photosynthetic eukaryotes and also many ...

9. Biology - Wikipedia

   en.wikipedia.org/wiki/Biology

   Photosynthesis changes sunlight into chemical energy, splits water to liberate O 2, and fixes CO 2 into sugar. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organism's metabolic activities via cellular respiration.
