  2. Streptocarpus ionanthus - Wikipedia

    en.wikipedia.org/wiki/Streptocarpus_ionanthus

    Saintpaulia ionantha H.Wendl. Saintpaulia kewensis C.B.Clarke. Saintpaulia tongwensis B.L.Burtt. Streptocarpus ionanthus ( synonym Saintpaulia ionantha) is a species of Streptocarpus in the section Saintpaulia, commonly known as an African violet. It is native to eastern and southwestern Tanzania. [2]

  3. Streptocarpus sect. Saintpaulia - Wikipedia

    en.wikipedia.org/wiki/Streptocarpus_sect._Saint...

    Streptocarpus sect. Saintpaulia is a section within Streptocarpus subgenus Streptocarpella [1] consisting of about ten species of herbaceous perennial flowering plants in the family Gesneriaceae, native to Tanzania and adjacent southeastern Kenya in eastern tropical Africa. The section was previously treated as a separate genus, Saintpaulia ...

  4. Plant development - Wikipedia

    en.wikipedia.org/wiki/Plant_development

    Plant development. Important structures in plant development are buds, shoots, roots, leaves, and flowers; plants produce these tissues and structures throughout their life from meristems [1] located at the tips of organs, or between mature tissues. Thus, a living plant always has embryonic tissues. By contrast, an animal embryo will very early ...

  5. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    The photosynthetic efficiency is the fraction of light energy converted into chemical energy during photosynthesis in green plants and algae. Photosynthesis can be described by the simplified chemical reaction. 6 H 2 O + 6 CO 2 + energy → C 6 H 12 O 6 + 6 O 2. where C 6 H 12 O 6 is glucose (which is subsequently transformed into other sugars ...

  6. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.

  7. Photophosphorylation - Wikipedia

    en.wikipedia.org/wiki/Photophosphorylation

    All organisms produce a phosphate compound, ATP, which is the universal energy currency of life. In photophosphorylation, light energy is used to pump protons across a biological membrane, mediated by flow of electrons through an electron transport chain. This stores energy in a proton gradient. As the protons flow back through an enzyme called ...

  8. Anoxygenic photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Anoxygenic_photosynthesis

    Anoxygenic photosynthesis is a special form of photosynthesis used by some bacteria and archaea, which differs from the better known oxygenic photosynthesis in plants in the reductant used (e.g. hydrogen sulfide instead of water) and the byproduct generated (e.g. elemental sulfur instead of molecular oxygen ).

  9. Petrocosmea - Wikipedia

    en.wikipedia.org/wiki/Petrocosmea

    Petrocosmea forrestii, leaf rosette. Petrocosmea is a genus of the family Gesneriaceae, the African violet family. Many of the species within this genus are endemic to high-elevation areas in Western China, [ 2] although some are native to other parts of Asia. [ 3] including north-central and southern China, Indochina, and the eastern Himalayas ...
