  2. Bryophyte - Wikipedia

    en.wikipedia.org/wiki/Bryophyte

    Bryophytes (/ ˈ b r aɪ. ə ˌ f aɪ t s /) [2] are a group of land plants (embryophytes), sometimes treated as a taxonomic division, that contains three groups of non-vascular land plants: the liverworts, hornworts, and mosses (Bryophyta sensu lato). [3]

  3. Plant - Wikipedia

    en.wikipedia.org/wiki/Plant

    The photosynthesis conducted by land plants and algae is the ultimate source of energy and organic material in nearly all ecosystems. Photosynthesis, at first by cyanobacteria and later by photosynthetic eukaryotes, radically changed the composition of the early Earth's anoxic atmosphere, which as a result is now 21% oxygen .

  4. Biological soil crust - Wikipedia

    en.wikipedia.org/wiki/Biological_soil_crust

    Cyanobacteria are the main photosynthetic component of biological soil crusts, [4] in addition to other photosynthetic taxa such as mosses, lichens, and green algae. The most common cyanobacteria found in soil crusts belong to large filamentous species such as those in the genus Microcoleus. [3]

  5. Algae - Wikipedia

    en.wikipedia.org/wiki/Algae

    Algae have photosynthetic machinery ultimately derived from cyanobacteria that produce oxygen as a byproduct of splitting water molecules, unlike other organisms that conduct anoxygenic photosynthesis such as purple and green sulfur bacteria. Fossilized filamentous algae from the Vindhya basin have been dated to 1.6 to 1.7 billion years ago. [11]

  6. Moss - Wikipedia

    en.wikipedia.org/wiki/Moss

    Chloroplasts (green discs) and accumulated starch granules in cells of Bryum capillare. Botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are usually small (a few centimeters tall) herbaceous (non-woody) plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis.

  7. Embryophyte - Wikipedia

    en.wikipedia.org/wiki/Embryophyte

    Most bryophytes, such as these mosses, produce stalked sporophytes from which their spores are released. The non-vascular land plants, namely the mosses (Bryophyta), hornworts (Anthocerotophyta), and liverworts (Marchantiophyta), are relatively small plants, often confined to environments that are humid or at least seasonally moist.

  8. Hornwort - Wikipedia

    en.wikipedia.org/wiki/Hornwort

    The sporophyte in hornworts is unique among bryophytes in being long-lived with a persistent photosynthetic capacity. [16] The sporophyte lacks an apical meristem, an auxin-sensitive point of divergence with other land plants some time in the Late Silurian/Early Devonian. [17] [18]

  9. Nostoc punctiforme - Wikipedia

    en.wikipedia.org/wiki/Nostoc_punctiforme

    Nostoc punctiforme is a species of filamentous cyanobacterium.Under non-limiting nutritional environmental conditions, its filaments are composed of photosynthetic vegetative cells; upon nutrient limitation, some of these cells undergo differentiation into heterocysts, akinetes or hormogonia.
