  2. Chlamydomonas - Wikipedia

    en.wikipedia.org/wiki/Chlamydomonas

    All Chlamydomonas are motile, unicellular organisms. Cells are generally spherical to cylindrical in shape, but may be elongately spindle-shaped, [9] and a papilla may be present or absent.

  3. Chlorophyta - Wikipedia

    en.wikipedia.org/wiki/Chlorophyta

    Chlorophytes are eukaryotic organisms composed of cells with a variety of coverings or walls, and usually a single green chloroplast in each cell. [4] They are structurally diverse: most groups of chlorophytes are unicellular, such as the earliest-diverging prasinophytes, but in two major classes (Chlorophyceae and Ulvophyceae) there is an evolutionary trend toward various types of complex ...

  4. Floral diagram - Wikipedia

    en.wikipedia.org/wiki/Floral_diagram

    A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.

  5. Chlorophyceae - Wikipedia

    en.wikipedia.org/wiki/Chlorophyceae

    Depending on the species, Chlorophyceae can grow unicellular (e.g. Chlamydomonas), colonial (e.g. Volvox), filamentous (e.g. Ulothrix), or multicellular. [example needed] They are usually green due to the presence of chlorophyll a and chlorophyll b; they can also contain the pigment beta-carotene.

  6. Halimeda opuntia - Wikipedia

    en.wikipedia.org/wiki/Halimeda_opuntia

    Halimeda opuntia is found in the Indo-Pacific Ocean, the Atlantic Ocean, the Mediterranean Sea, [4] and the Caribbean Sea and around the coasts of Florida and the Bahamas. It grows in grooves, depressions and cracks in rocks and between coral heads in moderately protected parts of the reef, at depths down to about 55 m (180 ft).

  7. Floral morphology - Wikipedia

    en.wikipedia.org/wiki/Floral_morphology

    Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces. [note 1]

  8. Viridiplantae - Wikipedia

    en.wikipedia.org/wiki/Viridiplantae

    Both the "chlorophyte algae" and the "streptophyte algae" are treated as paraphyletic (vertical bars beside phylogenetic tree diagram) in this analysis. [ 22 ] [ 23 ] The classification of Bryophyta is supported both by Puttick et al. 2018, [ 24 ] and by phylogenies involving the hornwort genomes that have also since been sequenced.

  9. Plant development - Wikipedia

    en.wikipedia.org/wiki/Plant_development

    On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate. Plant growth and development are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al. 1983). [10]
