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).
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 ...
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.
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.
The flowers are small and usually white, produced on sparse panicles up to 120 cm (47") long. In certain species, such as C. comosum (the ubiquitous 'spider plant'), the plants are known to reproduce vegetatively by producing plantlets —baby plants connected by an "umbilical" stem, sprouting from the side of the main mother-plant.
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.

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.
Chlorella is a genus of about thirteen species of single-celled or colonial green algae of the division Chlorophyta.The cells are spherical in shape, about 2 to 10 μm in diameter, and are without flagella.
