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.
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 ...
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.
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).
In addition to growth by cell division, a plant may grow through cell elongation. This occurs when individual cells or groups of cells grow longer. Not all plant cells grow to the same length. When cells on one side of a stem grow longer and faster than cells on the other side, the stem bends to the side of the slower growing cells as a result.
Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus.
Chlorella vulgaris has been the microalgae of choice for several bioremediation processes. Owing to its ability to remove a variety of pollutants such as inorganic nutrients (nitrate, nitrite, phosphate and ammonium), fertilizers, detergents, heavy metals, pesticides, pharmaceuticals and other emerging pollutants from wastewater and effluents, carbon dioxide and other gaseous pollutants from ...
Viridiplantae (lit. ' green plants ') [6] is a clade of around 450,000–500,000 species of eukaryotic organisms, most of which obtain their energy by photosynthesis.The green plants are chloroplast-bearing autotrophs that play important primary production roles in both terrestrial and aquatic ecosystems.
