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 ...
Cladophora coloring is bright green which reflects the chlorophyll a, and chlorophyll b, which are similar to higher plant ratios and that also contains β-carotene and xanthophylls. [3] The thallus branches are smaller than the main axis, dichotomous, rough in texture, and have narrow tips.
Volvox carteri [1] is a species of colonial green algae in the order Volvocales. [2] The V. carteri life cycle includes a sexual phase and an asexual phase.V. carteri forms small spherical colonies, or coenobia, of 2000–6000 Chlamydomonas-type somatic cells and 12–16 large, potentially immortal reproductive cells called gonidia.

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.
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
When on the ground, they’re even slower and crawl about one foot per minute. If a sloth were to sprint, it could only go about 1.5 miles per hour. Because of the sloth’s slow nature and the ...
Carbohydrate content can range from 3.6 - 83.2% of dry matter depending on the species. [24] The main pigments of Caulerpa are chlorophyll a and b. [20] It has a high diversity of chemical compounds which have pharmaceutical potential. Although the genus is known to exhibit high toxicity, it was found to be of low risk to humans. [29]
Genera such as Rhynia have a similar life-cycle but have simple tracheids and so are a kind of vascular plant. [44] It was assumed that the gametophyte dominant phase seen in bryophytes used to be the ancestral condition in terrestrial plants, and that the sporophyte dominant stage in vascular plants was a derived trait.
