Simplified diagram of a chlorophyte cell combining structures seen across the phylum: 1) flagellum; 2) synistosome with fibers adhering to a pair of basal bodies; 3) basal body; 4) microtubular rootlet belonging to the "X-2-X-2" arrangement, in this case 4-2-4-2 (only front-facing rootlets are shown); 5) flagellar pit (only two of four flagella ...
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.

Volvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae. Volvox species form spherical colonies of up to 50,000 cells, and for this reason they are sometimes called globe algae.
The Archaeplastida (or kingdom Plantae sensu lato "in a broad sense"; pronounced / ɑːr k ɪ ˈ p l æ s t ɪ d ə /) are a major group of eukaryotes, comprising the photoautotrophic red algae (Rhodophyta), green algae, land plants, and the minor group glaucophytes. [6]
Volvocine algae range from the unicellular Chlamydomonas to the multicellular Volvox through various intermediate forms and are used as a model for research into the evolution of multicellularity. The spheroidal colony is thought to have evolved twice independently within this group: once in the Volvocaceae, from Pandorina to Volvox, and the ...
Life forms: (1) Phanerophyte, (2; 3) Chamaephyte, (4) Hemicryptophyte, (5; 6) Geophyte, (7) Helophyte, (8; 9) Hydrophyte. Therophyte and epiphyte are not shown. The Raunkiær system is a system for categorizing plants using life-form categories, devised by Danish botanist Christen C. Raunkiær and later extended by various authors.
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]
Ankistrodesmus is a genus of green algae in the family Selenastraceae. [1] It is one of the most common types of phytoplankton in freshwater habitats around the world. [ 3 ] The name Ankistrodesmus comes from the Greek roots ankistron , meaning "cross", and desmos , meaning "bond".
