Volvox is a polyphyletic genus in the volvocine green algae clade. [2] Each mature Volvox colony is composed of up to thousands of cells from two differentiated cell types: numerous flagellate somatic cells and a smaller number of germ cells lacking in soma that are embedded in the surface of a hollow sphere or coenobium containing an ...
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.

Multiple sources give different estimates of the area enclosed by the imaginary border of Asia. The New York Times Atlas of the World gives 43,608,000 km 2 (16,837,000 sq mi). [1] Chambers World Gazetteer rounds off to 44,000,000 km 2 (17,000,000 sq mi), [2] while the Concise Columbia Encyclopedia gives 44,390,000 km 2 (17,140,000 sq mi). [3]
Pandorina is a genus of green algae composed of 8, 16, or sometimes 32 cells, held together at their bases to form a sack globular colony surrounded by mucilage.The cells are ovoid or slightly narrowed at one end to appear keystone- or pear-shaped.

Protista is still a kingdom. Monera, however, is now two kingdoms, Archaebacteria and Eubacteria. Also, many protists are plant-like while some are animal-like or fungi-like, but belong in none of these three kingdoms. Volvox is a green algae, which are plant-like protists. Volvox also does not have many of the characteristics of a plant.
