Volvox is a genus of freshwater algae found in ponds and ditches, ... Volvox, one of the 7 Wonders of the Micro World by Wim van Egmond, from Microscopy-UK;
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. [3]
In Volvox only very few cells are able to reproduce new individuals, and in some species of Volvox the reproductive cells are derived from cells looking and behaving like somatic cells. In V. carteri , on the other hand, the division of labor is complete with reproductive cells being set aside during cell division, and they never assume somatic ...
Volvox is a genus of chlorophytes. Different species form spherical colonies of up to 50,000 cells. One well-studied species, Volvox carteri (2,000 – 6,000 cells) occupies temporary pools of water that tend to dry out in the heat of late summer
Volvox globator is a species of green algae of the genus Volvox. It was originally described by Carl Linnaeus in his 1758 work Systema Naturae. [1] In 1856 its sexuality was described by Ferdinand Cohn and is the same as Sphaeroplea annulina. [2] It is colonial flagellate found in freshwaters.
These include Volvox, a free-floating colonial alga which produces daughter colonies inside the maternal sphere, [7] and was first observed by one of the early microscopes by Leeuwenhoek in 1770. [8] Diatoms, desmids and many species of filamentous green algae such as Spirogyra are commonly found in shallow muddy areas.
The previous record for the smallest non-avian dinosaur egg, according to Guinness World Records, measures 45-by-20 millimeters (about 1.77-by-0.79 inches). Discovered in Japan's Tamba City, this ...
However, because the name Volvox had already been applied to a genus of flagellate algae, he later changed the name to Chaos chaos. In 1786, the Danish Naturalist Otto Müller described and illustrated a species he called Proteus diffluens , which was probably the organism known today as Amoeba proteus.
