What type of protist is Volvox?

chlorophyte green algae
L. Volvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae. It forms spherical colonies of up to 50,000 cells. They live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700.

Is Volvox a protozoa?

Volvox is a colonial organism, a semi-transparent hollow sphere about the size of a pinhead, made up of 500 to 60,000 bi-flagellated cells embedded in a gelatinous wall. In sexual colonies, the gonidia are replaced by eggs or spermatozoa. …

Is Volvox a phytoplankton or zooplankton?

Vibrio cholerae is responsible for a large number of waterborne outbreaks (Alam et al., 2006) and has been detected both in the planktonic state and also attached to both abiotic and biotic surfaces that have included zooplankton (e.g. amoebae), phytoplankton (e.g. Volvox) and cyanobacteria.

Is Volvox eukaryotic or prokaryotic?

Volvox is a eukaryotic green algae. Algae of the genus Volvox are an example of the link between colonial organisms and multicellular organisms.

Is Volvox an algae or protozoa?

Volvox, genus of some 20 species of freshwater green algae (division Chlorophyta) found worldwide. Volvox form spherical or oval hollow colonies that contain some 500 to 60,000 cells embedded in a gelatinous wall and that are often just visible with the naked eye.

What kingdom is oscillatoria?

Oscillatoria
Oscillatoria princeps
Scientific classification
Domain: Bacteria
Phylum: Cyanobacteria

How do Volvocine algae move?

The volvocine algae include both unicellular and multicellular organisms that are closely related and exist today (Kirk 1998). Chlamydomonas are single-celled organisms with two apical flagella, which they use for sensory transduction and for moving around in a wet environment (Figure 2F).

Is Daphnia a zooplankton?

D. magna is a relatively large zooplankton species which makes it so vulnerable to fish predation that it is excluded from fish-inhabiting lakes. It occurs mainly in ephemeral habitats like small ponds and rockpools where vertebrate predators are rare.

Are marine cyanobacteria phytoplankton?

“Marine photosynthesis is dominated by microalgae, which together with cyanobacteria, are collectively called phytoplankton.” Phytoplankton are extremely diverse, varying from photosynthesising bacteria (cyanobacteria), to plant-like diatoms, to armour-plated coccolithophores.

What class does Oscillatoria belong to?

Cyanophyceae
Oscillatoria/Class

How many species of protozoa are there in the world?

Introduction. The Protozoa are considered to be a subkingdom of the kingdom Protista, although in the classical system they were placed in the kingdom Animalia. More than 50,000 species have been described, most of which are free-living organisms; protozoa are found in almost every possible habitat.

What is the name of the active stage of protozoa?

Trophozoite (Greek for “animal that feeds”) is a general term for the active, feeding, multiplying stage of most protozoa. In parasitic species this is the stage usually associated with pathogenesis.

How are locomotor organelles classified in a protozoa?

Another classification is based on the scheme given by the Committee on Taxonomy and Taxonomic Problems of the Society of Protozoologists, and mainly proposed by BM Honigberg and others (1964). It divides protozoa into four subphyla. Locomotor organelles are pseudopodia or flagella.

Why are protozoa important to the study of animals?

Regardless of their taxonomic status, the protozoa are an important assemblage of organisms with many members that exhibit animal-like characteristics. For this reason and because of their possible phylogenetic signifi­cance as possible ancestors of multicellular animals, they should be included in any course in general zoology.
