Vorticella is a genus of ciliate protozoa that is classified under the following: Kingdom: Chromalveolata. Phylum: Cilophora. Superphylum: Alveolata. Class: Oligohymenophorea. Subclass: Peritrichia. Order: Sessilida. Family: Vorticellidae. Reproduction and Life Cycle. Asexual Reproduction.
Vorticella es un género de protozoos del filo Ciliophora. Son microorganismos unicelulares ciliados de agua dulce eutrofizada, que viven en solitario o en grupos, y se fijan al sustrato con un pedúnculo contráctil. No son patógenos para humanos.
A quick overview. Classification of Vorticella. The cell structure of Vorticella. Mouth and Cilia. Food and Contractile vacuoles. Two nuclei. Spiral stalk. How does Vorticella live? – its characteristics and behavior. A Vorticella Bouquet is in fact a group of individual Vorticella. Vorticella feed by their cilia.
The constriction of the cytoplasm runs inward, each nucleus divides into two; the micronucleus by mitosis and the macronucleus by vegetative division; one new contractile vacuole, reservoir and anal spot appear and two identical daughter Vorticella are produced on the original stalk.
26 de dic. de 2016 · Vorticella is a suspension-feeding ciliate that lives in two forms: free swimming telotroch and sessile stalked trophont . A sessile Vorticella consists of the zooid (inverted-bell-shaped cell body; usually about 30–40 μm in diameter when contracted) and the stalk (3–4 μm in diameter and about 100 μm in length) (Figure 1 A).
Vorticella is a genus of bell-shaped ciliates that have stalks to attach themselves to substrates. The stalks have contractile myonemes, allowing them to pull the cell body against substrates. [1] . The formation of the stalk happens after the free-swimming stage. [2] Etymology.
Vorticella, genus of the ciliate protozoan order Peritrichida, a bell-shaped or cylindrical organism with a conspicuous ring of cilia (hairlike processes) on the oral end and a contractile unbranched stalk on the aboral end; cilia usually are not found between the oral and aboral ends.
