What are facultative Saprophytes?
What are facultative Saprophytes?
A facultative saprophyte is an organism that generally obtains nourishment from the living matter, but can obtain nourishment even from dead organic matter too.
What is meant by facultative parasites?
Facultative Parasite A parasitic organism that requires the host organism to complete its life cycle is known as an obligate parasite. A parasitic organism that is able to complete and continue its life cycle even in the absence of the host is known as a facultative parasite.
Which of the following pathogen is facultative saprophyte?
The correct answer is (A). Facultative saprophyte is a parasite which can live as a saprophyte. Note: Saprophytes decompose dead and decaying organisms by the help of digestive juices which break the complex biomolecules of the dead organism.
What is obligate saprophyte?
An obligate saprophyte is an organism that relies completely on dead matter. A parasite which becomes saprophytic in the absence of host is called facultative saprophyte.
What does facultative and obligate mean?
Facultative: Facultative refers to the ability to live under more than one specific environmental condition. Obligate: Obligate means to be restricted to a particular characteristic.
What is the difference between facultative and obligate parasite?
If an obligate parasite cannot obtain a host it will fail to reproduce. This is opposed to a facultative parasite, which can act as a parasite but does not rely on its host to continue its life-cycle. Obligate parasites have evolved a variety of parasitic strategies to exploit their hosts.
What is the difference between facultative Saprophyte and facultative parasite?
Facultative organisms can live on organic residues as saprophytes; but they can also infect living plants as parasites when conditions are favorable. Those organisms that live primarily saprophytes are called facultative parasites. Those organisms that live primarily as parasites are called facultative saprophytes.
What is obligate and facultative?
A facultative anaerobe is an organism that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen is absent. An obligate aerobe, by contrast, cannot make ATP in the absence of oxygen, and obligate anaerobes die in the presence of oxygen.
Is Fusarium a facultative saprophyte?
A large number of Fusarium spp. are entomopathogenic; some are weak, facultative pathogens, especially of the lepidopteran and coleopteran orders, and they will colonize their dead hosts as saprophytes.
What are the examples of facultative parasite?
Facultative parasites, in turn, are free-living but they may become parasitic if there is an opportunity to infect a host. An example of a facultative parasite is Naegleria fowleri, a free-living amoeba that on some occasions may infect humans. Is a virus a parasite? Viruses are obligate parasites.
What does facultative mean in biology?
Biology. having the capacity to live under more than one specific set of environmental conditions, as a plant that can lead either a parasitic or a nonparasitic life or a bacterium that can live with or without air (opposed to obligate).
What are the differences between a facultative parasite and a facultative Saprophyte?
