Question: How does Albugo candida obtain nutrients?
Options:
Obligate parasite
Facultative parasite
Saprophyte
Facultative saprophyte
–
📌Other Options Explanations:
-(b) Faculative parasite: A facultative parasite can live on a host or independently.
-(c) Saprophyte: Saprophytes obtain nutrients from dead and decaying organic matter.
-(d) Facultative saprophyte: A facultative saprophyte can live on dead organic matter or as a parasite.
🔑Key Points:
-Albugo belongs to the Phycomycetes class of the Kingdom Fungi.
-The Kingdom Fungi constitutes unicellular or multicellular, eukaryotes, cosmopolitan, aquatic or terrestrial, heterotrophic organisms.
-Fungi are filamentous and their bodies consist of long, slender thread-like structures called hyphae.
-The network of hyphae is known as mycelium.
-Reproduction in fungi takes place by vegetative means of fragmentation, fission, and budding.
-Asexual reproduction is by conidia spores, sporangiospores, and zoospores, and sexual reproduction is by oospores, ascospores, and basidiospores.
-The morphology of the mycelium, mode of spore formation, and fruiting bodies form the basis for the division of the Kingdom into various classes namely-
-Phycomycetes
-Ascomycetes
-Basidiomycetes
-Deuteromycetes.
Important Points
-Nutritionally Albugo is an obligate parasite on plants.
-The parasites that entirely depend on a host for their food, shelter, and reproduction are known as obligate parasites.
-It is a parasite distributed all over the world.
-Their hyphae are aseptate, coenocytic, and profusely branched.
-It attacks mostly crucifers like turnips, mustard, radish, cabbage, cauliflower, etc.
-The disease is caused by Albugo commonly referred to as white rust as it appears as shiny, white, smooth, uneven pustules or blisters on the leaves, stems, and other aerial portions of the plants.
-The slow growth of lateral buds, darkening of flowers, distortion of floral parts, sterile gynoecium, etc. are the symptoms of severe infection of Albugo.
