Question

What is the mode of nutrition in fungi?
A. Saprophytic
B. Holozoic
C. Parasitic
D. All of the above

Answer 1

A fungi or fungus is any member of the eukaryotic group, including microorganisms such as yeast and mold, and more commonly mushrooms. These organisms are classified as a kingdom, independent of other eukaryotic kingdoms, those being Plantae, Animalia, Protozoa, and Chromista. One characteristic that places fungi in a field different from plants, bacteria, and some protists is the chitin in their cell walls.

Complete answer:
Option A Saprophytic: The living organisms that live and feed on dead and decaying organisms are known as saprophytes. Saprophytic fungi feed on dead organic matter of plant and animal origin. Fungi directly absorb food through vegetative hyphae. Saprophytic fungi secrete exoenzymes that digest complex organics into simpler compounds in the substratum.
Since fungi has a saprophytic mode of nutrition, option A is correct.
Option B Holozoic: Holozoic nutrition can be defined as a method of nutrition that involves the digestion of several complex organic substances which can be in solid or liquid state. Fungi does include a holozoic mode of nutrition.
Hence option B is also correct.
Option C Parasitic: Parasitic nutrition or parasitism is a mode of heterotrophic nutrition in which one organism (called a parasite) lives on the surface of the body or inside the body of another living organism (called the host). The parasite feeds directly on the host's body.
Since fungi have a parasitic mode of nutrition, option C is also correct.
Option D All of the above: Since options A, B and C are true.

So, the correct answer is “Option D”.

Note:
Fungi, like animals, are heterotrophs; they obtain their food by absorbing soluble molecules, usually by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of transport, with the exception of spores (a few have flagella), which can travel through air or water. Fungi are the main decomposers of ecological systems. These and other differences place fungi in a group of related organisms.
