Stored food in fungi is
(a)Starch
(b)Proteins
(c)Glycogen
(d)Chitin
Solution
This is made of many carbohydrates and is the chief storage polysaccharide of animal cells, bacteria, and most of the fungi. Fungi are heterotrophic organisms and obtain their nutrients by absorption.
Complete answer:
The stored food in fungi is in the form of glycogen and is also known as animal starch. Fungi get their nourishment from other sources as they are not capable of producing their food. Also, fungi have reserved food material in the form of oil globules.
Glycogen is a white powder in the dry state it is found in the form of granules in the cytoplasm in many cells. They play an important role in the glucose cycle as they form an energy reserve that can be quickly mobilized to connect an unexpected need for glucose. It is also used as a storage reserve in many parasitic protozoa.
Starch is a form of carbohydrate which is a water-insoluble polysaccharide and is the energy source stored in many plants. It has glucose units joined up together with certain bonds. Proteins can serve as a fuel source and are one of the building blocks of body tissue. They are macromolecules formed by amino acids. 20 different amino acids exist in proteins. The storage proteins serve as reserves of metal ions and amino acids and are found in plant seeds, egg whites, and milk. An example is the storage of iron by Ferritin.
Chitin is a fibrous substance consisting of polysaccharides which are the major constituents in the exoskeleton of arthropods such as crustaceans and insects, the scales of fish, and the cell walls of fungi. It functions as the supporting material for the cuticles of the epidermis, trachea, and the peritrophic matrices lining the gut epithelium.
So, the correct answer is 'Glycogen’.
Note: An organism that cannot manufacture its food and obtains its nutrition requirements from other sources of organic carbon mainly from plant or animal matter is known as a heterotroph organism. Examples are fungi, algae, and some types of bacteria.
