The Correct Option is A

Solution and Explanation

Mushroom, smut and rust are fungi which belong to class- Basidiomycetes of division-Basidiomycotina. Basidiomycetes is characterised with about sixteen thousand described species.

Kingdom Fungi - Edible Fungus

Fungi (singular: fungus or funguses) are eukaryotic organisms classified under the kingdom Fungi. These organisms can be single-celled or multicellular. They include organisms, particularly yeasts, mushrooms, and molds. The eukaryotic microorganisms possess a cell wall made of chitin and polysaccharides. With that, they can be found anywhere and are classified as heterotrophs

The nucleus they keep is surrounded by a nucleus membrane and is dense, clear, and also contains chromatin threads. The existence of fungi can be seen as black spots found on bread, mushrooms, and yeast cells. These microorganisms are also responsible for fungal and skin diseases. 

  • Based on the mode of nutrition, fungi can be classified as Saprophytic, Parasitic, and Symbiotic. 
  • Based on spore formation, fungi can be classified as Zygomycetes, Ascomycetes, Basidiomycetes, and Deuteromycetes.

Following are the important features of fungi:

  • Fungi are multicellular organisms that have a cell wall, organelles, and a nucleus but no chloroplasts.
  • They lack locomotion mechanisms. Fungi can range in size from microscopic to massive ( such as mushrooms).
  • The process of obtaining nutrients is known as absorption.
  • Fungi, for the most part, get their nutrients from decaying matter.
