Anew soil microorganism has been described. on some growth media, it forms colonies of unicellular organisms, but under certain conditions, it forms long, multicellular filaments and spores. the cells have nuclei, and their cell walls are composed of chitin.
to which of the following groups does this new organism belong?

a. protozoa
b. fungi
c. archaea
d. algae
e. bacteria

The correct answer is option B, that is, fungi.

Explanation:

The body of a fungus is formed of tiny tubes or filaments known as hyphae. It comprises nuclei and cytoplasm. A tangled mass of hyphae is known as mycelium, which enhances the surface area of the fungi to captivate more nutrients.  

Fungi are eukaryotic, most of the fungi are multicellular, while some are unicellular like yeast. The cell walls of fungi are formed of chitin in place of cellulose like that found in a plant.  Thus, the mentioned organism belongs to fungi category.
