Question

Identify the incorrect statement regarding fungi.
(a) Some of the factors affecting fungi are temperature, moisture
(b) Fungi are mainly terrestrial
(c) Fungi show diversity in habitat and morphology
(d) Fungi are more abundant in the substrate with low sugar content and low temperature

Answer 1

Hint: Fungi are eukaryotic organisms which are predominantly microscopic. The examples of different fungi include single celled yeast, bread mold to macroscopic mushrooms. They contain a cell wall made of chitin.

Complete answer:
For more abundant growth, the fungi need substrate with high sugar content to act as the nutrient source. The growth is also high in high temperature ranges that are from 25 to 30 degree Celsius.
Considering the other given statements:
The key determinants of fungal growth is the presence of moisture and also an optimum temperature range. The fungal growth is accelerated by the presence of moisture. Thus some of the factors affecting fungi are temperature and moisture. Thus it is a correct statement.
Most of the members of kingdom fungi occupy the terrestrial region, the majority of which grow on dead and decaying organic substances. Other members can exist in a parasitic or symbiotic relationship with other plants or animals. Thus it is a correct statement.
The fungal members can survive in a variety of habitats, like dead and decaying organisms, as parasites in higher organisms or in a symbiotic relationship. Thus it is a correct statement.
Hence from the given statements, the incorrect one is d.

So, the correct answer is “Option d”.

Note:
The nutrients in fungi are saprophytic in nature. That is they are heterotrophic and depend on other organisms to derive nutrition. And fungi has many commercial applications. Yeast cells are utilized in baking and brewing industries. The antibiotic Penicillin is derived from a fungus. And various fungi in the form of mushrooms are edible.
