Which of the following is not considered a microorganism?
- a. alga
- b. bacterium
- c. protozoan
- d. mushroom
Introduction:
The microscopic organisms occur as “uni-or multi-cellular” along with cluster of cells. There are various species of microorganisms covering almost the Earth. The microorganisms are divided into major types: “viruses”, “archaea”, “bacteria”, “fungi”, “protozoa”, and “algae”. The microorganisms are not generally seen from naked eyes.
Answer to Problem 1MCQ
Correct answer:
The microorganisms do not include mushroom.
Therefore, option (d) is correct.
Option (d) is given as “mushroom”.
Explanation of Solution
Justify reasons for the correct statement:
The fruiting body of a fungus that bears spores is termed as mushroom and is visible by naked eyes. This denies the definition of microorganism.
Hence, option (d) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “algae”.
The algal species are microscopic in nature. Hence, it is a wrong answer.
Option (b) is given as “bacterium”.
The bacterium is microscopic in nature. Hence, it is a wrong answer.
Option (c) is given as “protozoa”.
The protozoan species are microscopic in nature. Hence, it is a wrong answer.
Hence, options (a), (b), and (c) are incorrect.
The algae, protozoan, and bacteria are included in microorganism, while mushroom is not included in microorganism.
