The identities of microorganisms on our planet
- a. are mostly known.
- b. have nearly all been identified via microscopy.
- c. have nearly all been identified via culturing techniques.
- d. are still mostly unknown.

Introduction:
The diversity of microbes is very vast and diverse. Identification of new microbes is still studied and various researches have conducted the identification of new strains or species. Various physical and chemical tests are performed to determine the metabolic functions which are specific to species of microbes.
Answer to Problem 1Q
Correct answer:
The identities of various microbes are still unknown on the planet Earth. Therefore, option (d) is correct.
Option (d) is given as “are still mostly unknown”.
Explanation of Solution
Justify reasons for the correct statement:
All the microorganisms present on the planet are not known. There are many species present on the planet Earth which have not been discovered to date. The planet is very diverse and various species and strains of microbes are present in it.
Hence, option (d) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “are mostly known”.
No, all the species on the planet have not been identified. Hence, it is a wrong answer.
Option (b) is given as “have nearly all been identified via microscopy”.
Microscopy is the technique used for the identification of microorganisms. Hence, it is a wrong answer.
Option (c) is given as “have nearly all been identified via culturing techniques”.
Culturing is used to grow microorganisms and not for identification. Hence, it is a wrong answer.
Hence, options (a), (b), and (c) are incorrect.
Microbiologists claim that many microorganisms present on the planet have not been identified yet. There are so many species of microbes which are unidentified.
