Which of the following is a category of microbial identification methods?

• A. Astronomical methods
• B. Morphological methods
• C. Geological methods
• D. Photosynthetic methods

Answer: (B)

Verified step by step guidance

1. Understand that microbial identification methods are techniques used to classify and identify microorganisms based on their characteristics.
2. Recognize that 'Morphological methods' refer to the study of the shape, size, and structure of microorganisms, which is a fundamental category in microbial identification.
3. Note that 'Astronomical methods' and 'Geological methods' are unrelated to microbiology and do not apply to microbial identification.
4. Understand that 'Photosynthetic methods' relate to the process by which organisms convert light energy into chemical energy, but this is not a standard category for identifying microbes.
5. Conclude that among the options, 'Morphological methods' is the correct category of microbial identification methods because it directly involves observing physical characteristics of microbes.
