Answer :
Final Answer:
The major features by which molds are routinely identified are Macroscopic characteristics and selective media.The correct answer is C) Macroscopic characteristics and selective media.
Explanation:
Molds are routinely identified based on macroscopic characteristics and selective media. Macroscopic characteristics involve the visible features of molds, such as color, texture, and growth pattern, which can be observed without the need for a microscope. Selective media are culture media designed to selectively encourage the growth of certain microorganisms while inhibiting others. In the context of mold identification, selective media can help isolate and identify specific mold species based on their growth patterns and reactions to different environmental conditions.
Macroscopic characteristics provide initial clues about the mold's identity, such as its appearance on the surface of a culture medium. The use of selective media further refines the identification process by creating conditions that favor the growth of particular molds. This approach helps distinguish between different mold species, allowing microbiologists to make accurate identifications. By combining macroscopic observations with selective media, the identification process becomes more precise and reliable.
In contrast to the other options, which involve either solely microscopic morphology, biochemical reactions, or specialized sexual reproductive structures, option C reflects a comprehensive and practical approach widely used in microbiology laboratories for mold identification. This method leverages both visible features and the influence of specific growth conditions to ensure a thorough and accurate identification process.
The correct answer is C) Macroscopic characteristics and selective media
