What is the opposite of the prefix "micro"?

Small
Medium
Large
Tiny

The correct answer is: Large

The prefix "micro" is derived from the Greek word "mikros," meaning small or tiny. Therefore, its opposite would denote something that is larger in size. In this context, the term "large" accurately reflects the antonym of "micro," as it suggests a considerable size compared to the minute scale implied by "micro." The other terms, such as "small," "medium," and "tiny," either align with or suggest a size comparable to "micro," reinforcing the idea that those terms do not represent an opposite meaning. Understanding prefixes can greatly enhance your comprehension of terms in laboratory settings and their applications, and recognizing that "micro" refers to something very small helps clarify why "large" stands out as the opposite.
