Did you know there are organisms that are submicroscopic?

Really? I didn't think anything could be that small!

Root Explanation

Submicroscopic → It is formed from "sub-" (meaning under or below) and "microscopic" (from "micros" meaning small and "skopein" meaning to look or examine). The word "submicroscopic" refers to things that are too small to be seen with a standard microscope, thus existing below the level of microscopic visibility.

Memory Tip

Think of 'sub-' meaning 'under' and 'microscopic' meaning 'small enough to look at.' This helps you remember that 'submicroscopic' refers to things that are too small to be seen even with a microscope.
