Root Explanation

Heterothallism → It is formed from "hetero-" (from Greek "heteros", meaning different) and "thallus" (from Greek "thallos", meaning a young shoot or twig). The term describes a reproductive strategy in fungi and algae where different mating types are required for sexual reproduction, hence the concept of 'different' ('hetero-') reproductive structures ('thallus').

Memory Tip

Think of 'different' ('hetero-') reproductive types in organisms that need to come together to reproduce, which is what heterothallism describes.
