Definition

A large, thick-walled cell found in some cyanobacteria that helps in the process of nitrogen fixation.

Example

The heterocyst plays a crucial role in the nitrogen cycle by converting atmospheric nitrogen into a usable form for plants.

Conversation

Have you ever heard of a heterocyst?

Yeah, I think it's that special cell in cyanobacteria, right?

Exactly! It's where nitrogen fixation happens, which is pretty cool.

Totally, those cells are fascinating and so important for ecosystems.

Root Explanation

Heterocyst → It is formed from "hetero-" (from Greek "heteros", meaning different) and "cyst" (from Greek "kystis", meaning bladder or sac). The word refers to a specialized cell that is different in structure and function, typically found in certain algae and cyanobacteria, which serves a specific purpose in nitrogen fixation.

Memory Tip

Think of 'different' ('hetero-') cells that act like 'sacs' ('cyst') for a special function in some algae — that's what a heterocyst is.
