Definition

The larger nucleus found in certain single-celled organisms, which manages the cell's everyday activities like metabolism and growth.

Example

In ciliate protozoans, the macronucleus plays a crucial role in regulating metabolic processes.

Conversation

Did you know that a ciliate has a structure called a macronucleus?

Really? What does it do exactly?

It controls the cell's nonreproductive functions, like metabolism.

That's fascinating! I had no idea they had such complex systems.

Root Explanation

Macronucleus → It is formed from "macro-" (from Greek "makros", meaning large) and "nucleus" (from Latin "nucleus", meaning kernel or core). The word "macronucleus" refers to a large nucleus, typically found in certain protozoa, that is involved in the regulation of cellular activities.

Memory Tip

Think of 'large' ('macro-') and 'core' ('nucleus') to remember that a macronucleus is a large core of a cell.
