Fungi are typically grouped as:

Fungi are typically grouped as eukaryotic organisms because they possess cells with a nucleus and other membrane-bound organelles, which are defining characteristics of eukaryotes. Unlike prokaryotic organisms, such as bacteria, which lack a defined nucleus and organelles, fungi have a complex cellular structure that allows for greater specialization and functionality.

Additionally, fungi play crucial roles in ecosystems, such as decomposers that break down organic matter and recyclers of nutrients. While they do not perform photosynthesis like some other eukaryotic organisms (such as plants), they contribute to ecological balance in different ways, mainly through nutrient cycling. Their classification as eukaryotes highlights their evolutionary relationship with other kingdoms, including animals and plants, which possess similar cellular structures.
