Protists are a diverse collection of organisms. While exceptions exist, they are primarily microscopic and unicellular, or made up of a single cell. The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles.

Do protists have a nucleus and DNA?

Like all other eukaryotes, protists have a nucleus containing their DNA. They also have other membrane-bound organelles, such as mitochondria and the endoplasmic reticulum.

Do all protists have a true nucleus?

One such membrane bound organelle is a nucleus, which all protists (regardless of whether they are more 'animal-like', 'plant-like', or 'fungus-like') do possess.
