Is a centrioles found in all eukaryotics?

Centrioles are not found in all eukaryotes; they are primarily present in animal cells and some fungi and algae. Many higher plants and some protists lack centrioles entirely. Instead, these organisms utilize other structures for organizing microtubules during cell division. Thus, while centrioles play a key role in many eukaryotic cells, they are not a universal feature across all eukaryotic life.
