Which is more complex prokaryotes or eukaryotes cells

Eukaryotes

Explanation:

Eukaryotic cells have membrane bound organelles.

Prokaryotic cells do NOT have membrane bound organelles.

So, a Eukaryotic cell has structures such as a nucleus, mitochondria, a golgi complex, etc.  This provides the cells with distinct stuctures that have distinct functions.

consider the expression of a protein (protein synthesis.)  Transcription of the DNA into RNA happens within the nucleus.  The mRNA is sent from the nucleus to the cyctoplasm, where translation occurs at either the rough endoplasmic reticulum or the free floating ribosomes.

A prokaryotic cell has all of its machinery floating around inside its cytoplasm with no separation.    In these cells, transcription and translation both occur in the cytoplasm.  In fact, translation often begins before transcription is finished...
