Can anyone tell me if a small intestine epithelial cell from the small intestine has any of the following organelles: golgi apparatus, mitochondrion, nuclear envelope, plasmid or ribosomes. Thanks!

These are columnar cells with nucleus in the basal half, mitochondria almost parallel to the longitudinal axis, well developed Golgi, and ribosomes mostly in the basal half. No plasmid.

Epithelial cells are eukaryotic cell, therefore it has every organelle you mentioned, except the plasmid, as plasmid are prokaryotic organelle important for genetic exchange. Prokaryotic cells do not have nuclear envelope nor mitochondria if you are interested. It has been speculated that mitochondria was evolved from bacteria.

It has everything except a plasmid. Eukaryotic cells usually do not have plasmids, and if they are forced to take up a plasmid (by transfection, for example), the plasmids are not retained long.
