Simple columnar epithelium is a single layer of cells. Stratified columnar epithelium has multiple layers, though only the apical (surface) cells are columnar in shape.
Yes, the distinct tall, narrow shape of the nuclei in columnar cells is clearly visible under a standard light microscope when tissue is properly stained.
The columnar shape provides a greater volume of cytoplasm per cell, which supports high metabolic activity for functions like secretion and absorption. It also allows for dense packing of organelles like mitochondria and Golgi apparatus.
Columnar epithelium is usually formal, academic, technical (biology/medicine) in register.
