Verified step by step guidance

Understand the structure of columnar epithelial cells: Columnar epithelial cells are elongated and column-shaped, which distinguishes them from other epithelial cell types like squamous (flat) and cuboidal (cube-shaped) cells.

Identify the unique features of columnar epithelial cells: One of the key characteristics of columnar epithelial cells is that they may contain goblet cells, which are specialized for secreting mucus.

Differentiate columnar cells from other epithelial tissues: While other epithelial tissues may also have secretory functions, the presence of goblet cells is a distinctive feature of columnar epithelial tissue.

Consider the functions of columnar epithelial tissue: Columnar epithelial tissue is often involved in absorption and secretion, particularly in the digestive tract, where goblet cells play a crucial role in producing mucus to protect and lubricate the lining.

Review the options provided: The statement 'Columnar epithelial tissue may contain goblet cells' is true and specific to columnar epithelial tissue, setting it apart from other types of epithelial tissues.
