Verified step by step guidance

Understand the function of transitional epithelium: It is specialized to accommodate fluctuation in the volume of the liquid in an organ, such as the bladder.

Recognize the structure of transitional epithelium: It consists of multiple layers of cells that can stretch and change shape, which is crucial for organs that need to expand and contract.

Differentiate from other epithelial types: Unlike a single layer of cube-shaped cells (simple cuboidal epithelium) or a single layer of flat cells (simple squamous epithelium), transitional epithelium is not limited to a single layer and is not primarily for secretion or diffusion.

Consider the presence of cilia: Transitional epithelium does not have cilia, which are typically found in pseudostratified columnar epithelium for moving mucus.

Conclude that the best description for transitional epithelium is 'Multiple layers of cells that can stretch and change shape', as it aligns with its function and structure.
