Verified step by step guidance

Step 1: Understand the classification of epithelial tissue. Epithelial tissue is categorized based on the number of layers and the shape of the cells. Single-layered epithelium is referred to as 'simple,' while multi-layered epithelium is called 'stratified.'

Step 2: Examine the shape of the cells. Epithelial cells can be squamous (flat), cuboidal (cube-shaped), or columnar (tall and elongated). In this case, the problem specifies 'tall cells,' which indicates columnar cells.

Step 3: Rule out incorrect options. Pseudostratified columnar epithelium appears stratified but is actually a single layer with nuclei at different heights, which does not match the description of a single layer of tall cells. Stratified squamous epithelium consists of multiple layers of flat cells, which is also incorrect. Simple cuboidal epithelium consists of cube-shaped cells, not tall cells.

Step 4: Match the description to the correct classification. A single layer of tall cells is characteristic of simple columnar epithelium, which is specialized for absorption and secretion in areas like the digestive tract.

Step 5: Confirm the answer. Based on the description provided, the correct classification for an epithelium with a single layer of tall cells is 'simple columnar epithelium.'
