Stratified squamous epithelium

Transitional epithelium

Simple cuboidal epithelium

Verified step by step guidance

Understand the function of the tissue type: Diffusion and filtration are processes that require minimal barriers for substances to pass through. This suggests the tissue type must be thin and permeable.

Review the structure of epithelial tissues: Simple squamous epithelium consists of a single layer of flat cells, which is ideal for diffusion and filtration due to its thinness. Other types, such as stratified squamous epithelium, are multilayered and designed for protection, not diffusion.

Compare the options: Stratified squamous epithelium is multilayered and protective, transitional epithelium is specialized for stretching, and simple cuboidal epithelium is a single layer of cube-shaped cells designed for secretion and absorption. None of these are specialized for diffusion and filtration.

Focus on the correct option: Simple squamous epithelium is the only tissue type listed that matches the description of being a single layer of flat cells specialized for diffusion and filtration.

Conclude the reasoning: Based on the structure and function of epithelial tissues, the correct answer is 'Simple squamous epithelium.'
