Verified step by step guidance1
Understand the characteristics of epithelial tissue: Epithelial tissue is known for its specific features such as polarity, high cellularity, and avascularity.
Define polarity in epithelial tissue: Polarity refers to the presence of distinct structural and functional differences between the apical (top) and basal (bottom) surfaces of the cells.
Define high cellularity in epithelial tissue: High cellularity means that epithelial tissue is composed of tightly packed cells with minimal space between them.
Define avascularity in epithelial tissue: Avascularity indicates that epithelial tissue lacks blood vessels and receives nutrients through diffusion from underlying tissues.
Identify the feature that is not characteristic of epithelial tissue: Abundant extracellular matrix is not a feature of epithelial tissue, as epithelial tissue is characterized by minimal extracellular matrix compared to other tissue types like connective tissue.
