Verified step by step guidance

Understand that epithelial tissue is a type of tissue that lines the surfaces and cavities of organs and structures throughout the body.

Recognize that the jelly-like substance found between cells in tissues is part of the extracellular matrix (ECM), which provides structural and biochemical support to surrounding cells.

Learn that the ground substance is a key component of the ECM, consisting of water, glycosaminoglycans (GAGs), proteoglycans, and glycoproteins. It acts as a medium for nutrient and waste exchange between cells.

Differentiate the ground substance from other ECM components like collagen, elastin, and keratin. Collagen provides tensile strength, elastin allows tissues to stretch and recoil, and keratin is a structural protein found in skin, hair, and nails.

Conclude that the correct answer is 'Ground substance,' as it is the jelly-like material found between cells in epithelial tissue.
