Which tissue type provides support, insulation, energy storage, and separation?

• A. Muscular tissue
• B. Epithelial tissue
• C. Nervous tissue
• D. Connective tissue

Answer: (D)

Support, insulation, energy storage, and separation are roles fulfilled by connective tissue. It provides the body's structural framework, connecting and supporting other tissues and organs. Adipose tissue, a type of connective tissue, stores fat for energy and offers insulation. Bones and cartilage, also connective tissues, give shape and mechanical support. Connective tissue also creates boundaries and partitions between organs and tissues, aiding separation. In contrast, muscular tissue is for movement, epithelial tissue lines surfaces and forms barriers, and nervous tissue handles communication and control. So the tissue that covers all four roles is connective tissue.
