Which tissue type primarily stores energy as fat and provides insulation?

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

Answer: (C)

Energy storage and insulation come from adipose tissue, a specialized form of connective tissue. Adipose tissue is made up of fat-storing cells called adipocytes that hold fat as triglycerides. This stored fat serves as an energy reserve and also creates an insulating layer under the skin and around organs, helping to regulate temperature and cushion structures. Because adipose tissue is classified within the connective tissue family, the overall tissue type that primarily stores energy as fat and provides insulation is connective tissue. The other tissue types have different roles: nervous tissue transmits signals, epithelial tissue forms coverings and linings, and muscular tissue contracts to produce movement.
