Which tissue type provides binding, support, and energy storage?

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

Answer: (B)

Binding tissues together, providing structural support, and storing energy describe the role of connective tissue. Its extracellular matrix, with fibers like collagen and elastin and a ground substance, forms the framework that holds organs in place and distributes mechanical forces. Different cells live in this matrix—fibroblasts produce the matrix, adipocytes store fat, and bone and cartilage cells maintain mineralized or resilient structures. The energy-storage aspect comes from adipose tissue, a type of connective tissue that packs away fat droplets for later use and also cushions and insulates. You can see connective tissue in bones and cartilage that support and protect, in tendons and ligaments that connect tissues, and in blood that transports nutrients. In contrast, epithelial tissue lines surfaces and protects, nervous tissue transmits signals, and muscle tissue contracts to move.
