Which connective tissue stores fat?

• A. Tendon
• B. Cartilage
• C. Adipose tissue
• D. Blood

Answer: (C)

Fat storage happens in adipose tissue, a specialized loose connective tissue made up of adipocytes that hold large lipid droplets. These cells store triglycerides, which the body can tap into for energy when needed. Adipose tissue also cushions and insulates the body, and there are two main types: white adipose tissue (energy storage) and brown adipose tissue (heat generation). You’ll find adipose tissue under the skin, around internal organs, and in bone marrow, among other places.

Tendon is dense connective tissue that connects muscle to bone and transmits force. Cartilage is a supportive tissue with a rubbery matrix that cushions joints. Blood is a fluid connective tissue that transports gases, nutrients, and waste. None of these primarily stores fat like adipose tissue does.
