Which tissue stores fat?

Which tissue stores fat?

• A. Adipose Tissue
• B. Bone
• C. Muscle
• D. Cartilage

Answer: (A)

Adipose tissue is specialized for storing energy as fat. Its cells, adipocytes, contain large lipid droplets filled with triglycerides. This setup lets the tissue act as a concentrated energy reserve that can be mobilized when the body needs fuel, through a process called lipolysis that releases fatty acids and glycerol into the bloodstream. Beyond energy storage, adipose tissue also provides cushioning and insulation for the body. The other tissues have different primary roles. Bone supports the body and stores minerals, with marrow inside that can contain fat but isn’t the tissue’s main function. Muscle is built for movement and uses stored glycogen and supplied fats for energy, rather than serving as a primary fat reservoir. Cartilage provides flexible support and is avascular, not a fat storage site.
