Which tissue type stores energy in the body?

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

Answer: (B)

Energy storage in the body is handled primarily by adipose tissue. Adipose tissue is made up of adipocytes that hold large lipid droplets, allowing them to store triglycerides for long-term energy. This fat reserve is highly energy-dense—about 9 kcal per gram—so it serves as a compact supply that can be mobilized when food is scarce or during extended activity, while also providing insulation and cushioning.

Epithelial tissue forms barriers and lines surfaces, not energy stores. Nervous tissue consumes energy to function but does not store it; its role is signaling and processing information. Muscle tissue does store some energy as glycogen to fuel contractions, but this is a comparatively smaller, readily accessible reserve, not the body’s primary storage site. So, adipose tissue best fits the role of storing energy in the body.
