The correct option is (c).
Explanation
Adipose tissue is a specialized type of loose connective tissue. Its primary function is the storage of energy in the form of lipids (fats). It plays a crucial role in homeostasis by acting as a caloric reservoir and a thermal insulator.
Statement-wise Analysis:
- Statement 1 is Correct: Adipose tissue is located mainly beneath the skin (subcutaneous layer), around internal organs (visceral fat), in bone marrow, and in breast tissue. It fills the spaces between organs and helps hold them in place.
- Statement 2 is Incorrect: The cells of adipose tissue, known as adipocytes, are specialized to store fats (lipids) in the form of globules. Calcium deposits are a characteristic feature of bone tissue (skeletal connective tissue), not adipose tissue.
- Statement 3 is Correct: Because fat is a poor conductor of heat, the layer of adipose tissue beneath the skin acts as an insulator. This helps reduce heat loss from the body and regulates body temperature. It also acts as a shock absorber to protect internal organs.
Key Takeaway:
Adipose tissue is a fat-storing connective tissue that provides thermal insulation and mechanical protection; it does not store calcium, which is a function of bone tissue.
