What is the primary function of adipocytes within connective tissue?
Solution
Correct Answer: Option B
The primary function of adipocytes within connective tissue is to store lipids. Adipocytes, also known as fat cells, are specialized cells that have the unique ability to accumulate and store large amounts of triglycerides in the form of lipid droplets. This lipid storage serves as an important energy reserve for the body and also provides insulation and cushioning to protect organs.
To clarify the other options:
- Synthesize collagen fibers is mainly the role of fibroblasts, which produce the structural proteins necessary for the connective tissue matrix.
- Produce extracellular matrix is a general function of several connective tissue cells, including fibroblasts, but not adipocytes predominantly.
- Phagocytose cellular debris is a function of macrophages, which act as immune cells within connective tissue to clear debris and pathogens.
Therefore, adipocytes are primarily concerned with lipid storage, making Option 2 the correct answer.
