Which of the following is a major difference between cartilage and other types of connective tissues? 
  1. The extracellular matrix in cartilage lacks collagen.
  2. Cartilage does not contain blood vessels.
  3. The primary mineral in cartilage is phosphorus rather than calcium.
  4. Cartilage cells do not possess nuclei.
Explanation
Correct Response: B. Connective tissues join and/or support other tissues within the body and include such tissues as adipose tissue, bone, and cartilage. Cartilage is unique among connective tissue in that it does not contain blood vessels. Collagen (A) is an important structural component of cartilage. Unlike bone, cartilage is not a significant reservoir of either phosphorus or calcium (C). Chondrocytes, or cartilage cells, contain nuclei (D).
