Q. Which of the following are correctly matched?

1. Bone cells – embedded in a hard matrix composed of calcium and phosphorus
2. Tendons – very elastic
3. Cartilage – matrix composed of proteins and sugars
4. Areolar tissue – helps in repair of tissue

Select the correct option from the codes given below:
Answer: Only 1, 3 and 4
Notes: Bone cells are set in a matrix of calcium and phosphorus. Tendons connect muscles to bones, are strong but not very elastic. Cartilage has a matrix of proteins and sugars, providing flexibility. Areolar tissue supports organs, fills internal spaces, and aids tissue repair. Therefore, only statements 1, 3, and 4 are correct.
