A tissue sample contains cells scattered in an extracellular matrix with fibres and ground substance. Which feature supports its classification as connective tissue?
Correct answer: B. Cells are separated by matrix
- A. Cells form tightly packed layers
- B. Cells are separated by matrix
- C. Cells contract in regular waves
- D. Cells conduct rapid impulses
Explanation
Connective tissue is characterized by cells distributed within an extracellular matrix containing ground substance and fibres. Tightly packed layers describe epithelium, while contraction and impulse conduction describe muscle and nervous tissue.
