MCQ practice · SSC Biology Board questions · Chapter 2: Cells and Tissues of Organisms
In tissue 'A' the matrix is plentiful, cells are few and are scattered in the matrix. The work of tissue 'A':
- i. taking part in making the pump organ for blood circulation
- ii. giving the body a fixed shape and firmness
- iii. carrying various substances inside the body
Think it through first, then pick an option.
- a i and ii
- b i and iii
- c ii and iii
- d i, ii and iii
Answer and explanation
Correct answer: c ii and iii
ii and iii are true: connective tissue gives shape and firmness (skeletal) and carries substances (fluid).
Why the other options are wrong
- a i and ii: i is wrong: the pump for blood circulation is built of cardiac muscle, not by connective tissue.
- b i and iii: i is wrong, so this pair is not right. The right answer here is: ii and iii.
- d i, ii and iii: i is wrong, so all three cannot be true together.
