  2. BThey are dead at maturity
  3. CThey possess vacuoles for storage of food
  4. DThey have cell wall which contains cellulose, pectin and hemicellulose

Correct answer

B. They are dead at maturity

Step-by-step solution

The collenchyma cells are polygonal or oval in shape. They have thickenings of pectin in the cell wall along with cellulose and hemicellulose. The collenchyma cells are found in the hypodermal layer of the dicot tissues. These cells have negligible intercellular spaces due to pectin deposition. Collenchyma is said to be the living mechanical tissue.
