Which of the following statements is incorrect regarding simple permanent tissues in plants?
Options
- AParenchyma cells are generally isodiametric and have thin cell walls made up of cellulose.
- BSclerenchyma consists of long, narrow cells with thick and lignified cell walls having a few or numerous pits.
- CCollenchyma provides mechanical support to the growing parts of the plant such as the young stem and petiole o
- DThe cells of collenchyma are much thickened at the corners due to the deposition of lignin and suberin.
Correct answer
D. The cells of collenchyma are much thickened at the corners due to the deposition of lignin and suberin.
Step-by-step solution
Parenchyma cells are generally isodiametric with thin cellulosic cell walls. Sclerenchyma consists of long, narrow cells with thick and lignified cell walls having a few or numerous pits. Collenchyma provides mechanical support to the growing parts of the plant such as the young stem and petiole of a leaf. The cells of collenchyma are much thickened at the corners due to the deposition of cellulose, hemicellulose, and pectin, not lignin and suberin. Thus, the statement regarding collenchyma having lignin and suberi
