Which of the following statements is incorrect regarding this?

• A. P can be root apical meristem which is generally sub-terminal in position
• B. Q can be phloem which is also called bast
• C. R can be parenchyma which comprises of thin walled isodiametric cells
• D. S can be collenchyma which is a living mechanical tissue

Answer 1

Answer: (D)

P could be meristematic tissues which possess the ability to grow and divide. Q could be phloem which contains only one type of dead cells i.e., phloem fibres, other types of cells of phloem are living. R could be parenchyma which is chiefly a storage tissue. S could be sderenchyma which is a dead mechanical tissue and possesses uniform lignified wall thickenings. Collenchyma possesses localised wall thickenings of cellulose or pectocellulose
