Which one of the following statements pertaining to plant structure is correct?

Options

A. cork lacks stomata, but letiticels carry out transpiration
B. passage cells help in transfer of food from cortex to phloem
C. sieve tube elemtnts possess cytoplasm but no nuclei
D. the shoot apical meristem has a quiescent centre

Answer

C

Explanation

Maturre cork cells are plant cells that form the protective water resistant tissue in the outer covering of stems and trunks. Cork cells are genetically programmed not to divide, but instead to remain as they are dead cells. Cork cells posses lenticels. A lenticel is produced beneath a former stomata or stoma of the epidermis. They encloses intercellular space for gaseous exchange. Passage cells help in transfer of water from cortex. Quiscent centre is present in root apical meristem.
