Question

Choose the correct answers from the alternatives given.
Which of the following cell types or structures is incorrectly paired with its meristematic tissue?

• A. Epidermis - protoderm
• B. Stele - procambium
• C. Cortex - ground meristem
• D. Secondary phloem - cork cambium

Answer 1

The correct option is D Secondary phloem - cork cambium

• Protoderm, procambium and ground meristem are part of meristematic tissue that are involved in continuous divisions and repairs the damaged parts.
  
• Dermal tissue system consists of epidermis and all the structures found in epidermis like root hairs, stomata, etc. The formation of this tissue system is the function of protoderm.
  
• The formation of the vascular tissue system is the function of procambium. The derivatives of procambium are primary phloem and primary xylem.
  
• Ground meristem represents the undifferentiated meristematic tissue of primary meristem. They divide frequently and the cells differentiate into cortex, pith and other tissues.
  
• Cork cambium forms secondary cortex. The secondary phloem is formed by the vascular cambium.
  

Hence, the correct answer is 'Secondary phloem - cork cambium'.
