Question

An injured plant part is repaired with the help of

• A. Lateral meristem
• B. Primary meristem
• C. Intercalary meristem
• D. Apical meristem

Answer 1

Answer: (A)

Lateral meristem

• A mass of cells (callus) grows over the injured surface of a wound to heal and repair.
• When any part of a plant gets injured a wound is formed in that region.
• The wound is raised due to the formation of callus which is composed of parenchyma cells.
• These living parenchyma cells of wound forms a cambium (wound cambium) which also known as an inducible cambium.
• This wound cambium forms cork towards the outer side which covers the wound entirely formed from a secondary lateral meristem.
• So, the correct answer is 'Lateral meristem'
