Which of these is/are considered lateral meristem(s) ?
A) apical meristems only
B) vascular cambium only
C) cork cambium only
D) pericycle and periderm
E) vascular cambium and cork cambium
Lateral Meristem
Plant tissue located in the stem and root that enables growth in thickness or girth in a maturing plant.
Vascular Cambium
A layer of plant tissue located between the xylem and the phloem that is responsible for the secondary growth of stems and roots, allowing them to increase in thickness.
Cork Cambium
A layer of tissue in plants that produces cork (phellem) cells for protection and waterproofing.

Final Answer :
E
Explanation :
The vascular cambium and cork cambium are both considered lateral meristems because they are responsible for secondary growth in plants, meaning they increase the girth of stems and roots. The apical meristem is responsible for primary growth, meaning it promotes the lengthening of stems and roots. The pericycle and periderm are not considered lateral meristems.
