Questions & Step-by-Step Solutions

What type of cells are responsible for the secondary growth in plants?
Correct Answer: Lateral meristem
  • Step 1: Understand that plants can grow in two ways: primary growth and secondary growth.
  • Step 2: Know that primary growth makes plants taller and occurs at the tips of roots and stems.
  • Step 3: Learn that secondary growth makes plants thicker (girth) and occurs in the stems and roots.
  • Step 4: Identify that lateral meristem is the part of the plant responsible for secondary growth.
  • Step 5: Recognize that there are two types of lateral meristem: vascular cambium and cork cambium.
  • Step 6: Understand that vascular cambium helps in forming new vascular tissues (xylem and phloem) for transport.
  • Step 7: Know that cork cambium produces cork cells that protect the plant.
