Question

Complementary cells are formed from

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
**Primary Concept**: Origin of complementary cells in plants
**Related Topics**: Cork cambium (phellogen), plant cell types, plant tissues
**Prerequisites**: Basic knowledge of plant anatomy and secondary growth
## SOLUTION PATHWAY
**Given Information**:
    - The question asks about the origin of complementary cells.
**Method & Steps**:
    1. **Recall**: Complementary cells are a component of the periderm, which is a protective tissue in plants.
    2. **Recall**: The phellogen (cork cambium) is the meristematic tissue responsible for the formation of the periderm, which includes cork cells and phelloderm cells. Complementary cells are also part of the periderm.
**Result**: The correct answer is Phellogen.
## OPTION ANALYSIS
[A] :x: Vascular cambium produces secondary xylem and phloem, not complementary cells.
[B] ✓: Phellogen (cork cambium) produces the periderm, including complementary cells.
[C] :x: Apical meristems are responsible for primary growth (length) not secondary tissues like periderm.
[D] :x: Intercalary meristems are involved in growth between nodes, not the formation of complementary cells.
## LEARNING AIDS
**Common Mistakes**:
    1. Confusing vascular cambium with phellogen: Remember that vascular cambium forms vascular tissues, while phellogen forms protective tissues.
    2. Not knowing the function of different meristems: Apical meristem adds length, intercalary meristems add length between nodes, and lateral meristems (vascular and cork cambium) adds girth.
**Quick Tips**:
    1. Associate 'phellogen' with 'periderm' and 'protective' to remember its function.
    2. Use mnemonics to remember the function of different meristems.
