Question

In plants, the conversion of permanent tissues like parenchyma to meristematic tissue like interfascicular cambium is an example of:

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Dedifferentiation in plant tissues
 **Related Topics**: Plant development, cell differentiation, meristematic tissues, permanent tissues
 **Prerequisites**: Understanding of plant tissue types and their characteristics.
## SOLUTION PATHWAY
**Given Information**:
  Conversion of permanent tissue (parenchyma) to meristematic tissue (interfascicular cambium).
  Parenchyma cells are differentiated and have specific functions.
  Interfascicular cambium is a meristematic tissue capable of cell division.
**Method & Steps**:
 1. Analyze the transformation: The permanent parenchyma tissue loses its specialized characteristics and becomes meristematic.
  Reasoning: This involves a change from a differentiated, non-dividing state to a less differentiated, dividing state.
  Formula/Rule: N/A
 2. Identify the process: The process of a differentiated cell reverting to a less specialized state is called dedifferentiation.
  Working: The parenchyma cells essentially 'reset' their developmental program.
  Key Point: This process is critical for plant growth and development.
 3. Confirm the answer: Dedifferentiation accurately describes the conversion of permanent to meristematic tissue.
  Result: Dedifferentiation
  Verification: The described transformation aligns perfectly with the definition of dedifferentiation.
 ## OPTION ANALYSIS
A :x: Redifferentiation is the process of a dedifferentiated cell becoming specialized again, not the initial transition.
B :x: Differentiation is the process of a cell becoming specialized, the opposite of what is happening here.
C ✓: Dedifferentiation accurately describes the change from a permanent, differentiated tissue to a meristematic, less specialized tissue.
D :x: Senescence is programmed cell death, not a reversal of differentiation.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing dedifferentiation with differentiation or senescence.
  2.Not understanding the functional change from permanent to meristematic tissue.
 **Quick Tips**:
  1.Think of dedifferentiation as a 'rejuvenation' of cells, regaining their developmental potential.
  2.Remember the role of dedifferentiation in secondary growth and wound healing in plants.
