Question

In plants growth occur by … throughout their life span.
Choose an appropriate option to complete the given NCERT statement

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Plant Growth
 **Related Topics**: Cell Division, Meristematic Tissue
 **Prerequisites**: Basic knowledge of plant biology and growth processes
## SOLUTION PATHWAY
**Given Information**:
  *  The question asks about the primary mechanism of plant growth throughout their lifespan.
**Method & Steps**:
 1. **Recall**: Plant growth involves an increase in cell number and size.
    Reasoning: This is a fundamental aspect of plant development.
 2. **Identify**: Cell multiplication (mitosis) is the process that increases cell number.
    Key Point: This process occurs continuously in meristematic tissues.
 3. **Conclude**: Therefore, growth in plants occurs by cell multiplication throughout their lifespan.
    Result: Cell multiplication is the correct answer.
## OPTION ANALYSIS
[A] :x: Cell dedifferentiation is the process where a specialized cell reverts to a simpler state. It's not the primary growth mechanism. 
[B] :x: Cell differentiation is the process by which cells become specialized. It is involved in growth, but it's not the primary mechanism driving it.
[C] ✓: Cell multiplication through mitosis is the main driver of plant growth throughout their lifespan.
[D] :x: There is a correct option, so 'None of these' is incorrect.
## LEARNING AIDS
 **Common Mistakes**:
 1. Confusing differentiation with multiplication: Differentiation is specialization, not growth in number.
 2. Not recalling basic plant growth: Growth fundamentally relies on cell division.
 **Quick Tips**:
 1. Remember that meristematic tissues are responsible for continuous cell division.
 2. Connect growth with increase in cell number, which is achieved by multiplication.
