Question

Accelerated pace of growth is observed in plants during __________.

• A. cell division
• B. cell elongation
• C. cell maturation
• D. cell differentiation

Hint:

Think of the three phases of growth at a root or shoot tip and which one adds the most size.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
Growth in plants passes through three phases: cell division, cell elongation and cell maturation.

Step 2: Compare the phases
In cell division, new cells are small and add little size.
In cell elongation, cells absorb water, form large vacuoles and add new wall, so their size increases rapidly.
In maturation, growth slows and cells differentiate.

Step 3: Conclusion
The fastest growth is seen in the elongation phase.

Final Answer:
Accelerated growth occurs during cell elongation. \[ \boxed{\text{(B) }\text{cell elongation}} \]
