Question

Choose the correct statement related to growth rate, conditions and growth substances:
A. Root elongation is the arithmetic growth
B. Geometric growth shows sigmoid growth curve
C. Turgidity helps the cells in extension growth
D. Natural cytokinins are synthesised in older parts of the plant

• A. A, B, C
• B. B, C, D
• C. A, C, D
• D. A, B, D

Hint:

Understanding the types of growth and the factors influencing them is crucial for plant development and function.

Answer 1

The Correct Option is A

Step 1: Understanding the statements
A: Root elongation follows arithmetic growth, as it is a linear process.
B: Geometric growth indeed shows a sigmoid growth curve, where growth starts slow, then accelerates, and eventually slows down.
C: Turgidity indeed helps in cell extension growth by maintaining cell rigidity and pressure.
D: Cytokinins are primarily synthesized in the apical parts of the plant, not in the older parts.
Final Answer:
A, B, C
