Question

The roots of the onion stops to grow once we cut their tips because:

• A. the growth of the plant continues to occur in other parts
• B. the meristematic growth is stopped
• C. the plant continues to grow laterally
• D. none of the above

Answer 1

The correct option is B

the meristematic growth is stopped

The roots of the onion stop to grow once we cut their tips because the meristematic growth is stopped. The growth of plant occurs only in certain specific regions. This is because the dividing tissue, also known as meristematic tissue, is located only at these points. Depending on the region where they are present, meristematic tissues are classified as apical, lateral and intercalary.
