Question

For a critical study of secondary growth in plants which one of the following pairs is suitable

• A. Wheat and maiden hair fern
• B. Sugarcane and sunflower
• C. Teak and pine
• D. Deodar and fern

Answer 1

The correct option is C Teak and pine

• Secondary growth is the growth that results from active cell division in the cambia or lateral meristems that causes the stems and roots to thicken or grow in width. Secondary growth occurs in gymnosperms and dicots only.
• Teak and pine are most suitable for the study of critical secondary growth because, in secondary growth, secondary tissues are formed from lateral meristem which is well developed in both teak and pine.
