Question

In a dicot stem, secondary growth occurs due to the activity of

• A. Apical meristem
• B. Lateral meristem
• C. Cork
• D. Bark

Answer 1

The correct option is B Lateral meristem

Secondary growth refers to the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken. Secondary growth occurs in most seed plants, but monocots usually lack secondary growth.

Apical meristem causes primary growth.

Cork is an impermeable, buoyant material, a prime-subset of bark tissue.

Bark is the outermost layers of stems and roots of woody plants.
