Question

The length of stem increases due to________

• A. Cambial activity
• B. Apical meristem
• C. Lateral meristem
• D. Cork cambium

Answer 1

The correct option is B Apical meristem

• Apical meristem is a meristem at the tip of a plant shoot or root that produces auxin and causes the shoot or root to increase in length.
• Growth that originates in the apical meristem is called primary growth. Due to cambial activity, lateral meristem and cork cambium, the width of a plant will increase.

Therefore, the correct answer is option B.
