Question

Vascular cambium is more active towards-

• A. Outer side
• B. Inner side
• C. Sometime innerside, some time outside
• D. Equal on both side

Answer 1

The correct option is B Inner side

Cambium comprises the meristematic cells of procambium. Cambial cells have vacuolated protoplast and thin cell wall, they divide periclinally and produce secondary tissues. Cambium is the lateral meristem occurring parallel to the axis. Typically, the cambium is more active on the inner side compared to the outer side. As a result, a large amount of secondary xylem is developed in comparison to the secondary phloem.

So, the correct answer is option B, Inner side.
