Question

Auxanometer is meant for measuring

• A. respiratory activity
• B. photosynthetic activity
• C. growth activity
• D. osmotic pressure

Answer 1

The correct option is C growth activity

Auxanometer is an instrument used to measure the increase in growth in plants. The apparatus is set up in such a way that an initial point is marked on the plant, which is known as the reference point. A pointer is focussed onto the reference point and left for some time. The displacement of the reference point from its original position to a new position is measured and calculations are done to measure absolute and relative growth.
