Which of the following can be measured by auxanometer?
Option A- Growth in length: Auxanometer is an instrument which is used to measure the growth rate of a plant in terms of length with the help of an arc indicator. Sensitive auxanometer also records growth of even a few micrometers.
How will you obtain plant growth by auxanometer?
Step 1: Take ordinary scale. Step 2: Measure ground stem up to the growing point of the plant. Step 3: Use Indian ink and mark at regular intervals to measure the length of root, stem, and girth of the trunk.
What is the difference between crescograph and auxanometer?
A crescograph is a device that is used to measure the rate of growth in plants. The clockwise gears are used to measure the growth that is influenced by various conditions. The plate contains uniform marks. An auxanometer, also known as an arc-indicator, is a device that is used to measure the growth of plants.
What is the use of arc indicator?
An auxanometer is an apparatus for measuring increase of growth in plants. In case of an arc-auxanometer, there is a wire fixed with the plant apex on one end and a dead-weight on the other. It passes over a pulley which has a pointer attached to it.
What is the function of auxin?
What are the major functions? Answer: Auxin promotes cell growth and elongation of the plant. In the elongation process, auxin alters the plant wall plasticity making it easier for the plant to grow upwards. Auxin also influences rooting formations.
How does an Auxanometer work?
An auxanometer (Gr. auxain, “to grow” + metron, “measure”) is an apparatus used to measure the increase or rate of growth of plants. The the height of the plant increases, the pulley will rotate, and the pointer moves on a circular scale to directly give the magnitude of the plant’s growth.
How is plant growth measured?
Plant growth rate can be measured as the relative increase in leaf area over time, by substituting total plant leaf area for total biomass in the conventional RGR equation.
What did Jagadish Chandra Bose discover?

What new facts does crescograph reveal?
Bose used his invention to introduce the world of plants to the humans. His invention – the Crescograph – showed how plants move. The Bose Crescograph has a series of gears and a smoked glass plate that record the movement of a plant’s tip under a magnetic scale of 1/10000.
What is an Auxanometer or indicator used to measure?
An auxanometer (Gr. auxain= “to grow” + metron= “measure”) is an apparatus for measuring increase of growth in plants.
