Auxanometer is meant for measuring -a)Respiratory activityb)Photosynthetic activityc)Growth activityd)Osmotic pressureCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Auxanometer is a simple instrument to measure growth of a plant. Most common type of auxanometer is arc auxanometer, which measures growth as the increase in length of axis. This increase can be caused due to increase in mass of protoplasm (cell division) or simply by absorption of water (increase in length or surface of existing cells).

Auxanometer is a simple instrument to measure growth of a plant. Most common type of auxanometer is arc auxanometer, which measures growth as the increase in length of axis. This increase can be caused due to increase in mass of protoplasm (cell division) or simply by absorption of water (increase in length or surface of existing cells).

Answer

The auxanometer is a scientific instrument used for measuring the growth activity of plants. It is designed to measure the rate at which a plant's stem elongates or increases in length. This measurement provides insights into the plant's overall growth and development.

The auxanometer works on the principle of the auxin hormone, which is responsible for regulating plant growth. Auxins are produced in the apical meristem, which is the growing tip of the plant. These hormones promote cell elongation and expansion, leading to an increase in stem length.

The auxanometer consists of a metal rod or wire that is attached to the plant stem. As the stem grows, it pushes against the metal rod, causing it to move or bend. The movement of the rod is then measured using a scale, which provides a quantitative measurement of the plant's growth rate.

By regularly measuring the growth rate using an auxanometer, researchers and scientists can study the effects of various factors on plant growth. This includes the impact of environmental conditions such as light, temperature, and humidity, as well as the influence of hormones and other growth regulators.

The auxanometer is particularly useful in studying tropisms, which are growth responses of plants to external stimuli. For example, it can be used to measure the rate of stem elongation in response to light (phototropism) or gravity (gravitropism). These measurements help in understanding how plants sense and respond to their environment.

Furthermore, the auxanometer can also be used to compare the growth rates of different plant species or different parts of the same plant. This allows researchers to investigate variations in growth patterns and identify factors that contribute to differences in plant growth.

In conclusion, the auxanometer is a valuable tool for measuring the growth activity of plants. It provides quantitative data on stem elongation, allowing researchers to study the effects of various factors on plant growth and development.

Answer

In case of an arc-auxanometer (see picture), there is a wire fixed with the plant apex on one end and a dead-weight on the other. ... Sensitive auxanometersallow measurement ofgrowth as small as a micrometer, which allowsmeasurement of growth in response to short-term changes in atmospheric composition.

Answer

Auxometer is related to measuring the growth in the plants.
