Auxanometer is used to measure plant organ

Options

A. Growth in length
B. Growth in breadth
C. Pest population
D. Both A and B.

Answer

**Step-by-Step Solution:**

1. **Understanding the Auxanometer**: An auxanometer is an instrument used to measure the growth of plant organs, such as stems or leaves. It quantifies the increase in length or other dimensions of the plant over time.

2. **Function of Auxanometer**: The auxanometer operates by measuring the elongation of plant parts. It typically consists of a scale and a mechanism that can detect and record the changes in length as the plant grows.

3. **Application**: Auxanometers are particularly useful in experiments where the growth rates of different plant species or the effects of various environmental conditions on growth are being studied.

4. **Types of Auxanometers**: There are various types of auxanometers, including simple mechanical devices and more sophisticated electronic versions that can provide continuous readings and data logging.

5. **Importance in Research**: By using an auxanometer, researchers can gather quantitative data on plant growth, which can be vital for studies in botany, agriculture, and ecology.

**Final Answer**: An auxanometer is used to measure the growth of plant organs, specifically their elongation over time.
