II. Abstract

This experiment aims to examine how varying light intensities affect the growth rates of a specific plant species, using controlled environmental conditions and consistent measurement techniques.

III. Introduction

The purpose of this experiment is to study the correlation between light intensity and plant growth, contributing valuable insights to the field of botany and agricultural sciences.

IV. Materials and Methods

A. Materials

• Plant species: Arabidopsis thaliana

• Light sources of varying intensities

• Growth chambers

• Soil and fertilizers specific to Arabidopsis thaliana

• Rulers and measuring tools

• Data recording sheets

B. Methods

1. Plant seeds in uniform pots with consistent soil composition.

2. Distribute plants evenly in growth chambers with different light intensities: 100%, 75%, 50%, 25%.

3. Water plants uniformly and maintain consistent temperature and humidity across chambers.

4. Measure plant height weekly for 12 weeks using a ruler.

5. Record data in the data log sheet for analysis.

V. Results

Week	100% Light Intensity (cm)	75% Light Intensity (cm)	50% Light Intensity (cm)	25% Light Intensity (cm)
1	2.1	1.8	1.6	1.2
2	3.5	3.0	2.7	2.0

VI. Discussion

The data suggests a clear positive relationship between light intensity and plant growth rates. Plants exposed to higher light intensities demonstrated faster and more consistent growth compared to those exposed to lower light intensities.

VII. Conclusion

This experiment confirms that light intensity significantly impacts plant growth, contributing to the broader understanding of optimal agricultural practices.
