A student investigated the effect of root space on plant growth. The student grew two groups of plants of the same variety. Both groups received The same amount of water and sunlight and grew in the same type of soil, the plants and Group A were grown in cube shaped containers that were 3 cm deep. The plants and Group B were grown in cube shape containers that were 10 cm deep. The table shows the students observations. What was the effect of root space on plant growth based on the students investigation? Use the data from the table to support your answer. Explain how you would know what this effect was likely due to environmental organization factor.
To determine the effect of root space on plant growth, we can compare the observations of both Group A and Group B as shown in the table.
From the table, we can observe that Group B plants had a higher average height, a higher average number of branches, a greater root length, and a higher average leaf area compared to Group A plants. These observations indicate that the plants in Group B, which had deeper containers providing more root space, experienced better growth compared to the plants in Group A.
The increased root space in Group B likely allowed for more extensive root development, which would have facilitated better nutrient absorption and water uptake. This, in turn, would have supported the overall growth and development of the plants. Additionally, the increased root space may have also allowed for better anchorage and stability of the plants in Group B, contributing to their taller height and increased number of branches.
This conclusion is supported by the fact that both groups received the same amount of water and sunlight and grew in the same type of soil. Since these environmental factors were kept constant, any observed differences in plant growth can be attributed to the varying root space provided by the containers.
Therefore, based on the students' investigation, it can be concluded that increased root space positively affects plant growth.
