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 in Group A were grown in cube-shaped containers that were 3 centimeters deep. The plants in Group B were grown in cube-shaped containers that were 10 centimeters deep. The table shows the student's observations

Question

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 in Group A were grown in cube-shaped containers that were 3 centimeters deep. The plants in Group B were grown in cube-shaped containers that were 10 centimeters deep. The table shows the student's observations

Week Plant Group A (Average Height, cm) Plant Group B (Average Height, cm)
1 2 3
2 3 6
3 5 8
4 7 10
5 8 14
6 10 18
What was the effect of root space on plant growth based on the student's investigation? Use the data from the table to support your answer. Explain how you would know whether this effect was likely due to environmental or genetic factors.

Answer 1

The plants in Group B, which had more root space, grew taller on average compared to the plants in Group A. This suggests that root space has a positive effect on plant growth. To determine whether this effect was due to environmental or genetic factors, the experiment would need to be repeated with different plant varieties to see if the results are consistent. If the same results were found with different plant varieties, it would suggest that root space is an environmental factor affecting plant growth.
