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

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. can u make it shorter?
The effect of root space on plant growth, as observed by the student, was that plants in Group B, which had deeper containers, had significantly greater average heights compared to plants in Group A. This can be confirmed by looking at the data provided in the table.
To determine whether this effect was likely due to environmental or genetic factors, further investigation would be needed. This could involve conducting additional experiments, such as growing plants with varying root space in controlled environmental conditions, or comparing the growth of plants of the same genetic variety in different soil types. By controlling other variables (such as water, sunlight, and soil type) and observing the plant growth, the extent to which root space influences plant growth can be better understood.
