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.

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. %0D%0A%0D%0A(2 points)

Based on the data from the table, it is clear that the plants in Group B, which had larger root space (10 cm deep containers), grew taller on average compared to the plants in Group A, which had smaller root space (3 cm deep containers). This indicates that root space has a positive effect on plant growth.

To determine whether this effect was likely due to environmental or genetic factors, one could conduct further experiments. For example, one could repeat the experiment with different varieties of plants to see if the same pattern emerges. If the same pattern is observed with different plant varieties, it is more likely that the effect is due to environmental factors, such as root space. However, if different plant varieties show different responses to root space, it may suggest that genetic factors play a role in plant growth as well.
