Based on the data from the table, it can be observed that the plants in Group B, which had more root space (10 centimeters deep containers), had a greater average height compared to the plants in Group A, which had less root space (3 centimeters deep containers).
For example, at Week 1, Group A had an average height of 2 cm, while Group B had an average height of 3 cm. As the weeks progressed, the difference in average height between the two groups became more pronounced. By Week 6, Group A had an average height of 10 cm, while Group B had an average height of 18 cm.
This indicates that root space has a positive effect on plant growth. The plants in Group B, with more root space, were able to grow taller compared to the plants in Group A with less root space.
To determine whether this effect was likely due to environmental or genetic factors, we would need to conduct further experiments. For example, we can randomly select plants from Group A and transplant them into larger containers with more root space, while randomly selecting plants from Group B and transplanting them into smaller containers with less root space. By doing this, we can see if the plants in Group A show improved growth when given more root space, and if the plants in Group B show decreased growth when given less root space. If the plants exhibit similar growth patterns in the different environments, it would suggest that the effect is likely due to genetic factors. However, if the plants show different growth patterns in the different environments, it would indicate that the effect is more likely due to environmental factors.
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

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.
