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.

im 12 so not to many huge words

Answer 1

Based on the data, it is clear that the plants in Group B, which had more root space (10 cm deep containers), grew taller than the plants in Group A, which had less root space (3 cm deep containers).

This shows that root space had a positive effect on plant growth in this investigation. As the plants in Group B were able to grow taller and faster compared to the plants in Group A.

To determine whether this effect was likely due to environmental or genetic factors, you could conduct further experiments by switching the plants from Group A and Group B to see if the trend continues. If the plants from Group B were moved to the smaller containers and did not continue to grow as well, it would suggest that the root space itself was the main factor in the difference in growth. Conversely, if the plants from Group A were moved to the larger containers and thrived, it could suggest that there may have been genetic differences between the two groups of plants.

Overall, the effect of root space on plant growth can likely be attributed to environmental factors in this investigation since the only difference between the two groups was the amount of root space they had in their containers.
