A student investigated the effect of root space on plant growth, the student route to groups of plants of the same variety, both groups receive the same amount of water and sunlight, and grew in the same type of soil the planting group, a grown in cube shaped containers that were 3 cm deep. The plants in group B were grown in cube shaped containers that were 10 cm deep. The table shows the students observations Plan a on week one was 2 inches Plan B on week one was 3 inches on week two plant a was 3 inches and plant B on week two was 6 inches on week three plant a was 5 inches and Plan B was 8 inches for plant a was 7 inches and plant B was 10 inches on week five plant a was 8 inches and plant B was 14 inches and on week six plant a was 10 inches and plant B was 18 inches What was the effect of roots space on plant growth based on the students investigation use the data from the table to support your answer explain how you would know whether this affect was likely due to environmental or genetic factors
Based on the data from the table, it is clear that the plants in group B, which had more root space (10 cm deep containers), showed significantly greater growth compared to the plants in group A, which had less root space (3 cm deep containers). This demonstrates that root space has a positive effect on plant growth.
To determine whether this effect was likely due to environmental or genetic factors, additional factors would need to be considered. One way to distinguish between environmental and genetic factors would be to conduct the experiment with different plant varieties to see if the same pattern holds. If different plant varieties showed similar results, it would suggest that root space has a consistent environmental effect on plant growth. On the other hand, if different plant varieties showed varying results, it would indicate that genetic factors play a role in how plants respond to root space.
In this case, since the experiment involved plants of the same variety, it is likely that the observed effect of root space on plant growth is primarily due to environmental factors, specifically the availability of space for root growth. This conclusion is supported by the consistent and significant difference in growth between the two groups throughout the experiment.
