Question

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

Answer 1

Based on the student's investigation, it is clear that having more root space (as shown in Group B with 10 cm deep containers) had a positive effect on plant growth compared to having less root space (as shown in Group A with 3 cm deep containers). This can be seen from the average height of the plants in each group at different weeks:

- In Week 1, both groups had similar average heights of 2 cm and 3 cm for Group A and B, respectively.
- However, as the weeks progressed, the plants in Group B consistently outgrew the plants in Group A. By Week 6, the plants in Group B had an average height of 18 cm, while the plants in Group A only reached an average height of 10 cm.

This growth pattern suggests that having more root space allowed the plants in Group B to develop larger root systems, which in turn supported greater overall growth compared to the plants in Group A with limited root space.

To determine whether this effect was likely due to environmental or genetic factors, further investigations can be conducted. These could include repeating the experiment with different plant varieties to see if the same growth pattern occurs, or altering environmental conditions (such as water and sunlight) to see if they have different effects on plant growth in containers with varying root space. By conducting these additional experiments, the student can determine if the observed effect of root space on plant growth is consistent across different plant varieties and environmental conditions, helping to tease apart the influence of genetics and environment on plant growth.

Answer 3

Having more root space (as shown in Group B with 10 cm deep containers) helped the plants grow taller compared to having less root space (Group A with 3 cm deep containers). This is clear from the average heights of the plants in each group at different weeks. In Week 1, both groups had similar heights of 2 cm and 3 cm, but by Week 6, Group B plants were 18 cm tall while Group A plants were only 10 cm tall.

To find out if this growth was due to environment or genes, we can do more experiments. We could try different plant types to see if the pattern holds, or change how much water and sunlight the plants get. By doing these tests, we can figure out if root space really does make plants grow better, and if it's genes or the environment that make the difference.
