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

The student's investigation showed that the amount of root space really affects how tall plants can grow! In the results, Group A's plants (in the shallow containers) only grew to an average height of 10 cm by week 6, while Group B's plants (in the deep containers) grew much taller, reaching 18 cm!

This shows that plants need enough space for their roots to grow and take in nutrients. Since both groups got the same water, sunlight, and soil, the difference in growth was likely because Group B had more root space.

To find out if the growth difference was due to the environment or the plants' genes, we could try growing another group of the same plants in even deeper containers or test plants from different varieties. If the ones with deeper containers keep growing better, then we know the root space is the key factor!

The student found that plants grow taller when they have more root space! Group A's plants (in shallow pots) were only 10 cm tall after 6 weeks, while Group B's plants (in deep pots) grew to 18 cm!

This shows that roots need enough space to help the plants grow. To see if the difference is because of the roots or the plants’ genes, we could try different pots or other types of plants. If the deep pots always do better, then it’s all about the root space!
