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 and group a or grown and cube shaped containers that were 3 cm deep Plants in group B were grown in cube shaped containers that were 10 cm deep. The table shows the students observations one a 2 cm one plant B is 3 cm week two plant a is 3 cm two for plant B is 6 cm three is 5 cm B is 8 cm on week three on week four plant a is 7 cm and on plant B for week four it is 10 cm for week five plant a is 8 cm for week five for plant B. It is 14 cm , six is 10 cm and for plant B it is 18 cm on week six so what was the effect of root 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 the effect was likely due to environmental or genetic factors. Explain in 1 to 5 sentences
Based on the data from the table, it is clear that plants in group B, which had more root space, grew taller and faster compared to plants in group A. This suggests that root space has a positive effect on plant growth. To determine if the effect was due to environmental or genetic factors, one could conduct further experiments by changing other variables such as soil composition or sunlight exposure while keeping root space constant. If the difference in growth persists despite these changes, it is more likely that root space is the main factor influencing plant growth.
