To analyze the effect of the fertilizer on the growth of the tomato plants, let’s look at the data provided, focusing on the average height of the plants over a week for both containers.
Here is a concise representation of the heights:
- Day 1: Container A: 3.0 cm, Container B: 3.0 cm
- Day 2: Container A: 3.2 cm, Container B: 3.3 cm
- Day 3: Container A: 3.3 cm, Container B: 3.9 cm
- Day 4: Container A: 3.5 cm, Container B: 4.3 cm
- Day 5: Container A: 3.7 cm, Container B: 4.6 cm
- Day 6: Container A: 3.8 cm, Container B: 4.9 cm
- Day 7: Container A: 3.9 cm, Container B: 5.1 cm
To accurately describe the results, we need to look at the overall growth in both containers over the week.
1. Initial height (Day 1):
- Both containers A and B start at 3.0 cm.
2. Final height (Day 7):
- Container A reaches a height of 3.9 cm.
- Container B reaches a height of 5.1 cm.
Now, let’s determine the total growth in both containers:
- Growth in Container A:
- Final height - Initial height
- \(3.9 \, \text{cm} - 3.0 \, \text{cm} = 0.9 \, \text{cm} \)
- Growth in Container B:
- Final height - Initial height
- \(5.1 \, \text{cm} - 3.0 \, \text{cm} = 2.1 \, \text{cm} \)
By comparing these heights, we see that the plants in Container B (with fertilizer) grew more than the plants in Container A (only water). Specifically, the plants in Container B grew by an additional 1.2 cm (\(2.1 \, \text{cm} - 0.9 \, \text{cm} \)) compared to those in Container A.
Best Description of the Results:
The data indicates that the fertilizer had a positive effect on the growth of the tomato plants. The plants in Container B, which received the fertilizer solution, showed significantly greater growth over the week compared to the plants in Container A, which received only water.
