A student conducts an experiment using tomato plants. The student plants five young tomato plants in a pot with soil, places the pot in sunlight, and waters the plants each day for nine days. The student records the height of each plant every other day in a table.
After analyzing the data, the student claims that plants are organisms because they grow. Which statement supports the student’s claim?
Responses
The height of each plant is different at the start of the experiment.
The height of each plant is different at the start of the experiment.
The heights of all of the plants at the end of the experiment are almost the same.
The heights of all of the plants at the end of the experiment are almost the same.
The height of each plant is different every other day.
The height of each plant is different every other day.
The heights of all of the plants are the same throughout the experiment.
The heights of all of the plants are the same throughout the experiment.
The statement that supports the student's claim is: "The height of each plant is different every other day." This statement demonstrates that the plants are growing and changing in height over time, which is a characteristic of organisms.
The statement that supports the student's claim is: "The heights of all of the plants at the end of the experiment are almost the same."
To determine which statement supports the student's claim that plants are organisms because they grow, we need to analyze the given information about the height of the tomato plants throughout the experiment.
In the provided responses, here's the breakdown of each statement:
1. The height of each plant is different at the start of the experiment.
- This statement does not directly support the claim that plants are organisms because they grow. It simply states that the initial heights of the plants are different, which is common among living organisms.
2. The heights of all of the plants at the end of the experiment are almost the same.
- This statement also does not support the claim because the end heights being almost the same does not necessarily relate to growth. It could mean that the plants have stopped growing altogether.
3. The height of each plant is different every other day.
- This statement supports the claim that plants are organisms because they grow. If the height of each plant is different every other day, it suggests that the plants are undergoing growth, which is a characteristic of organisms.
4. The heights of all of the plants are the same throughout the experiment.
- This statement contradicts the claim because if the heights of all the plants remain the same throughout the experiment, it implies that there is no growth happening, which goes against the idea of plants being organisms.
Based on the above analysis, the statement that supports the student's claim is: "The height of each plant is different every other day."
