A scientist studies the growth of plants in a laboratory. Which experimental procedure would provide evidence that plants need nitrogen to grow?(1 point)
Two plants are grown in pots of soil with different amounts of nitrogen. The plants have sufficient water and sunlight. The scientist measures plant growth.

That one is correct. Trust me

Correct
Yep. Took the test. He's right
Ah, the wondrous world of plants and their nitrogen needs! Well, it seems like the experimental procedure that would provide evidence that plants need nitrogen to grow would be when two plants are grown in pots of soil with different amounts of nitrogen. They both have sufficient water and sunlight. The scientist then measures the plant growth. So, basically, they're giving these plants a nitrogen buffet and observing how they respond. It's like an all-you-can-eat nitrogen buffet for the plants! Bon appé, little green guys!
The experimental procedure that would provide evidence that plants need nitrogen to grow is: Two plants are grown in pots of soil with different amounts of nitrogen. The plants have sufficient water and sunlight. The scientist measures plant growth.
To understand why this procedure provides evidence for the need of nitrogen for plant growth, let's break it down:
1. Two plants are grown in pots of soil with different amounts of nitrogen: This step involves using two identical plants and placing each of them in separate pots with different amounts of nitrogen. This means that one pot will have a sufficient amount of nitrogen, while the other pot will have a lower or no nitrogen content.
2. The plants have sufficient water and sunlight: It is essential to provide both plants with adequate amounts of water and exposure to sunlight. This ensures that any difference in plant growth can be attributed to the varying nitrogen levels rather than other factors such as water or sunlight availability.
3. The scientist measures plant growth: To determine the effect of nitrogen on plant growth, the scientist measures the growth of both plants. By comparing the growth of the plant with sufficient nitrogen to the other plant, any disparity in growth can be attributed to the presence (or absence) of nitrogen.
In summary, by observing and comparing the growth of two plants with different levels of nitrogen, while keeping other growth factors consistent, the scientist can determine the impact of nitrogen on plant growth.
