A scientist studies the growth of plants in a laboratory. Which experimental procedure would provide evidence that plants need nitrogen to grow?(1 point)
Responses
Identical plants are placed in two airtight containers with sufficient exposure to sunlight. One container has nitrogen gas, and the other has room air. The scientist measures plant growth.

Seeds are planted in two terrariums. Both terrariums are given adequate water and exposure to sunlight. A plant grows in one terrarium. The scientist measures the nitrogen content of the air.

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.

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.
This setup allows for a direct comparison of how varying nitrogen levels affect plant growth, providing clear evidence of the importance of nitrogen for plant development.
