Question

Plants can use nitrogen directly from the almost atmosphere ​

Answer 1

Answer:

Earth's atmosphere contains a huge pool of nitrogen gas (N2). But this nitrogen is “unavailable” to plants, because the gaseous form cannot be used directly by plants without undergoing a transformation. To be used by plants, the N2 must be transformed through a process called nitrogen fixation.

Explanation:

But plants do not use nitrogen directly from the air. This is because nitrogen itself is unreactive, and cannot be used by green plants to make protein. Nitrogen gas therefore, needs to be converted into nitrate compound in the soil by nitrogen-fixing bacteria in soil, root nodules or lightning.

Answer 2

Answer: plants cannot use nitrogen directly from the atmosphere. Only the roots of the plants can absorb nitrogen that is present in the atmosphere. In plants, only oxygen and carbon dioxide are absorbed from the atmosphere through stomata by leaves.
