1. The gymnosperm plant known for its ability to fix nitrogen is the genus **Gymnosperm**. Specifically, certain species of **cycads**, such as those in the genus **Cycas**, contain symbiotic cyanobacteria in their roots that can fix atmospheric nitrogen.
2. Yes, during the process of nitrogen fixation, **hydrogen gas (H₂)** is also evolved as a byproduct in the reaction.
3. A total of **16 ATP molecules** are typically required to reduce a single molecule of nitrogen (N₂) to ammonia (NH₃) via the nitrogenase enzyme complex.
4. The major source of electrons for the reduction of nitrogen is derived from **ferredoxin**, which is a small protein that transfers electrons within cells. In the nitrogen fixation process, electrons from reduced ferredoxin are used in the nitrogenase reaction to convert nitrogen gas into ammonia.
