Detailed explanation-1: -Answer: Option A Solution: The plant cells absorb nitrates from the soil and convert them into ammonia which ultimately reduced to ammonium ions (NH4+). These ammonium ions are then combined with organic compounds to form amino acids such as glutamine i.e., free nitrogen.
Detailed explanation-2: -Plants take up nitrate from the soil via the transporter proteins present in the root cell membrane. There are other nitrate transporters that are involved in moving nitrate within plants to different tissues as needed.
Detailed explanation-3: -Answer and Explanation: Plants absorb dissolved nitrates from soil and convert them into ammonia. This process is referred to as nitrogen fixation.
Detailed explanation-4: -Nitrates and other minerals are taken into a plant via specially adapted root cells called root hair cells.
