Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In order to make proteins, plants need to absorb
A
Magnesium Ions
B
Nitrate Ions
C
Sucrose
D
Carbon Dioxide
Explanation: 

Detailed explanation-1: -All plants absorb nitrogen as NO3 (nitrate ion) from the soil. These are then converted to ammonium ions to combine into amino acids and eventually convert into proteins.

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: -Nitrate serves plants as a nutrient and is an important growth factor. It is absorbed from the soil through the roots and helps build organic compounds such as proteins and nucleic acids. Nitrite (NO2-) is an intermediate product in the conversion of nitrate and is formed with the help of microorganisms and enzymes.

Detailed explanation-4: -Ammonia is converted to nitrates by nitrifying bacteria in the soil. Plants absorb nitrates from the soil and use these to build up proteins. The plant may be eaten by an animal, and its biomass used to produce animal protein.
