How do plants use nitrate ions that are absorbed from the soil.
A
To make fats
B
To make sugars
C
To make proteins
D
To make starch
Explanation: 

Detailed explanation-1: -Plants can absorb nitrate or nitrite from the soil via their root hairs. If nitrate is absorbed, it is first reduced to nitrite ions and then ammonium ions for incorporation into amino acids, nucleic acids, and chlorophyll.

Detailed explanation-2: -Plants can use nitrogen only when it is present in the soil in a soluble form. This soluble nitrogen is absorbed by the roots of the plants and is used by the plants to make proteins.

Detailed explanation-3: -Plants absorb ammonium and nitrate during the assimilation process, after which they are converted into nitrogen-containing organic molecules, such as amino acids and DNA. Animals cannot absorb nitrates directly. They receive their nutrient supplies by consuming plants or plant-consuming animals.
