Explanation:
The process that is responsible for the production of the glucose that contributes the carbon that is essential for the formation of amino acids in plants is: photosynthesis.
<h3>What is Photosynthesis?</h3>
Photosynthesis can be described as the process in plants where sunlight, water, and carbon dioxide to synthesize or produce energy in the form of glucose and gives off oxygen as a by-product. Chlorophyll in plants is enables this process also.
For example, green plants which are called photoautotrophs synthesize glucose from carbon dioxide, light energy, and water.
There are two processes that contribute to the formation of amino acids in plants. They are:
Nitrate absorption: this produces the nitrogen needed in forming amino acids in plants.
Photosynthesis: this produces the carbon from glucose which is essential in the formation of amino acids.
In conclusion, the process that is responsible for the production of the glucose that contributes the carbon that is essential for the formation of amino acids in plants is: photosynthesis.
