Answer;

D) No sugar would be made by the plant.

Explanation; The Calvin cycle is the cycle of chemical reactions performed by plants to FIX carbon from CO2 into three-carbon sugars. The three-carbon sugars may be in turn used to make amino acids, nucleotides, and more complex sugars such as starches. The sugars created in the Calvin cycle are used by plants for long-term energy storage, unlike ATP which is used up quickly after it is created. The main function of the Calvin cycle is to create three-carbon sugars, which is used to build other sugars such as glucose, starch, and cellulose. Therefore; If an herbicide blocked the Calvin cycle before the generation of glyceraldehyde 3-phosphate (G3P), it means no sugar would be nade by the plant.
