The formation of starch in plants involves assembling many G3P molecules, with or without further rearrangements.
Sugar is made during the Calvin cycle, which is the second stage of photosynthesis. In this stage, carbon dioxide is converted into glucose using energy from ATP and NADPH produced in the light-dependent reactions.
The Calvin cycle is the dark reaction in plants, that results in formation of the glucose molecule. The Calvin Cycle synthesizes G3P Basically, Photosynthesis is divided up into the Light reactions and the Calvin Cycle. The "photo" part is the light reaction part, and the "synthesis" is the Calvin Cycle. The Calvin Cycle's whole existence is to produce sugar. It does this with incorporating CO2 to eventually produce G3P, a sugar that can go on to make glucose etc... The Calvin cycle is powered by NADPH and ATP, which come from the light reactions. Of course this is a simplified version, as there are a number of intermediate molecules, but the idea is the same.For more info I would recommend reading Campbell and Reece (6th ed, 2005)
Ah, one very common misconception in biology. Glucose IS NOT made in the Calvin cycle. The Calvin cycle fixes carbon---takes the uber-stable CO2 and turns it into a form of carbon that can later be used to form sugars. The final product of the Calvin cycle that is eventually converted into sugar and cellulose is glyceraldehyde-3-phosphate.
The products of the Calvin cycle are 2 glyceraldehyde-3-phosphate (G3P) molecules, 3 ADP, and 2 NADP+ -By: Isaiah_the_nerd
The products of the Calvin cycle are the three carbon sugar phosphate molecules or the triose phosphates (G3P). The products formed after a single turn of the Calvin cycle are 3 ADP, 2 glyceraldehyde-3-phosphate (G3P) molecules, and 2 NADP+.

Ribulose, C5H10O5 (where the numbers should be subscripts) is a ketopentose.
Calvin cycle
the Calvin cycle of the dark reaction
The Calvin cycle does not require light because it uses ATP and NADPH produced from the light reactions to produce sugar. ATP and NADPH power the reaction to produce sugar from CO2
Carbon dioxide
carbon dioxide
CO2 assimilation and hexose sugar formation
RuBP, PGA, ATP
