Eli5 if plants peoduce glucose by photosynthesis, why it’s taste not felt in green vegetables?

Plants use glucose to build cellulose and starch, which are long strings or webs of glucose. Cellulose is what makes up the cell wall, which gives plants strength and rigidity, while starch stores energy.
Even though both these molecules are made of glucose neither of them taste sweet to you because your tongue’s glucose-detecting taste buds are looking for free glucose, and the glucose bound up in cellulose and starch are stuck together very tightly. Your saliva contains enzymes that break down starch, but you have to chew on something for a long time before you start to notice the free glucose.
