What modification would a plant — especially tree — develop in a world where everything is made of sugar, caramel, cake, syrup, soda, etc.?
Think of something like Willy Wonka's Chocolate Factory, or whole cake island from One Piece, except it doesn’t get moldy or stale or decay in any way.
I was thinking it was due to some advanced preservative chemical in it, but I want to know how different the plant would be if the world doesn't have preservatives and just for some reason this sweet planet never develops fungus or mold, never gets stale, etc.
Would the plant need to have animal-like organs as in the answer what organs or modification needed to have plants that drink liquid blood? Maybe they would need liver and kidney or maybe pancreas or insulin? Or are botanical organs/systems (roots, leaves, etc.) sufficient?
I know there are plants that contains high concentrations of sucrose, like sugarcane, but since this world is literally made of sugar and stuff, would the plant be different or more likely put their excess food in different parts like the root or something?
The majority of the plant itself is a normal plant, but if possible I also want to know what they would be like if they were made of sweet material such as the rest of the world is made of.
I also want the plant to be able to bear fruit and flower, but I guess since everything is made of sugar and sweetness there won't be animals attracted to the flowers, so it probably uses wind more as pollination method.
As I mention, this is real plant that performs photosynthesis, so fungus and such is not part of this. Carnivorous plants are also out of the question.
