If you mean "can it be dissolved" then I have no idea. If you mean "can it be digested" then yes it can. Cellulose, a molecule that forms the cell wall of plant cells, cannot be digested by humans, hence why there's sweetcorn in the toilet after you've eaten it, if you know what I mean. However, the rest of the cell can be digested, just like animal cells. By chewing your food properly you can break the cells in the sweetcorn open, allowing digestive enzymes from your stomach to enter the cells and digest everything, leaving just the cellulose behind.
Salad cannot be dissolved in liquid (so it is insoluble in that context).

There was a story about a mischievous boy who walked in his dining room, saddled up a chair and said to his father, hiya pop, ya ole dust mop. He was amazed he didn't get in trouble. I did the same thing 35 years ago and my dad smiled and said pretty good.
