The cell walls of plants are made of cellulose. Approximately 33 percent of all plant material is cellulose. Humans cannot digest cellulose, but animals such as cows and horses can digest cellulose for food.
People cannot digest cellulose
Animals such as cows, horses, sheep, goats, and termites have symbiotic bacteria in the intestinal tract that contain the enzymes that allow them to digest cellulose in the GI tract. No vertebrate (animals with an internal skeleton) can digest cellulose directly; all must use the enzyme to break down cellulose.
the appendix digest cellulose, but human appendix does not work.
Grass has cellulose, which humans do not have the bacteria to digest, like cows or horses do. You can eat it, but you can't really digest it for energy. Also, something about not having a working appendix.
None. Humans can't digest cellulose. Bacteria in the large intestine can digest some cellulose, creating gas and vitamin K.
None. Animals that can digest cellulose host special bacteria to digest the cellulose molecules, and humans do not host these.

Actually ruminants cannot digest cellulose, they have symbiotic bacteria in a part of their stomach called a "rumen" digest the cellulose down to sugars and starches that the ruminants can actually digest in another part of their stomach later.
