Cellulose is found throughout the cell wall of plant cells so cellulose make cells walls Ridgid which indicates that Cellulose is a

Cellulose makes cell walls rigid, so that would indicate that cellulose is a carbohydrate.

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
