Answer:
The cell wall
Explanation:
The cell wall exists to protect the cell, maintain its shape and regulate water uptake. The cell wall is much thicker than the cell membrane, providing an extra layer of protection. In plants, the cell wall is made of fibres of the polysaccharide cellulose, which is a structural carbohydrate.
This gives organisms such as plants much more structure - e.g. they can stand upright without the need for bones. However, they lack the same flexibility that animal cells have.
The energy that you put into making the machine do work is a product of force and displacement.
If you have to go further with your input force, than the object is moved, then your advantage is increased.
