Answer: cell wall
Explanation: a cell wall is a complex protective structure which gives shape and protection to a plant cell.
Among the functions of a cell wall is maintaining the structural integrity of a cell and providing strength. Because a cell wall has semi-permeable outer layer, it filters molecules that pass in and out of the cell hence, acting as a defense structure against a variety of external factors. It has pores and receptors that regulate various functions of the cell.

Lipids are the long term energy storage molecules that store a large amount of energy in their carbon-hydrogen bonds. Fats and oils are the storage lipids and are derivatives of fatty acids. Fatty acids have long hydrocarbon chains with many high energy carbon-hydrogen bonds. Excess lipids are mostly stored in the body in the form of fat globules in adipose tissues and are used as fuel when required.
Lipids also serve structural roles. Amphipathic phospholipids are the main component of cell membranes. The lipid bilayer of phospholipids makes the basic structure of membranes in which proteins are embedded. Cell walls are mostly composed of complex sugars or sugar derivatives.
