Solution

Cell organelle : Cell organelles are the internal organs of a cell responsible for carrying out specific jobs to keep the cell alive. In fact, the word organelle is just a big word which means small organ. These organelles are responsible for providing all the needs of the cell. They work to bring in food supplies, get rid of waste, protect the cell, repair the cell, and help it grow or reproduce.

Cell Organelles are much like organs in our body. Each one has a specific job to complete for the cell. And, if one organelle within the cell stops completing its job, then the cell will die.

Lipids : Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells.
Lipids are derived from two main sources, exogenously from food and endogenously made in the liver. Lipids are essential for many body functions such as building cell membranes, brain functioning and to synthesize hormones.
Examples of lipids include fats, oils, waxes, certain vitamins, hormones and most of the non-protein membrane of cells.

Cellulose : Cellulose is a molecule found in the cellular structure of almost all plants. It is made up of carbon, hydrogen, and oxygen, and it is considered to be the most abundant organic (carbon-based) compound in the world. This compound provides strength and structure to a plant's cell walls, and it is the source of dietary fiber.
