What functions do cells perform?

Cells perform a variety of essential functions that are crucial for the overall functioning of an organism. The correct choice highlights that cells are involved in generating and storing energy, removing waste, and creating proteins, which are fundamental processes for life.

Generating and storing energy is vital because cells need energy to carry out their activities, such as growth, maintenance, and repair. This energy is commonly stored in the form of ATP (adenosine triphosphate), which cells can then use for various metabolic processes.

The removal of waste is another critical function of cells. As cells carry out metabolic activities, they produce byproducts that can be harmful if allowed to accumulate. Thus, cells have mechanisms to transport these waste materials out of their structures to maintain a healthy internal environment.

Creating proteins is essential for cells to perform their roles. Proteins are involved in almost every cellular process, from catalyzing biochemical reactions as enzymes to serving as structural components and signals. The process of protein synthesis allows cells to produce the necessary proteins to support their functions and fulfill the organism's needs.

This combination of energy generation, waste removal, and protein synthesis ensures that cells can maintain homeostasis, respond to their environment, and contribute to the overall functions of tissues and organs in multicellular
