They can function in cell to cell signaling and transport.
Ribosomes functions as factories to produce proteins.
Filtration Slits. They allow water, glucose, vitamins, amino acids, small plamsa proteins, ammonia, urea, and ions to pass.

Cells need proteins for their essential functions because proteins are involved in almost every process within a cell. Proteins help with cell structure, communication, transport of molecules, and catalyzing chemical reactions. Without proteins, cells would not be able to perform their necessary functions for survival and growth.
