ribosomes
Proteins have diverse structures, diverse chemical properties, and flexible shapes.
Plant cells do need proteins to live/survive. They also make proteins.
The right question would be, "Do cells make proteins FROM small structures called amino acids?" The short answer is, yes. If your interested in how look up the Hierarchy of Protein Structures. Specifically: Primary Structure ie. the amino acid sequence Secondary Structure ie repeating folding patterns (which help determine function.) Tertiary Structure ie. many folds and patters create a 3-D shape. For some proteins this is the final structure to a functional protein (such as ribonuclease). Quaternary Structure ie. Most functional proteins are comprised of two or more polypeptides that each adopt a Tertiary Structure (see above) and then assemble with each other. When proteins consist of more than one polypeptide chain, they are said to have Quarternary Structure.
Ribosomes are the organelles that produce proteins.
Proteins are produced in the mitochondria with ribosomes that are produced by the nucleoli in the nucleus of a cell.

Ribosomes
Cells make their proteins during the process of translation. This occurs in the cytoplasm of the cell.
