Plant cells are made of long chains of protein which are made of long chains of amino acids. Each amino acid has an 'r' group which defines it's own special properties. It's the 'r' group attractions to each other that make them clump up and form these long strands of cell wall (fiber) which defines the plant cells. As they are heated, the 'r' group attractions break apart. Therefore denaturing it and forming new molecules.

Hope I answered your question! :D
