The kingdom that contains organisms with cell walls of chitin and cannot photosynthesize is Fungi.

Here's why:

* Chitin: Chitin is a tough, nitrogen-containing polysaccharide that makes up the cell walls of fungi.

* Lack of Photosynthesis: Fungi are heterotrophs, meaning they cannot produce their own food through photosynthesis. They obtain nutrients by absorbing organic matter from their surroundings.
