Describe the relationship between a ruminant and its microbial symbionts in terms of teamwork

Ruminant animals use a special four-chambered stomach with a unique microbial flora to digest tough cellulose found in the plants in their diets. Most vertebrates cannot make cellulase, the enzyme that breaks down cellulose, but microbes in the rumen produce it for them.

What are the choices?

Both prokaryotic and eukaryotic cells have ribosomes and cell membranes
