The digestive system functions includes the chemical breakdown of food, mechanical breakdown of food, absorption of food molecules and elimination of waste products.
The digestive tract can be compare to a tube with two openings - mouth and anus. The process of digestion starts from the mouth ( ingestion of food) through the oesophagus down to the stomach (where the food is mixed with digestive juices) then to the small intestine (this is where most of the digestion process takes place) then to the large intestine and finally to the anus where undigested wastes are eliminated

Explanation:
All bacteria contain peptidoglycan in the their cell wall; the major component of peptidoglycan is the N-acetylmuramic acid. The peptidoglycan in bacteria helps to protect the bacteria plasma membrane and cell as a whole from environmental stress as well as maintaining its cell morphology.
In this case, the unicellular organism that was discovered is most likely an archaea. Archaea are organisms that have a semi rigid cell wall with the absence of peptidoglycan.
