[Biology SPM] Exam Pointers IV

Source: Maths & Science Guide

Describe the process of digestion. [ 2 marks ]

Correct Answers
A process in which complex organic food is broken down through physical and chemical processes into simple soluble molecules that can be easily absorbed by the cells.

Include "physical processes" (involving mastication and churning processes) and "chemical processes" ( involving the action of enzymes) in your complete description of the process. Note that food should be referred to as "complex organic food", and that it is broken down into "simple soluble molecules".
