LG 2.1 Trends and Various Strategies Used by Organisms to Process Food Flashcards
There are 4 main stages of food processing namely:
Ingestion, Digestion, Absorption, Elimination
It is the act of eating
Ingestion
This phase comes after ingestion
Digestion
There are 2 types of digestion called:
Mechanical and Chemical Digestion
It is the physical process of breaking or tearing down food.
Mechanical Digestion
It is the chemical process of tearing down food into small particles.
Chemical Digestion
It occurs when digestion is finished; food molecules are broken down and are now absorbed by cells.
Absorption
Waste products of digestion are removed from the body.
Elimination
It is the simplest digestive compartment; Contains food matter to be digested.
Food Vacuoles
When cell takes solid food, it is called ___.
Phagocytosis
It is when a cell takes liquid.
Pinocytosis
It fuses w/ food vacuole, to start digesting food particles.
Lysosome
It is the breaking down of food inside food vacuoles
Intracellular Digestion
The process of breaking down food compartments.
Extracellular Digestion
It is a digestive compartment where food enters and waste exits.
Gastrovascular Activity
