The cell
Describe unicellular organisms
In unicellular organisms, cells perform all functions on their own, such as, ingestion, digestion, metabolism and waste disposal. Bacteria is an example of a unicellular organism.
Describe multicellular organisms
In multicellular organisms, cells work together and are specialized in one function. They all rely on each other. A human is an example of a multicellular organism.
What are tissues ?
Tissues are a group of cells that have a similar structure and are arranged in a specific way to achieve a function
What are organs ?
Organs are distinct structures made of different types of tissues. The types of tissues in an organ determine its function(s).
What is an organ system ?
