What are the levels of Organisation in multicellular organisms?
The body of a multicellular organism, such as a tree or a cat, exhibits organization at several levels: tissues, organs, and organ systems. Similar cells are grouped into tissues, groups of tissues make up organs, and organs with a similar function are grouped into an organ system.
Why are there levels of Organisation in multicellular organisms?
Some living things contain one cell that performs all needed functions. Multicellular organisms are made of many parts that are needed for survival. These parts are divided into levels of organization. Many cells working together form tissue.
What are the levels of organization in order?
An organism is made up of four levels of organization: cells, tissues, organs, and organ systems.
What are the 8 levels of organization from smallest to largest?
