1.1.1.3.1. many different kinds of cells in groups do the main function for the body
1.1.1.3.2. example
1.1.1.4. similar cells together form a tissue
1.1.2. tissue
1.1.2.1. it is a group of similar cells combined to do a specific function
1.1.2.2. only multicellular organisms have tissues
1.1.2.2.1. example
1.1.2.3. many tissues together doing a specific function form organs
