β In `color{violet}("unicellular organisms")` , all functions like digestion, respiration and reproduction are performed by a `color{brown}("single cell.")`
β In the complex body of `color{violet}("multicellular animals")` the same basic functions are carried out by `color{violet}("different groups of cells")` in a well `color{violet}("organised manner.")`
β The body of a `color{violet}("simple organism")` like `color{violet}("ππΊπ₯π³π’")` is made of different types of cells and the number of cells in each type can be in `color{violet}("thousands.")`
β The human body is `color{violet}("composed of billions")` of cells to perform various functions.
β In `color{violet}("multicellular animals")`, a group of similar cells along with `color{violet}("intercellular substances")` perform a specific function. Such an `color{violet}("organization")` is called `color{brown}("tissue.")`
β Interestingly, all `color{violet}("complex animals")` consist of only `color{brown}("four basic types")` of tissues.
β These tissues are organised in specific proportion and pattern to form an `color{violet}("organ")` like `color{violet}("stomach, lung, heart and kidney.")`
β When two or more `color{violet}("organs")` perform a common function by their `color{violet}("physical and/or chemical ")` interaction, they together form `color{brown}("organ system")`, e.g., digestive system, respiratory system, etc.
β `color{violet}("Cells, tissues, organs and organ")` systems split up the work in a way that `color{violet}("exhibits division")` of labour and contribute to the survival of the body as a whole.
