where do you find "cell structures and functions" ?
All living organisms have cells. These cells have different structures and perform different functions
The cell is the functional basic unit of life. It was discovered by Robert Hooke and is the functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing, and is often called the building block of life.[1] Some organisms, such as most bacteria, are unicellular (consist of a single cell). Other organisms, such as humans, are multicellular. different organelles of body are made of different type cells ( that is the cells have different structure) and perform different functions http://library.thinkquest.org/12413/structures.html http://www.slideshare.net/joleneg98/cell-structures-and-functions
every cell has its organelles..and they have every function making them different from others..
