Different cells are different in structure because of their different functions (e.g. plant cells have cell walls because they don't have bones). Also, cells have different functions because they work together with other cells to create a working system (e.g. the human body)
Because the leaf structure do not have the ability to store the starch molecules
Organ
a structure composed of a number of tissues that work together to perform a specific task basikly
Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.
a structure in the cytoplasm organelles; perform various cellular functions
Organelles
their functions
Cellular respiration is one of the processes that cells perform. Organisms do not perform this process. Instead they perform respiration. Cells use cellular respiration to obtain one of the three sources needed for them to live- oxygen. Without this process, cells would not be able to perform other functions.
Because it is a principal component of all cells.
It regenerates itself

They perform cellular respiration but not photosynthesis.

sponges have cellular level organisation meaning that their cells are specialized so that different cells perform different functions
Function describes what cells do; in a multi-cellular organism the function is why the cell exists. And the structure makes it possible for a cell to perform its function.
