Hy!
Steemit friends!
I am going to describe organelle and cell level.
ORGANELLE LEVEL:
In cellular organization of living organisms the biomolecules that may be micro or macro molecules combine together in a specific manner and form organelles that are sub cellular structures and perform different functions.
e.g
Mitochondria,ribosome etc
CELL LEVEL:
The sub cellular structures/ organelles combine together to form unit of life "cell" The function of cell is accomplished by the function of organelle .The organism may be unicellular or multicellular.
Thanks...
