It's considerable a classification law in existence world. Thus, simple parts gather in a class and create complex parts. Then these complex parts gather in a class and create next more complex parts, and this process continue continuously till come to existence so complex parts finally.
Electrons, protons and neutrons which are the most simple form of substance, gather in a class and create atoms. Atoms themselves gather in a class and create elements. At next stage, elements gather in a class and create complex molecules. Complex molecules gather in a class and create complex organic molecules. At next stage, complex organic molecules gather in a class and create cell organs (organelles). Also cells gather in a class and create animals and plants.
Here the question is this: Is structural unit of developed animals and plants the cell? Isn't cell a very small unit for creating developed beings.
As getting created for an atom, it gets created from atoms maximum containing tens of electrons and protons. As getting created a simple molecule, it's been used only maximum tens of molecules. But we observe a developed being has been organized from milliards of cell. Can cell be organizing unit of developed beings? It may getting body's systems and tissues between these two class, that's cells gather in a class and organize tissues and then tissues gather in a class and create body's systems and finally these systems gather in a class and create developed animals and plants. In this case, numbers of parts organizing developed animals body and body's systems are the same, and so the problem solves, because there are two other steps, tissues and systems, between cell and whole body. May it be considered tissues and body systems as a step of world's classification systems' steps.
As speaking getting electrons and protons in a class and atoms, our intention is parts which can exist independently in the world themselves. An electron can exist individually without entering into partnership in an atom. It's been said, a simple molecule is been made gathering atoms in a class. These atoms exist individually before gathering in a class. If analyze this simple molecule, can obtain it's organizing atom and use these atoms making other molecules, we use it's one atom in this molecule and other one in other molecule. So atoms taking part in a molecule, don't miss their nature, while have entered into partnership for a molecule, preserve themselves as being atom and after analyzing molecule, they are left over an atom too with their same initial specifications. As gathering some simple molecules and creating a complex organic molecule, simple molecules don't miss their specifications. It's recognizable simple molecules from each other in an organic molecule and it's possible removing one and replacing another instead of it. It's possible analyzing an organic molecule and obtaining initial simple molecules, and these obtained simple molecules may be used in structure of other complex molecules. As gathering organelles in a class and creation a cell, they don't miss their nature. A mitochondrion, settles in a class and organizing a cell, but keeps it's nature as a mitochondrion. A mitochondrion can grow inside a cell, can reproduce and multiply it's numbers, and even it may die before the cell. A grain chloroplast is alike too. If we inject antibiotic into oglena cell, chloroplast inside it, will die, but oglena itself don't die. A nucleus is alike too. It can get divided itself along without getting divided the cell, and multiply it's numbers, as body muscles' cell, or can die before the cell, as body's red cells. i.e., organelles organize the cell together with, but have independent nature for themselves.
So, a total conclusion is this: parts of a class have power of existence in present conditions or had in past conditions.
Let's go back to the subject of animates' body tissues and systems. Have these parts independent existence conditions in the present time? Or had in the past?
If we want to know body systems as components of body of a developed living animate, we must accept that these systems can exist independently from each other in a conditions. Also they must have ability of separation from each other and making rebuild in new composition.
Can this be accepted and may getting evidences for it?
