How does an organ system turn into a organism?

Answer 1

Organisms are the product of evolution. Organisms did not evolve from organ systems, rather, organisms have evolved organ systems to accomplish various specific biological functions.

However, if we go back farther, to the evolution of the cell, we find that there are organelles, the mitochondria, which have their own genetics, and which almost certainly evolved originally as independent organisms before entering into a symbiotic relationship with cells. It is speculated that perhaps all the organelles of a cell evolved separately. That is the closest we can come, to an organ system that turns into an organism, although it is really an organelle system.

Answer 2

Your question has facts a bit confused. You must understand that an organism -- even a one-celled organism-- is the sum of all of its parts.

So in order of importance it is:

1. the cell -- this is the basis of all organisms
2. many specialized cells
3. many specialized cells that make up tissue
4. specialized tissues that make up an organ
5. organs with similar tissues and functions that make up an organ system
6. many organ systems working together in one organism

But no... an organ system does not "turn into" an organism.

Answer 3

An organism is made up of organ systems working together. Organ systems are groups of organs that work together to perform specific functions within the body. When organ systems collaborate and interact with each other, they collectively form a functioning organism.
