Do all organisms have a organ system?

Best Answer

No, because if you have a single celled organism, you don't have enough cells to make a tissue, so you won't have enough tissue to make organs, and you won't have any organs to create an organ system.

If you mean "are all organs part of an organ system":

All organs are a part of a larger organ system, which simply means that the organs and structures in this organ system work together to perform a function. For e.g. the organs and structures of the cardiovascular system (the heart, the blood vessels and the blood itself) all work together to deliver oxygen and nutrients to all parts of the body.

If you mean "do all organisms have organ systems":

No, not all organisms have organ systems. The development of an organ system is dependent on the size of the organism. Small and simple organisms (e.g. algae) are able to get everything they need to survive directly from its environment through diffusion. Larger, more complex organisms (e.g. dog) needs organs that work together in systems in order to deliver its needs for survival (oxygen, water, nutrition) to all the cells in its body.

Your body has 11 different organ systems. Each group of organs has a different complex function, such as movement, breathing, or digestion. In some cases, one organ system works closely with another on a particular task

Do all organisums have an organ system?

No. Organ systems only develop in larger, complex organisms. E.g. amoeba, a single celled organism, is small enough that all its needs can be obtained by the relevant organelles through diffusion. A dog, a large multi-cellular organisms, needs a system to deliver its requirements to the necessary tissues .

How does an organ system turn into a organism?

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.
