Humans require organ system to carry out life processes singled celld organisim do not have orgAN SYSTEM and yey they are able to carry out life processes because?

Answer 1

It's simple really the reason why multi-cell beings need organs in the first place is because they have so many cells. The cells have needs that they cannot obtain alone and must rely on the cells to produce such. For example the Heart pumps the blood which brings oxygen to the cells. Its a much more complex system and therefor makes cells have certain tasks all of which are extremely important and ensures the survival of themselves and the other cells in the body.

Single cell life on the other hand can just absorb what it needs through its surroundings.

Answer 2

Single-celled organisms have simpler structures that allow them to carry out essential life processes directly through their cell membrane. They do not require organ systems because their small size and basic functions enable them to perform all necessary activities independently. This efficiency is a result of their unicellular nature.
