What is the most highly organized cell a tissue a organ or a organism?

Answer 1

If you are talking about a single organism...

Then the Organism would be the whole, and thus the largest.

An Organ System would be next, possibly comprising of multiple individual organs.

Then Organ.

Tissue typically means a portion of an organ.

Cell would be the smallest.

Obviously there are unicellular organisms, in which case that would fall to the bottom of the list.

Answer 2

The most highly organized unit is the organism, which is made up of various organs, tissues, and cells working together in a coordinated manner to perform specific functions and maintain homeostasis. Within the organism, organs are composed of different tissues, which are in turn made up of specialized cells that carry out specific roles to support the overall function of the organ and, ultimately, the organism as a whole.

Answer 3

so obviously not a single celled organism?! its an organ system.

Answer 4

An organism, of course. The organisms contains all these other levels of organization, so it is the most highly organized of the four choices.
