Question

Which is the SIMPLEST level of organization in a human being? A) cells B) organs C) tissues Eliminate D) organ systems

Answer 1

The Simplest level of organization in a human being is (A) cells

Explanation:

• It is easier to think about the body's architecture in terms of fundamental levels of organization that rise in complexity, such as (from smallest to largest): cells, tissues, organs, organ systems, and an organism.
• The body's organization is frequently characterized in terms of six distinct stages of increasing complexity. Cells are life's tiniest functioning units.
• The organismal level is the most complicated level of structure, where all eleven organ systems work in the human organism, the entire living person.

Answer 2

Humans, like other living cells, have the same set of organs that work together to perform the functions that keep us alive.

• The body is organized into layers that build on each other. Tissues are made up of cells, tissues are made up of organs, and organs are made up of organ systems.
• At the most basic level of structure, cells are a basic unit of life. Cells can be prokaryotic (outside the nucleus) or eukaryotic (one nucleus). As a result, option A is the right choice.
