Organizational Hierarchy of Organisms

Katia drew the following diagram to describe the levels of structural organization of an animal’s body. At the top of the pyramid she put the animal’s body. The level of organization that is least specialized will be at the bottom.  Which of the following should Katia list at the bottom of his diagram?

• organ

• tissue

• cell

• organ system

Living things are organized into different levels of complexity.  The illustration shows how plants and humans are organized.  Which of these is a pattern that exists as the levels of organization move from smallest to largest?

• The organization becomes more complex from A to E.

• The organization of plants is more complicated than that of animals.

• The complexity of the organization decreases as the organism gets larger.

• Level C is always multicellular in plants and unicellular in animals

Living things are organized into different levels of complexity.  The illustration shows how plants and humans are organized. How does organization level B relate to level A?

• All the cells that make up level B have the same function

• The tissues that make up level B are the same in all organs

• Level B can only be found in the organ systems that exchange gases

• Organisms that show the structures of level B can only be unicellular
