• an atom in the lung

• lung tissue

• the lungs

• the respiratory system

Which of these statements describes an organ system?

An orange is an excellent example of multiple layers or organization inside living things.  You can easily pull apart an orange into different layers. The outside orange layer is called the epicarp and produces oils and waxes.  Inside, the white mesocarp layer protects and nourishes the individual segments. Each segment contains a seed. The segments of the orange are made of many hundreds of juice sacs.  These juice sacs contain sugar and water. And, interestingly enough, each juice sac is one large cell. If each juice sac is a cell, then what is the segment?

• oganelle

• tissue

• organ

• organ system

The sizes of various biological structures are shown in this diagram.  Some can be seen with a light microscope.  Others are so small that other technology is required to visualize them. What would be even smaller than the smallest item in this diagram?

• atom

• cell nucleus

• fungus cell

• piece of DNA

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
