| Levels of Organization In unicellular (single-celled)
organisms, the single cell performs all life functions. It functions independently.
However, multicellular (many celled) organisms have various levels of organization within
them. Individual cells may perform specific functions (causing a division of labor) and
work together for the good of the entire organism. The cells become dependent on one
another. Explore Cells, Tissues, Organs, Organ Systems, and Organisms. |

| Colors, Colors? Here is
your job: name the colors of the following words. Do NOT read the words...rather, say the
color of the words. For example, for the word BLUE, you should
say "RED". Say the colors as fast as you can. It is not as easy as you might
think! |
