When you look at the water in a lake or
ocean do you ever imagine that there are
microscopic organisms living there?
These organisms are called protists (proetists) and belong to the kingdom Protista
(proe-tis-tuh).

Kingdom Protista is divided into three
groups based on the organism’s
characteristics.

Protists are simple eukaryotic (you-careee-yaw-tick) organisms found in water,
soil or blood.

Protists are also characterized by their
means of nutrition, motility, or movement,
and cellular arrangement.

Protists, like diatoms (die-uh-tomes), are
beneficial in aquatic ecosystems since
they are primary producers and a
component of plankton (playnk-tun).

Protists can be pathogenic (path-oh-jenick) and cause disease in fruits,
vegetables, and animals.

Diatoms (die-uh-tomes) are unicellular
(you-nih-sell-you-ler) examples of protists
that can create colonies shaped like
ribbons or stars.

single-celled and have shells that are
divided into chambers to allow them to
grow.

A slime mold leads a double life. It lives
mostly independently eating fungi (Funjie) and bacteria.
When food is not available or conditions
are poor, individual cells gather and form
a single, large clump-like cell.

bacteria and releasing nutrients back into
the earth for absorption by the roots of
plants.
