It’s Still Pretty Simple: Kingdom Protista (Protozoan)
Cell Structure
Protozoans do have a nucleus and it’s surrounded by
a nuclear membrane. They are called eukaryotes, which
means “true nucleus.” They also have cell organelles that
help the nucleus perform all the life processes.
Number of Cells
Most Protozoans are single-celled organisms. A few are made up of two or more cells.
Kinds of Movement
Some Protozoans do not move at all, but many of them are able to move. Some protists
use psuedpods, or false feet. The cell in this type of protists is able to change its shape. It is
able to extend some of the cytoplasm to make a fake foot or two. The feet are able to push or
pull the cell along.
Objective
Observe and summarize information about microorganisms.
 Examine and illustrate size, shape, and structure of organisms found in an environment such as pond
water.
Other protists move using tiny, hair-like structures called cilia. The cilia are found on
the outside of the cell. They are able to move very quickly back and forth, moving the protists
along through water or another liquid.
Finally, some protists move using flagella. These are simple, whip-like structures that
propel the protist through its environment.
Nutrition
Some protists are producers and have chloroplasts and chlorophyll. Others are
consumers.
Is it a Protist or Not?
Any organism that has these specific characteristics is a Protista. If it doesn’t have
these characteristics, it’s not a Protista.
1. Guess what? I have found some new organisms. I think they should be classified as either
Moneran or Protist, but I’m not sure. Look at the following characteristics and see if you can
decide which kingdom they should be in.
a. When I look at one of the organisms in the microscope, I notice a tiny nucleus inside
the cell. A membrane surrounds the nucleus.
This organism should be classified as a Moneran Protist
b. When I look at the next organism, I notice it has more than one cell. I don’t see any
tissues or organs, but the group of cells seems to be one organism, not a colony.
This organism should be classified as a Moneran Protist
c. This organism is moving. I notice that it is a single cell, with a flagellum. I cannot tell
if this organism has a nucleus or not.
This organism should be classified as a Moneran Protist Could be either
Objective

 Examine and illustrate size, shape, and structure of organisms found in an environment such as pond

d. This is a simple organism with chloroplasts in its cell. It makes its own food.
