1
The Kingdom Protista contains four phyla of
heterotrophic animal like one celled organisms.
They are separated based on their means of
locomotion. The phyla are Ciliaphora,Zoomastigina,
Sarcodina and Sporozoa. Protists are all
eukaryotes
The phylum Ciliaphora contains organisms which
are propelled by cilia. Cilia are much larger
then the flagella of bacteria. Cilia are found
on all parts of the organism. Cilia help sweep
food into the gut of the paramecium. Humans have
cilia in there air passages and in the females
uterus.
A well known genus is the paramecium. Paramecium
reproduce asexually by mitosis and sexually by
conjugation. They ingest food through a gullet
and digest it in food vacuoles. They expel
solid waste through an anal pore and liquid waste
plus excess water through a contractile
vacuole.When threatened they produce sharp spikes
called trichocysts. Paramecium have a
macronucleus which controls life functions and a
micronucleus which is involved in sex.
2
The Phylum Zoomastigina by means of flagella,
which are identical to cilia in structure only
they are longer. Because they have flagella they
are known as flagellates.
Many Zoomastiginans are parasites. Giardia
infects the digestive tracts of humans after they
have drank polluted water. The primary symptoms
include diarrhea, abdominal cramps, headaches,
nausea, vomiting, and low-grade fever, which can
lead to weight loss and dehydration. Another
parasite causes African Sleeping sickness which
is injected by the bite of a Tse Tse fly. These
parasites are not bacterial therefore they do not
respond to antibiotics like penicillin.
3
Members of the Phylum Sporozoa are non-motile.
All of these are parasitic. They have a variety
of different hosts which include worms, fish,
birds and humans. All of these organisms
reproduce by spores.
A typical Sporozoan is Plasmodium which causes
the disease malaria. Malaria is carried by the
Anopheles mosquito. Chloroquinine is an
affective drug against some forms of malaria, but
still the best way to control bacteria is by
eliminating the breeding grounds of the mosquito.
4
Members of the phylum Sarcodina move like bags of
jelly. They extend their cell membrane and form
structures called pseudopods, which means false
foot.
One major family of the Sarcodina is the ameba.
Amebas move by means of thick pseudopods and
there movement is referred to as ameboid
movement.
Amebas surround there food with their pseudopods
and engulf it. Amebas reproduce by means of
binary fission.
Other members of this phylum include the
heliozoans, radiolarians, and foraminifers.
These organisms produce shells of glass or of
calcium carbonate.
5
Plantlike protists are single celled, colonial,
and primitively multicellular. They are
autotrophic and many contain chlorophyll and
chloroplasts.
One phylum is Euglenophyta and they are closely
related to the Zoomastigina. The only difference
seems to be the chloroplasts.
One genus is the Euglena . It has two flagella.
It has a red eyespot which detects light. It can
swim and also crawl by euglenoid movement. The
Euglena can live as a phototrophic autotroph or
as a heterotroph. They are also known as
saprophytes because they eat decaying material.
6
Members of the phylum Pyrrophyta are known as
fire algae. One group of these organisms is
known as dinoflagellates becuses they swim with
two flagella.
An interesting feature of these organisms is they
are luminescent, which means they glow in the
dark.
Another interesting feature is some of these
organisms produce a toxin which can be deadly.
Shellfish because they are filter feeders store
these toxins. That is why it is not good to dig
clams in a month without an R. These also
cause a characteristic red tide.
7
The phylum Chrysophyta are also known as the
golden algae because of their yellow pigments.
The store food in the form of oil instead of
starch.
They have cell walls made of pectin instead of
cellulose.
Some have cell walls made of glass and these
include the diatoms . Diatoms because they are a
mild abrasive are used in toothpaste and lens
polish.
