This is all about Kingdom Protista

2. • Kingdom Protista is a diverse group of
eukaryotic organisms. Protists are unicellular,
some are colonial or multicellular, they do not
have specialized tissue organization. The simple
cellular organization distinguishes the protists
from other eukaryotes. Some have flagella or
cilia for locomotion. Reproduction in protists is
both asexual and sexual. They live in any
environment that contains water.

3. Protozoans - animal-like single-celled
organisms.
Algae - plant-like single or multi-celled
organisms.

4. • Protists that have resemblance to
animals are known as protozoans.
They in moist and watery
environments. The characteristics
similar to animals are - their ability to
move and their inability to produce their
own food (heterotrophs). They differ
from animals being unicellular while
animals are multicellular.

5. • Sacordinians - move using pseudopod.
• Zooflagellates - move using flagella.
• Ciliaphorans - move using cilia.
• Sporozoans - forms spores.

6. • The movement in sarcodinians is by
extending lobes of cytoplasm known as
pseudopodia. The pseudopodia is used
for movement and feeding. During the
formation of the pseudopodia the
cytoplasm streams into the lobe causing
the lobe to 'ooze' and grow. Because of
this the pseudopodians have a 'blob like
appearance.

8. • These protozoans move with the help of
flagella. Most of them are parasitic. Many
flagellates are seen in the intestine of
humans, in termites and other animals,
some flagellates are harmful.

10. • Protozoans of this phylum move with hair
like structures called cilia. The movement
of cilia is paddle like, it sways back and
forth for movement and fast beating of the
cilia causes movement of the organism.
The cilia is also used to sweep food
particles into the organism.

12. • All members of this phylum are non-motile
and parasitic. They forms spores and
hence the name sporozoa. They lack
locomotory structures and they are
carried in their hosts by their body fluids.
Many sporozoans causes serious diseases
in humans.

14. • Plant-like protists have chlorophyll like that
in plants. The green substance in their
cells enable them to make food by
photosynthesis. The plant-like protists are
the major food source and primary
producers for water organisms.

15. • The green algae include unicellular and
multicellular algae. Body is sheet-like
thallus. They have cell walls made of
cellulose and pectin.

17. • Red algae are mostly large and
multicellular. They grow in oceans. The
algae 'Nori' and Gelidium are used as food,
in parts of Asia. Carragean and agar are
glue-like substances in red-algae.

19. • Brown algae are multicellular. They grow
on rocks in shallow water of the sea. Large
brown algae are called kelps. The brown
algae growing on rocks are known as
rockweed.

21. • 'Chryso' means 'color of gold'. There are
three types of golden-algae: yellow-green
algae, golden brown algae, diatoms.
• Diatoms are the most abundant and are
found in seawater and freshwater habitats.
The shell of diatoms are made of silica.

23. • It contains of species of one-celled algae
called dinoflagellate which means 'spinning
swimmers'. They store food in the form of
starch and oils. Almost all species like in
marine water.

25. • Slime Molds - Slime molds are saprophytic
protists. They are very bright in
appearance. They live in moist soil,
decaying plants and trees. They are single-
celled organisms.

27. • The slime molds are important to ecosystems
because they are decomposers, which
release vital nutrients back into
the environment.
• Protists serve numerous purposes in the
ecosystem including producing between 70
and 80 percent of the world’s oxygen, being a
main food source for aquatic animals and a
major decomposing agent of dead material.
