Protists have more complex structures and functions than bacteria, including specialized organelles. They can be classified as plantlike, funguslike, or animal-like. Three groups of algae - green algae, kelp, and red coral algae - are considered plantlike protists. Plantlike protists also include phytoplankton like euglena and diatoms that provide food for aquatic animals. Funguslike protists break down dead organic matter as saprophytes. Animal-like protists, also called protozoans, are heterotrophic and include zooflagellates, sporozoa, and ciliates like trypanosoma, amoeba, plasmodium,

2.  Protists has a more complex structure, function,
behavior and ecology than bacteria
 They have specialized organelles for feeding,
digestion, excretion, respiration, coordination, and
locomotion
 They may be classified as plantlike, funguslike, or
animal-like

3.  Three groups of algae which where traditionally
classified as plants are now considered as protist
 They represent the multicellular plant-like protist
 Protist are not considered as plants because they
do not have structures that protect their
gametes and zygote

4.  They are not considered animals either,
because they do not undergo embryonic
development
 Neither they are not fungi because they
do not have chitin in their cell walls as
true fungi have

5. GREEN ALGAE

6. KELPS

7. RED CORAL ALGAE

8. PLANTLIKE PROTIST
 Phytoplanktons, a varied group of single-
celled photosynthetic organisms that float
near the surface of fresh and salty water
 Provide food for most aquatic animals

9. PLANTLIKE PROTIST
 Examples are euglena, dinoflagellates,
golden-brown algae and diatoms

11. FUNGUSLIKE PROTIST
 They are saprophytic.
 They derived food and energy by
breaking down dead organic matter
 Examples are slime molds

13. ANIMAL-LIKE PROTIST
 They are also called Protozoans
 They are all heterotrophic protists
 Animal-like protists includes zooflagellates
(trypanosoma), sarcodina (amoeba), sporozoa
(plasmodium) and ciliates (paramecium)
