2. Protists has a more complex
structure, function, behavior and ecology than
bacteria
They have specialized organelles for
feeding, digestion, excretion, respiration, coordinatio
n, 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
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
11. FUNGUSLIKE PROTIST
They are saprophytic.
Theyderived food and energy by
breaking down dead organic matter
Examples are slime molds
12.
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)
