Download - Kingdom protista
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
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
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
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
FUNGUSLIKE PROTIST
They are saprophytic.
They derived food and energy by breaking down dead organic matter
Examples are slime molds
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)
