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

GREEN ALGAE

KELPS

RED CORAL ALGAE

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

PLANTLIKE PROTIST

Examples are euglena, dinoflagellates, golden-brown algae and diatoms

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)
