Kingdom Protista

A diverse group of eukaryotic organisms that are predominantly unicellular and do not fit into the other kingdoms (Plants, Animals, Fungi).

Autotrophic Nutrition

Organisms that produce their own food via photosynthesis or chemosynthesis, using sunlight or inorganic chemicals for energy.

Heterotrophic Nutrition

Organisms that require the consumption of other organisms for energy and derive carbon from organic compounds.

Mixotrophic Nutrition

Organisms that can switch between autotrophic and heterotrophic modes of nutrition.

Protozoa

Mostly unicellular and heterotrophic organisms that specialize in locomotion and are further classified into phyla such as Sarcodina, Mastigophora, Ciliophora, and Apicomplexa.

Sarcodina

A phylum of protozoa characterized by irregular structures using pseudopodia for movement; example includes Amoeba.

Mastigophora

A phylum of protozoa that utilize flagella for movement; includes species like Trypanosoma and Giardia.

Ciliophora

A phylum of protozoa with well-defined shapes and cilia for movement; example includes Paramecium.

Apicomplexa

A phylum of protozoa that are complex, non-motile in mature stages, and often parasitic; an example is Plasmodium, which causes malaria.

Algae

Photosynthetic organisms that can be unicellular or multicellular, classified into divisions based on their photosynthetic pigments.

Euglenophyta

A division of algae characterized by the presence of a pellicle and eyespot, primarily found in freshwater; example includes Euglena.

Chlorophyta

A division of algae that contains chlorophyll a and b, with cellulose cell walls; mostly found in freshwater; example includes Chlorella.

Cyanobacteria

Photosynthetic prokaryotic organisms that thrive in various environments including extreme conditions; examples include Anabaena and Nostoc.

Lab Demonstration

An experimental procedure to observe microorganisms, typically involving a pond water sample and a microscope.
