Protist are eukaryotic cells that can be classified into Algae, Protozoa, Fungi and Slime mold.

Algae are classified as any eukaryotic cells that produce oxygen through photosynthesis and contains chloroplast in the cell.

Protozoa are single cellular eukaryotic cells that do not carry out photosynthesis but use organic carbon that are easily digested for growth.

There are 3 classification of protozoa:

  1. Sarcomastigophora are protozoa with flagella like Trichmonas spp or amoebas.
  2. Apicomplexa are spore forming protozoa. Also known as sporozoas. An example is Toxoplasma spp.
  3. Ciliophora are protozoa with cilia. A example would be Balantidium coli.

There are 2 group of fungus, Mold and Yeast. Both groups are non-photosynthetic eukaryotes, but mould forms mycelium, a network of hyphae which have perforated cross-walls between branches resulting in mould being multicellular and multinucleated. An example of mold is Tinea pedis. Yeast, however, is a single cell organism that does not form mycelium, an example would be Candida spp.

Lastly, Slime mould are eukaryotes classified based on a stage in their life cycle whereby they produced plasmodium, an ameboid multinucleated mass of cytoplasm[1].
