1. Brown algae
Multicellular protistans placed in the Division Phaeophyta, includes kelp.

2. Chlamydomonas
A genus of green algae consisting of more than 600 species worldwide, living in marine, freshwater, soil, and even snow environments. They are single cell ed eukaryotic organisms ranging from 5 to 100 micrometers long which can be roughly spherical, egg shaped, or elliptical. Most species have two flagella (coming out the same side) for swimming. Most of the time they are haploid and reproduce by dividing into two ( binary fission ); when they are stressed they can form gamete s which fuse to form diploid cyst s which later divide into four haploid cells. Taxonomically they have been classified under plants, animals, and protist s. Several species from this genus are important model organisms for the study of cell biology , molecular biology , genetics , plant physiology , and biotechnology . The species most commonly used in scientific experiments is Chlamydomonas reinhardtii (also known as C. reinhardi or C. reinhardii).

3. Chlorophyll c
An accessory chlorophyll found in some protistans .

4. Chrysophytes
protistan division that is referred to as the golden brown algae; includes the diatoms.

5. Dinoflagellates
Single-celled to colonial protistans characterized by two flagella , one girdling the cell and the other trailing the cell. Some dinoflagellates exist in coral, in a symbiotic relationship. These dinoflagellates are termed the zooxanthellae. Other dinoflagellates occur in such high numbers that the water is colored red, a phenomenon known as a red tide .

6. Eukaryote
A type of cell found in many organisms including single-celled protists and multicellular fungi, plants, and animals; characterized by a membrane-bounded nucleus and other membraneous organelles; an organism composed of such cells. The first eukaryotes are encountered in rocks approximately 1.2-1.5 billion years old.

7. Foraminifera
Single-celled protists that secrete a shell or test. Accumulations of the shells of dead foraminifera and other microscopic sea creatures form chalk deposits.

8. Golden brown algae
Common name applied to the protistan division Chrysophyta.

9. Kingdom
The topmost taxonomic rank, immediately above phylum or division. This dictionary recognizes five biological kingdoms: Monera , protista , Fungi , Plantae , Animalia

10. Kingdom Protista
This kingdom is composed of single-celled (sometimes multicellular), eukaryotic organisms. protists are more complex than bacteria and include protozooan s and some types of algae .
