Across
- 3. Red algae experienced an “evolutionary___________” – an event in which the population of red algae and their genomes shrank drastically.
- 9. In cyanobacteria and red algae, a hemispherical or discoidal structure on the surfaces of thylakoids that contains the pigment structures.
- 11. A proteinaceous region in the plastids of many types of algae; known in some cases to contain RUBISCO and commonly associated with formation of storage compounds; the number per cell may be used to differentiate Ulva species.
- 14. A gelatinous polysaccharide extracted from the walls of various red algae that is used as a gelling agent and for microbial plates; the highest quality of this product is from Gelidium.
- 16. The cell surface features of dinoflagellates that include the external cell membrane, alveoli, and thecal plates inside the alveoli (if it’s “armored”)
- 17. An elongate slit in one or both valves of many pennate diatoms that allows for rapid movement
- 18. The stealing of chloroplasts by sea slugs. The word is derived from “Kleptes” which is Greek for “thief”
- 19. a compound that absorbs UV radiation and is yellow-brown in color in cyanobacteria
Down
- 1. The most abundant benthic microalgal group in Charleston estuaries that serve as a food source, stabilize sediments, and are important for biogeochemical cycling
- 2. an alternation of sporic generations with distinctive gametophyte and sporophyte phases
- 4. The order of green algae that is siphonous and multinucleate; contains genera such as Bryopsis, Caulerpa, and Halimeda
- 5. A flagellate spore
- 6. The genus of dark-green, spiral-shaped cyanobacteria that contains phycocyanin and is used as a supplement because of its supposed health benefits.
- 7. A pigment that gives a golden-brown or brown pigmentation to diatoms, brown algae, and some other photosynthetic stramenopiles.
- 8. Unicellular golden-pigmented cells (usually dinoflagellates) that are endosymbiotic in marine animals, including reef-building corals; probably the most common alga on tropical coral reefs.
- 9. One of the major diatom frustule types; exhibits bilateral symmetry of valve ornamentation.
- 10. The process by which one organism becomes stably resident within the cell or body of another, known as the host, to form a chimera; this theory explains the evolutionary origin of algal plastids
- 12. A condition whereby a species becomes excessively abundant usually causing ecological or economic harm
- 13. A cell produced by diatoms that undergoes enlargement, compensating for the reduction in size that often occurs during population growth; commonly also the zygote of diatoms.
- 15. a blade composed of true tissue, such as Ulva
