|
Chlorophyta, Rhodophyta, and Phaeophyta?
|
Green, red and brown algae
|
|
|
Why are cyanobacteria not considered to be a algae anymore?
|
Because they are not Eukaryotes
|
|
|
Endosymbiotic theory of the origin of photosynthetic eukar?
|
A cyanobacteria ingested a photosynthetic thing via endosymbiosis, and through whatever fluke, there was a mutualism about them that made it work. Led to the origins of photosynthetic eukar.
|
|
|
What is an angiosperm?
|
Flowering plant
|
|
|
Phycobilins?
|
The fluresce. Used in immunofluroessence. They are chromospores, which are light capturing molecules.
Found in algae, and in the chloroplasts of the cyanobacteria |
|
|
Three broad classes of photosynthetic pigments:
|
Chlorophylls: Green pigment. Important for photosynthesis.
phycobilins. Carotonoids: Orange photosynthetic pigment important for photosynthesis |
|
|
In lab, where did we get our cyano, rhodo, phaeo, and chloro?
|
Cyano = Arthrospira, marine species commercially cultivted in large saltwater ponds
Rhodo = Porphyra or Palmaria (dulce), both sold in health food stores. Both dried, edible seaweed. Phaeo = Fucus sp., seaweed Chloro = Chlorella. Seaweed. Usually sold as a health food supplement. |
|
|
Accessory vs. primary pigments in this lab?
|
The chlorophyll a is he primary, and all theo thers are the accessory. They catch light at different wavelengths than a, then transfer the light energy to it.
|
|
|
Significance of knowing the various colours of algae found at varoious depths?
|
Different wavelengths pentrate the water at varying lengths. Thus blue/green penetrate the furthest, therefore you would expectate to only find that type algae at the bottom of the ocean, since they have a competitive advantage in that niche. Red/yellow penetrate the least, so you would expect them to be found closer to the surface.
|
|
|
TLC?
|
Thin layer chromatography. Basically, strip with stuff on it (silica gel) is immersed into a solution that then has the solution drawn up into it by capilliary action. Because different parts of the solution ascend at different rates, a separation is achieved.
