Protists 55 Living Organisms Individual Cultures 152525 Spirogyra 152655 Volvox aureus Green Algae Each unialgal culture contains enough material for a class of 30 students. For your convenience, we list culture media, optimum growth temperatures, and either Low or High light levels (Low: 50 to 100 foot-candles of fluorescent light or fluorescent light from the ceiling; High: 200 to 400 foot-candles of fluorescent light 18 to 24" from the culture). Spirogyra Probably the most widely known of all freshwater algae, we recommend this filamentous green alga as a means of introducing students to making and viewing slides of algae. The name Spirogyra refers to its chloroplasts, which form spirals in each of its cells. Note: Should not be shipped over a weekend. Carolina recommends that you request your order to arrive on a Wednesday, Thursday, or Friday (or even a Saturday) to avoid weekend shipping. 152525 Per culture $8.70 Volvox aureus This colonial green alga forms spherical colonies consisting of hundreds of biflagellate cells. The coordinated beating of the flagella propels the colony through the water with a graceful rolling motion. Recommended as an example of colonial algae. Note: Should not be shipped over a weekend. Carolina recommends that you request your order to arrive on a Wednesday, Thursday, or Friday (or even a Saturday) to avoid weekend shipping. 152655 Per culture $8.70 Chlorella A nonmotile freshwater green alga that is spherical in shape. Used in AP® Biology Lab 12 to measure primary productivity under different light conditions. Interesting history as a potential human food source. 152069 Per culture $8.70 *These species should not be shipped over a weekend.
