Protists - Living Material
Live specimens are used for a wide variety of studies including studying the physiological effects of drugs on a specimen’s heartbeat and temperature on metabolism, the locomotion of microscopic organisms, and studying plant respiration, photosynthesis, plosmolysis, and more. Algal cultures form colonies of cells that are extremely easy to visualize for better understanding of cell walls and plastids, and many live specimens reproduce rapidly for quick turnover between successive tests.

Ward's® Marine Planktonic Debris
Specially Prepared “Real-Life” Combinations
The world is teeming with a wide variety of microlife, making studying samples of pond water complicated especially for the beginning student. To lessen the confusion, WARD’S has prepared different culture mixes that reflect protist combinations that occur in the real world, yet eliminates the hundreds of other life-forms found in a collected sample. Comes with a dichotomous key and either the Working with Algae or the Working with Protozoa manual. Supplied in a single jar.
Contents: Ocean scum.
