groove. The primary photosynthetic pigment is corophy
of glucose may be stored as starch or lipids.
When nutrients are abundant, certain marine dinoflagellates undergo large population
"blooms" in such enormous numbers that they color the ocean waters a deep reddish hue
for miles. The toxins and anoxic conditions produced by these red tides often poison
massive numbers of fish and make shellfish in these areas unfit for human consumption.
PROCEDURE
1 Obtain a prepared slide of dinoflagellates and examine
with medium or high power.
2 Look for the two perpendicular grooves and the rigid
cellulose plates. It may even be possible to make out
flagella on well-prepared specimens (Figs. 6.5 and 6.6).
3 Next make a wet mount of a living dinoflagellate (either
Peridinium or Ceratium) and examine it under medium
or high power.
4 If the organisms are moving too quickly to observe
easily, make another slide, this time adding a drop
of methylcellulose, Protoslo, or Detain to slow their
movement.

Expert Solution
Step 1
Dinoflagellates are protists that play an important role in ocean ecosystems, and they possess certain unique features that allow them to survive in their environment. In this essay, we will explore the external features of dinoflagellates, including their cellulose plates and flagella, and compare their movement to other protists.
