Explain the features that make dinoflagellates different from other phytoplankton. What will be an ideal response?
Most dinoflagellates are single-celled autotrophs. A few species live within the tissues of
other organisms, but the great majority of dinoflagellates lives free in the water. Most have
two whiplike projections called flagella, in channels grooved in their protective outer cell
wall of cellulose. One flagellum drives the organism forward, while the other causes it to
rotate in the water. Although unable to move them against currents, their flagella allow
dinoflagellates to adjust their orientation and vertical position to make the best photosynthetic
use of available light or to move vertically in the water column to obtain nutrients.
Dinoflagellates are the most common source of surface bioluminescence.
