Solution:

Euglenoids have a protein rich layer called pellicle which makes their body flexible. They have two flagella, a short and a long one. Slime moulds are saprophytic protists. The body moves along decaying twigs and leaves engulfing organic material. During unfavourable conditions, the plasmodium differentiates and forms fruiting bodies bearing spores at their tips. The spores possess true walls. They are extremely resistant and survive for many years, even under adverse conditions. The spores are dispersed by air currents. Dinoflagellates are mostly marine and photosynthetic. They appear yellow, green, brown, blue or red depending on the main pigments present in their cells.
