Question

five important points of protists​

Answer 1

Answer:

These are usually aquatic, present in the soil or in areas with moisture.

Most protist species are unicellular organisms, however, there are a few multicellular protists such as kelp. Some species of kelp grow so large that they exceed over 100 feet in height. (Giant Kelp).

Just like any other eukaryotes, the cells of these species have a nucleus and membranebound organelles.

They may be autotrophic or heterotrophic in nature. An autotrophic organism can create their own food and survive. A heterotrophic organism, on the other hand, has to derive nutrition from other organisms such as plants or animals to survive.

Symbiosis is observed in the members of this class. For instance, kelp (seaweed) isa multicellular protist that provides otters, protection from predators amidst its thick kelp. In turn, the otters eat sea urchins that tend to feed on kelp.
