Hint: The term ‘Protista’ is derived from the Greek word called “protistas”, meaning “the very first“. These organisms are usually unicellular and the cell of these organisms contains a nucleus which is bound to the organelles in the cell. Some of them even possess structures that aid their locomotion like flagella or cilia.
Complete answer:
Protists are unicellular in nature but can also be found as a colony of cells. Most protists live in water, damp terrestrial environments or even as parasites.
The primary feature of all protists is that they are eukaryotic organisms. This means that they have a membrane-enclosed with a nucleus. Other characteristic features of Kingdom Protista are as follows-
Most protist species are unicellular organisms, however, there are a few multicellular protists that exist such as kelp.
Just like any other eukaryotes, the cells of these species have a nucleus and the membrane-bound organelles.
They may be autotrophic or heterotrophic in nature, an autotrophic organism can create their own food and survive whereas 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 the protista.
Parasitism is also observed in some protists.
Protists exhibit locomotion through the cilia and flagella.
Protists reproduces by asexual means and the sexual method of reproduction is extremely rare and occurs only during times of stress.
Thus the correct answer is option D. B and D
Note:
Protists serve as the foundation of the many food chains. Protists are the primary sources of food for many animals and in some rare cases, Protists are harvested by humans for food and other industrial applications.
