Detailed explanation-1: -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 eukaryote, the cells of these species have a nucleus and membrane-bound organelles.

Detailed explanation-2: -protist, any member of a group of diverse eukaryotic, predominantly unicellular microscopic organisms.

Detailed explanation-3: -Kingdom Protista includes all eukaryotes that are not animals, plants, or fungi. It consists of both single-celled and multicellular organisms.

Detailed explanation-4: -A Protist is a unicellular, eukaryotic organism. This means that they are made up of one cell and that cell contains a membrane bound nucleus with other specialized organelles. Protists are a part of the kingdom Protista, which includes organisms such as algae and various protozoans.

Detailed explanation-5: -Protists can be unicellular (single-celled) or multicellular (many-celled). Seaweed and kelp are examples of multicellular, plant-like protists. Kelp can be as large as trees and form a “forest” in the ocean (Figure below). Macrocystis pyrifera (giant kelp) is a type of multicellular, plant-like protist.
