Detailed explanation-1: -Protists are mostly unicellular (one-celled) eukaryotes. A few protists are multicellular (many-celled) and surprisingly large. For example, kelp is a multicellular protist that can grow to be over 100-meters long (Figure below).

Detailed explanation-2: -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-3: -Protists, like fungi, can be unicellular or multicellular. Examples of unicellular protists include amoebas and euglenas. Examples of multicellular protists include many types of algae, including giant kelp. We know that protists can be unicellular or multicellular.

Detailed explanation-4: -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.

Detailed explanation-5: -Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.
