NEET BIOLOGY

Detailed explanation-1: -Protists such as moulds and algae are multicellular, i.e., they are made up of more than one cell. Amoeba, paramecium and euglena are unicellular organisms belonging to kingdom Protista.

Detailed explanation-2: -Under the five-kingdom classification given by R.H. Whittaker, prokaryotic organisms are placed in the kingdom Monera. Kingdom Monera has unicellular prokaryotic organisms. They do not have a well-developed nucleus or advanced cell, neither they possess any cell organelles.

Detailed explanation-3: -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-4: -Protists are unicellular, eukaryotic organisms. Membrane-bound organelles are present in them and cell wall may or may not be present. There are plant-like, animal-like and fungi-like protists. Examples include algae, protozoans and slime molds respectively.

Detailed explanation-5: -Kingdom Protista Protists are a group of all the eukaryotes that are not fungi, animals, or plants. As a result, it is a very diverse group of organisms. The eukaryotes that make up this kingdom, Kingdom Protista, do not have much in common besides a relatively simple organization.
