NEET BIOLOGY

Detailed explanation-1: -So, the correct answer is ‘locomotory structures’

Detailed explanation-2: -Locomotion. Protozoa move in the environment in three different ways: ameboid movement, flagella, and cilia. The ameboid movement is typical of ameboid protozoa (see below) and some other forms. Movement is achieved by cytoplasmic protrusions known as pseudopodia.

Detailed explanation-3: -Protists were traditionally subdivided into several groups based on their physical similarities to the “higher” kingdoms of Animals, Plants, and Fungi. For example, the unicellular, “animal-like” protozoa, the “plant-like” algae, and the “fungus-like” slime molds and water molds are all protists.

Detailed explanation-4: -All the single celled, eukaryotic organisms come under the category of protozoans. Most of them have heterotrophic mode of nutrition while some of them have autotrophic mode also. There are three major forms of movement in protozoans which are Flagellar, Ciliary, and Amoeboid.

Detailed explanation-5: -On the basis of light and electron microscopic morphology, the protozoa are currently classified into six phyla.
