NEET BIOLOGY

Detailed explanation-1: -Protozoan organisms show both heterotrophic and autotrophic nutrition. These organisms can be motile or non-motile. Show movement with the help of flagella and cilia.

Detailed explanation-2: -The nutrition of all protozoa is holozoic; that is, they require organic materials, which may be particulate or in solution. Amebas engulf particulate food or droplets through a sort of temporary mouth, perform digestion and absorption in a food vacuole, and eject the waste substances.

Detailed explanation-3: -Introduction. Protozoa are unicellular, heterotrophic, eukaryotic organisms comprising four organization types: amebae, flagellates, ciliates, and parasitic sporozoans.

Detailed explanation-4: -Heterotrophic nutrition is the mode of nutrition where the organism is unable to prepare its food and hence, depends upon plants or other organisms for nutrition.

Detailed explanation-5: -All types of nutrition are found in protozoa namely holophytic nutrition, holozoic nutrition, saprozoic nutrition, mixotrophic nutrition and parasitic nutrition.
