Describe the division of living organisms into different groups in biology?
The unicellular organisms that do not have distinct nuclei are grouped as prokaryotes, for example, bacteria. The unicellular or simple multicellular organisms with distinct nuclei are called protists e.g. Euglena, Paramecium, Green algae, etc.
Fungi e.g. mushrooms are multicellular, heterotrophic, and absorptive in their mode of nutrition. Plants e.g. mustard are multicellular autotrophic organisms that develop from embryos. Animals e.g. frogs are multicellular heterotrophic organisms that ingest food.
