Concept explainers

Prokaryotic evolution

The term evolution means the gradual change or a transformation from a simple or primitive state to a complex or advanced state. Prokaryotic evolution is a concept that involves the evolution of the form and function of most primitive organisms (prokaryotes) through several stages and changes to form diverse life as a part of organic evolution.

The organism seems to make its own food by utilizing its chlorophyll. The organism is only one cell big and is capable of moving freely. In addition to chlorophyll, the organism has several other organelles, including a nucleus. Which kingdom does your organism belong to?
