Unicellular organisms must carry out essential life processes to survive, including:
-
Metabolism: They need to perform chemical reactions to convert nutrients into energy and build cellular components.
-
Reproduction: Unicellular organisms reproduce to ensure their population continues, typically through asexual processes like binary fission or budding.
-
Growth: They must grow and develop by increasing in size and synthesizing cellular components.
-
Response to Stimuli: Unicellular organisms must respond to environmental changes to survive, such as moving towards nutrients or away from harmful substances.
-
Homeostasis: They must maintain a stable internal environment, regulating their internal conditions to cope with external changes.
-
Excretion: Unicellular organisms must eliminate waste products generated from metabolic processes.
These processes ensure their survival and proper functioning in their environment.
