Final answer:
Both unicellular and multicellular organisms carry out the processes of life, but in different ways. Unicellular organisms are single-celled and can perform all life functions independently, while multicellular organisms have specialized cells that work together to carry out specific tasks and processes.
Step-by-step explanation:
Both unicellular and multicellular organisms carry out the processes of life. Unicellular organisms, such as bacteria and amoebae, are able to perform all the necessary functions of life on their own, as they are made up of a single cell. Multicellular organisms, on the other hand, have specialized cells that work together to carry out specific tasks and processes.
For example, in multicellular plants, there are different types of cells responsible for functions like photosynthesis or water transport. In multicellular animals, different cells make up organs and tissues that perform specific functions, such as the heart pumping blood or the lungs exchanging gases.
