Full Answer

In a unicellular organism, one cell performs all life-functions for the organism. This includes ingestion of nutrients, digestion and breakdown of nutrients and cellular respiration. Eukaryotic cells have membrane-bound organelles that perform specialized functions in the cell. For example, the nucleus of the cell stores the genetic information in the cell, mitochondria are responsible for cellular respiration and energy production, and ribosomes are responsible for putting together proteins. By contrast, prokaryotic cells do not have membrane-bound organelles.

  • Q:

    How are living things classified?

    A:

    All organisms belong to one of five kingdoms: animal, plant, moneran, fungi and protist. All living organisms fall into specific categories using taxonomy, which groups all living things into groups based on biological characteristics and traits. Taxonomy itself classifies as a distinct branch of science, classifying living creatures into general categories and more specific groups.
