Humans, animals, and pretty much all living things need to perpetuate their genes by means of reproduction, whether it is asexual or sexual.
We need to animals need to eat and sleep, but you can just categorize this as a metabolic process. Plants need Nitrogen and CO2 and sunlight, to undergo metabolic processes and make glucose (another metabolic process). We also must be able to maintain an equilibrium while conducting metabolism (homeostasis).
We need to be able to sense the environment around ourselves to survive.
If you look at simple organisms, they are often able to detect different chemicals and know to be attracted or stay away from certain substances.
All living things are made up of cells.
The system of nomenclature used today is based on the binomial system of nomenclature, developed by Linnaeus<span> in the late 1700's. The binomial system of nomenclature is structured so that the scientific name of a plant consists of two names: (1) the genus or generic name, and (2) the specific epithet or species name. There are rules to follow when writing a scientific name.</span>
