Characteristics of Living Things Characteristics of Living Things
•Cellular structure•Metabolism •Nutrition •Growth •Excretion•Including nucleic acids•Movement or locomotion•Sensitivity or responsiveness•Reproduction•Capacity to evolve
CELLULAR STRUCTURE
Organism
Unicellular (Single cell)
Multicellular (More than one cell)
Living things are made up of one or more cells. Cells are the smallest units of an organism.
NUTRITION
•All living things directly or indirectly depend on other organisms for energy and food sources.
•All living things have complex structural organization based on instructions in DNA molecules.
INCLUDING NUCLEIC ACIDS
•All living things are able to move in order to provide themselves sources for their needs.
MOVEMENT OR LOCOMOTION
•All living things are open to changes in their DNA. These changes are called mutations that lead to evolution.
CAPACITY TO EVOLVE
The condition of a constant internal environment in an organism is called homeostasis.
Ex: Regulation of blood sugar level
Regulation of body temperature
