What are organisms?What are organisms?
In biology, organisms is a living thing. All organisms are capable of response to stimuli
reproduction, growth, and development, and maintenance of homeostasis as a stable whole.
Viruses are not typically considered to be an organism because they are incapable of “independent” reproduction or metabolism.
An organism’s life span is one of the basic parameter. Some organisms can live as short as one day while others, like plants, can live up to a thousand years.
Organisms are semi-closed chemical systems.

Organisms bred for specific characteristics
Organisms bred for specific characteristics
All members of the species sapiens are in theory, genetically able to interbred.
Several species may belong to a genus but the members of different species within a genus are unable to interbred, produce fertile offspring.
Homo has one surviving species, sapiens.

Some characteristics of an organism are the result of a combination of interaction with the
environment and genetic information

Organisms are complex system of chemical compounds, which through interaction with each other and the environment, plays a wide variety of roles.
They are individual units of life but they are not closed to the environment around them.
To operate, they constantly take in and release energy. Autotrophy produces usable energy in the form of
organic compounds using light form the sun or inorganic compounds while heterotrophy take in organic compounds from the environment.
Primary chemical element in these compounds is carbon.

Innate vs.. learned behaviors
Innate vs.. learned behaviors
Innate behaviors - behavior determined by the “hard-wiring” of the nervous system. Inflexible, a given stimulus triggers a response.
Learned behavior - behavior that is more or less permanently altered as a result of the experience of the individual organism. For example: learning to play baseball well. Tax reflexes: when you touch a hot object, you quickly pull
your hand away using the withdrawal reflex. Instincts: complex behavior patterns which, the reflexes
are inborn. Rather inflexible and valuable at adapting the animal to its environment.

Organisms are composed of cells, which are the
fundamental units of life
Organisms are composed of cells, which are the
fundamental units of lifeAll existing organisms share certain traits
including cellular structure and genetic codes.
scientist interpret this to mean that all existing organisms share a common ancestor which had already developed the most fundamental cellular processes. But these is no sciencetific consensus on the relationship of the three domains of life: Archaea, Bacteria, and Eukaryota (or the organs of life).

Unicellular vs.. multicellular
Unicellular vs.. multicellular
Organisms are either unicellular or multicellular not both.
Unicellular - single celled or to be composed of as in human, many billions of cells grouped into specialized tissues and organs. Can survive without the help of other cells.
Multicellular - many celled, described any organisms made up of more than one cell.
