Are cells alive

There are 7 criteria for an organism to be considered alive:

(a) Homeostasis: Regulation of the internal environment to

maintain a constant state

(b) Organization: Being composed of one or more cells, which are the basic units of life.

(c) Metabolism: Consumption of energy by converting nonliving material into cellular components (anabolism) and

decomposing organic matter (catabolism). Living things

require energy to maintain internal organization (homeostasis) and to produce the other phenomena

associated with life.

(d) Growth: Maintenance of a higher rate of synthesis than

catalysis. A growing organism increases in size in all of its

parts, rather than simply accumulating matter. The particular

species begins to multiply and expand as the evolution

continues to flourish.

(e) Adaptation: The ability to change over a period of time in

response to the environment. This ability is fundamental to

the process of evolution and is determined by the

organism's heredity as well as the composition of

metabolized substances, and external factors present.

(f) Response to stimuli: A response can take many forms, from the contraction of a unicellular organism when touched to complex reactions involving all the senses of higher

animals. A response is often expressed by motion, for

example, the leaves of a plant turning toward the sun or an

animal chasing its prey.

(g) Reproduction: The ability to produce new organisms.

Reproduction can be the division of one cell to form two new

cells. Usually the term is applied to the production of a new

individual (either asexually, from a single parent organism,

or sexually, from at least two differing parent organisms),

although strictly speaking it also describes the production of

new cells in the process of growth.

Because of these factors, cells are alive.
