Biology is a natural science
concerned with the study of life
and living organisms, including
their structure, function, growth,
origin, evolution, distribution,
and taxonomy
What characteristics do define
life?
All living organisms share in a family of basic
characteristics.
1.
Cellular organization
All organisms consist of one or more cells. Often
too tiny to see, cells carry out the basic activities
of living organisms. Each cell is bounded by a
membrane that separates it from its
surroundings.
2. Order
All living things are highly ordered. Your
body is composed of many different kinds
of cells, each containing many complex
molecular structures.
3. Sensitivity
All organisms respond to stimuli. Plants
grow toward a source of light, and your
pupils dilate when you walk into a dark
room.
4. Growth, development, and reproduction
All organisms are capable of growing and
reproducing, and they all possess hereditary
molecules that are passed to their offspring,
ensuring that the offspring are of the same
species.
5. Energy utilization
All organisms take in energy and use it to
perform many kinds of work. Every muscle in
your body is powered with energy you obtain
from the food you eat.
6. Evolutionary adaptation
All organisms interact with other organisms and
the environment in ways that influence survival,
and as a consequence, organisms evolve
adaptations to their environments.
7. Homeostasis
All organisms maintain relatively constant internal
conditions, different from their environment, a
process called homeostasis.
Hierarchial
‫التسلسلي التعضي‬
Organization:
The organization of the biological world is
hierarchial-that is, each level builds on the level
below it.
1. The Cellular Level
At the cellular level, atoms ‫الذرات‬, the fundamental
elements of matter, are joined together into
clusters called molecules ‫الجزيئات‬. Complex
biological molecules are assembled into tiny
structures called organelles ‫ العض يات‬within
membrane-bounded units we call cells ‫الخليا‬.
2. The Organismal Level:
Cells are organized into three levels of
organization. The most basic level is that of
tissues, which are mostly made of groups
of similar cells that act as a functional unit.
Tissues, in turn, are grouped into organs.
At the third level of organization, organs
are grouped into organ systems.
3. The Population Level ‫مستوي العشيرة‬
Individual organisms are organized into several
levels within the living world. The most basic of
these is the population, which is a group of
organisms of the same species living in the same
place.
All the populations of a particular kind of
organism together form a species, its members
similar in appearance and able to interbreed.
At a higher level of biological organization, a
biological community consists of all the
populations of different species living together
in one place.
