Definition of Biology
Biology (from the Greek words bios
= life and logos = science or
studying). It means the study of life
or living organisms in terms of their
structure, function, distribution,
adaptation, interactions, evolution
and all vital activities.
Life Properties
Despite the difficulty of defining life and determine its
characteristics accurately,
the secret of life lies in the protoplasm
(living material that make up the body cells
of the organism).
protoplasm consists of organic compounds as nucleic
acids, proteins, carbohydrates and fats, but it is
characterized by being living.
The most important characteristic of living
organisms is the ability to conduct the next vital
operations:
1-Nutrition
A vital process that enables the organism
to obtain the necessary energy to carry
out other vital operations.
Nutrition includes the following stages:
a- Nutrient uptake
b- Nutrient Processing
c- Waste elimination
2-Respiration
It is the process of gas exchange.
Inhalation of Oxygen
Exhalation of carbon dioxide.
3-Growth and Reproduction
Growth: Constitutes the total of the biological
processes that lead to increase the size of the
organism.
The reproduction is increasing the number of
organisms.
4- Locomotion
Means the ability of the organism to move from
one place to another in the media where they live
this known as the virtual movement in animals
sometimes some plants exercise this type of
movement as the movement of insect-eaters
plants.
if we look closer under the microscope, we
see the movement of organelles in the cells,
this type of movement is known as
cytoplasmic movement .
Response to the external stimuli:
the Organism responds to external stimuli by
irritability through moving to or away from the
source.
As a result of persistent exposure to this
external source arises the so-called individual
adaptation. Over time, produces the socalled evolution.
