The pattern of organization thesis
Life on earth is composed of
many different structures. The
goal of science is to explain
and identify all the
components. Biology is the
branch of science that aims to
explain life by identifying all
living things, differentiates
between them, recognize their
interactions with each other’s
and with their environments.
Biology recognizes certain
properties of life. These properties distinguish living from
non-living; only living things have these properties and they
include:
organization
metabolism
responsive
reproduction
movements
growth and development
adapting
Organization
The pattern of organization is very important for all living
things to maintain their life. The organization is seen in all
life forms whether the organism is composed of trillions of
cells or it is just a single cell organism. The level of
organization is essential for functions because any changes
in the structure will result in a loss of the function.
Looking at the lowest level of an organization starts with
elements in which different atoms such as carbon,
hydrogen, and oxygen start to organize into molecules such
as water, proteins, carbohydrates, and lipids, the building
process continues when those molecules get organized into
defined structures known as organelles each of them will
have a unique structure and specialized functions.
Organelles make up the next level as they become
organized into one unit called the cell. The cell represents
the basic unit of life as they may exit alone and have all the
properties of life, but they start to group and specialized
into four major tissues, the epithelium, connective, muscular
and nervous tissue. When tissues are organized and
attached according to genetically preset codes and ratios
that result in what is known as an organ, different organs
will be built each with a unique function such as the heart,
stomach, and lung, which then organized into a system
where each system is composed of several organs all of
their function complies as one unit, and finally, several
systems such as the respiratory, digestive, nervous and
lymphatic systems make up one organism.
The organization does not stop at organism, it continues
when a group of organism lived together and depends in
each other forming what known as a population, several
populations usually lived closed and interact with other
creating one community. All the communities in one
geographical area as they interact with non-living things
such as water and mountains will establish a higher level of
an organization called an ecosystem.
