Answer:
Organization helps us make sense of our surroundings. Some people organize their sock drawers
by color. Books in a library are often organized by topic. Food in a grocery store is organized so we
to know just where to find something.
For scientists, organization is an essential tool. The organization of similar organisms into groups
helps scientists understand how living things are related. It also allows scientists to communicate
about all forms of life. For example, suppose a scientist in the United States writes about a specific
group of animals. Other scientists around the world will know exactly which group of animals the
writer is referring to. But, how do scientists decide which organisms to group together? Do they use
a particular process?
Scientists classify organisms in different ways.
Scientists organize the living world using a process called taxonomy, which is the science of
classifying organisms based on shared structures, functions, and relationships to other organisms.
For example, organisms can be classified based on their cellular
structure. Organisms that have nuclei are eukaryotes. Eukaryotes
also have organelles, or specialized structures bound in a
membrane. They are in a different group than prokaryotes, which
are organisms that do not have nuclei. Also, many unicellular
organisms are in a different group than multicellular organisms.
For example, bacteria are unicellular organisms. They are in a
different group than animals, which are multicellular. Living things also can be classified
according to the way in which they
obtain food. Think about the
differences between plants and
animals. Plants make their own food and are called autotrophs. Animals must consume other
organisms and are called heterotrophs. This difference classifies
plants and animals into two separate groups.
Method of reproduction can be used to classify organisms into
even smaller groups. The two main reproductive methods are
asexual and sexual reproduction. In asexual reproduction, only
one parent is involved in producing offspring. In sexual
reproduction, two parents are involved: a male and a female
