LS Chapter 2 Notes
Classification
Biologists organize living
things into groups:
 This is called
CLASSIFICATION
(group things based on
their similarities)
TAXONOMY is the science
of how living things are
classified. Helpful because
once an organism is classified
scientists will know a lot
more about that organism.
Activity:
KAZ is a new fish.
What do you know
about KAZ based on its
classification?
(It lives in water, has
bones, scales, gills,
etc.)
Q – How would you
classify a sunflower,
Robin, lizard, Blue Jay
and a tree?
Carolus Linnaeus –
placed organisms in
groups based on their
observable features.
 BINOMIAL
NOMENCLATURE
(Two name system)
Genus and species
1st word is the
organisms
scientific name –
its Genus
2nd word
describes its
distinctive features
(where it lives or its
appearance)
Together the two
words indicate a
unique species
species
This is a group of similar
organisms that can mate with
each other and produce
offspring that can also mate
and produce offspring.
Homo sapiens
Homo = man sapiens = wise
(Man that is wise)
Q – What does binomial
nomenclature mean?

Domains and Kingdoms
Bacteria/Monera can be
both Autotroph and
Heterotrophs. The are
prokaryotes – lack a nucleus
Archaea – unicellular
prokaryotes (live at the
bottom of the ocean near hot
springs or extreme
environments). They can be
both auto and hetero.
Structure and chemical
makeup are different then
Eubacteria.
Five Kingdom System
(Lowest to highest)
1. Monera – this is the
simplest of organisms,
almost all microscopic.
Each individual is just one
prokaryotic cell—has no
nucleus or organelles.
Some monera can produce
their own food by
photosynthesis, but many
cannot. Bacteria and bluegreen bacteria belong to
the Monera kingdom.
Eukaryote – are cells that
contain a nucleus.
2. Protists – eukaryotic
organisms. Can not be
classified in animal,
plant, or protist kingdom.
They are both autotrophic
and heterotrophic. Most are
unicellular but some can be
multicelluar such as some
types of algae.
3. Fungi – mushrooms,
molds, mildew. Most are
multicellular eukaryotes.
All fungi are heteotrophs.
Most feed by absorbing
nutrients from dead or
decaying organisms.
4. Plants –
multicelluar/eukaryotes.
Most live on land.
They are autotrophs –
make their own food.
5. Animals – are
multicellular/eukaryotes.
They are heterothophs
because they must obtain
their food.
