research into the five Kindoms.
• Wikipedia is a good place to start
• http://en.wikipedia.org/wiki/Kingdom_(biology)

You must describe the main characteristics of the
major classification groups. Construct simple
identification keys.

Animalia
A table is a good way to present your information
You will also need to include a key that will help a biologist
identify an organism. You could use one you have
previously made or complete further research from the
internet. It must be you own work – a printed /
photocopied key is not sufficient.
Describe [give a clear description that includes all the
relevant features. Think of it as painting a picture with
words.]

Part 2 - Merit
• Explain the need to classify
organisms
• For this part of the assessment you must
explain the system of classification and
why we need it. You will need to explain
the benefits of the system and possible
drawbacks.
• Research and write out 1 organism’s
Linnaean classification (kingdom,
phylum, class, order, family, genus,
species)
•
Explain [Provide details and give
reasons and/or evidence to clearly
support the argument you are making]
Classification…
• System is based on similarities between
organisms
• Organisms below a group – share common
features (e.g. vertebrate, fungi)
• Naming organisms (scientific) follows a
simple rule. This means that new species
can be given a name
• Biologists can place organisms with similar
characteristics in groups.
• Some features in a group may not seem
obvious. This means that the grouping
system may initially seem wrong.
Part 3 – Distinction
• Discuss the characteristics which
are used to distinguish the major
groups.
• For this part of the assignment You
have to discuss advantages and
disadvantages of the main
characteristics of the five groups.
• Discuss [provide in depth
information about a topic. Explain
arguments for and against. Provide
your own conclusion]

Describe the characteristics
Choose three
characteristics and explain
why it is beneficial to the
organism
Which characteristics are
not beneficial to the
organism?
Presenting the information
in a table will help
organize your coursework.

(estimate)
Monera
• Monera are bacteria and
other mostly tiny, singlecelled organisms whose
genetic material is loose in
the cell.
• Bacteria are very simple
organisms which are made
of cells with no nucleus.
They eat, they are capable
of reproducing themselves,
and they have a membrane
which separates the inside
of themselves from the
outside world. Blue-green
algae are an example of
one kind of bacteria.
Protist
• Protists are a
diverse group of
eukaryotic
microorganisms.
• Organisms (with
nucleated cells)
that are not
considered true
animals, plants,
fungi; includes
algae
Fungi
• Molds, mildews, yeasts,
mushrooms, and puffballs,
a group of organisms
lacking in chlorophyll (i.e.,
are not photosynthetic) and
which are usually nonmobile, filamentous, and
multicellular.
• Some grow in soil, others
attach themselves to
decaying trees and other
plants whence they obtain
nutrients. Some are
pathogens, others stabilize
sewage and digest
composted waste.
Plantae
• An organism that is
not an animal,
especially an
organism capable of
photosynthesis
Animal
• Animals are a major group
of multicellular, eukaryotic
organisms of the kingdom
Animalia.
• Their body plan eventually
becomes fixed as they
develop, although some
undergo a process of
metamorphosis later on in
their life. Most animals are
motile, meaning they can
move spontaneously and
independently. Animals are
also heterotrophs, meaning
they are dependent on
other organisms

Improving Coursework
• Most people had problems with…
• P(a)
Write a simple definition of
Classification
• M(i)
Explain why it is necessary to classify
organisms and the advantages of the
Linnaean system
P(a) – You must achieve this else
FAIL
• Explain why biologists put things into
groups.
• Discuss…
– Similar characteristics within groups
– What happens when a new species is
found
– How organisms below a level have
common features
M(h) – You need this for a Merit
• Why its necessary to classify
organisms.
– Discuss what happens when biologists
find a new organism.
– They look at the features and put it in
the appropriate group based on
Kingdom, phylum, class etc.
– It’s then easy to put new organisms into
groups
– Discuss the language used (Latin) and
why
