Activity: Optional activity: to investigate examples of life forms from each kingdomAim:To investigate examples from each kingdomInstructions::- Research one beneficial and one harmful application of one member from each
kingdom, with examples from their use in South Africa. Students can be
grouped into smaller groups and each one is given one kingdom to research.
(Use http://www.arkive.org as a research tool for your favourite animal or plant or
http://bugscope.becnkman.uiuc.edu/ for nice pictures of insects). Results can be pre-
sented in the form of a poster. - Go to your nearest supermarket or garden and find one representative organism for
each kingdom. Present this information by drawing a diagram
Dichotomous Key DUMMY
Adichotomous keyis a tool that taxonomists often use to classify organisms correctly. It is a
form of hierarchical grouping that involves making decisions in a series of steps, from general
differences to very specific differences. It is called adichotomous key because there are
alwaystwochoices. There is a very specific way to set up a dichotomous key. For instance,
one must always move from the general to the specific, and one must always ensure that
the two choices in the decision tree aremutually exclusiveandjointly exhaustive. Mutually
exclusive means that there cannot be overlap between the two options, as this would result in
wanting to place an organism in two groups. Jointly exhaustive means that your two options
must cover all possibilities, otherwise you won’t be able to place an organism in either of
the groups.Activity: Identifying arthropods using a dichotomous naming keyAim:To use a dichotomous key to identify arthropods.Table of specimens:308 10.4. Five kingdom system
