Identify the main features used to place organisms into the five kingdoms (animal, plant, fungus, prokaryote, protoctist) and the main vertebrate and arthropod groups. Use simple dichotomous keys.
Which kingdom contains organisms that have cell walls but no chlorophyll, and feed by absorbing nutrients from their surroundings?
Name the kingdom of single-celled organisms that have NO nucleus.
[1 mark]Name the kingdom of mostly single-celled organisms that HAVE a nucleus but are neither animal, plant nor fungus.
[1 mark]Which set of features identifies a vertebrate as a mammal?
Arthropods are divided into four main groups: insects, arachnids, crustaceans and myriapods.
Complete the table by stating the number of body sections and the number of pairs of legs for each group. Group: number of body sections / pairs of legs. (1) Insect: ___ / ___ (2) Arachnid: ___ / ___ (3) Crustacean: typically more than 5 / typically more than 5
[3 marks]A student uses a dichotomous key to identify an unknown organism. The key works by:
An unknown plant species has the following features: it produces seeds (not spores), the seeds are enclosed inside a fruit, it has flowers with petals, and its leaves have a network of veins (not parallel veins).
Identify the major group within plants to which this species belongs, and justify with TWO features from the description.
[3 marks]Network (net) veins in the leaves suggest the plant is a dicotyledon (dicot) rather than a monocotyledon. State ONE other feature you would expect a dicot to show.
[1 mark]Viruses contain genetic material (DNA or RNA) inside a protein coat. Suggest TWO reasons why viruses are NOT placed in any of the five kingdoms.
[2 marks]When making a dichotomous key for a set of organisms, which pair of statements is the BEST choice for an early step?
