Principles of classification questions | form five Biology

Giving one example in each case, describe the main features that are used to place organisms into each of the following groups:-

Protozoa, Arthropoda,Aschilminthes, Monocotyledonae and Dicotyledonae.

1. Classify the following organisms to the class level.
   (i) Bean
   (ii) Crab
   (iii) Elephant grass
   (iv) Mouse.
2. Giving six reasons, justify the:
   (i) Phylum to which mouse belongs.
   (ii) Class to which bean plant belongs.

1. Study Figure 1 and answer questions which follow.

(i) Name the organism.
(ii) Classify the organism to division level.
(iii) Explain four general and three distinctive feature of the kingdom to which the organism belongs.

2. (i) Identify the parts labeled U, V, W, X, Y and Z.
   (ii) State three roles played by the part labeled Y.
   (iii) Give five ways in which the organism structurally adapts to its mode of life.

1. What is meant by natural system of classification?
2. Why is it difficult to achieve a complete natural system of classification?

(i) What is the scientific name of human being?
(ii) List hierarchically the major classification taxa.

(i)Why are Animal, Plant, Protoctista and Fungi considered to be Eukaryote Kingdoms while bacteria are considered to be Kingdom Prokaryotae?
(ii) State five rules that a biologist should follow in binomial nomenclature.

1. Identify the lowest taxon
2. Illustrate the taxonomic hierarchy of human being.

1. Why classification of organisms is needed? Give three points.
2. Analyze three differences between natural and artificial systems of classification.

1. Define the term taxonomic hierarchy
2. Using man as an example, illustrate the concept of taxonomic hierarchy.

Explain four advantages of using artificial system of classification.
