Question 9

Mention any two drawbacks in classifying organisms under the old two kingdom classification.

Answer

Carolus Linnaeus In 1758, anciently divided all living organisms into two kingdoms : The drawbacks of this classification are:

  1. Bacteria were kept in Kingdom Plantae. These organisms have no chlorophyll and do not carry out photosynthesis. Bacteria do not have a definite nucleus nor a nuclear membrane nor chromosomes.
  2. Fungi were kept in Kingdom Plantae. Bread mould is a multicellular fungi. However, it does not possess roots, stem and leaves, lacks chlorophyll and does bear any flowers, fruits and seeds like plants.
