Question

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

Answer 1

According to the 'Two-Kingdom Classification', proposed by Carolus Linnaeus in 1758, living organisms were classified into two broad kingdoms, Plants and Animals.

The drawbacks in classifying organisms under the old two-kingdom 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.
