Question

Which among the following statements define omega taxonomy?
A. It involves the description and naming of organisms.
B. It involves morphological description only.
C. It is based on information from branches such as cytology, embryology, etc. in addition to morphology and phylogenetic characters.
D. None of the above.

Answer 1

Hint: In omega taxonomy, the taxonomic studies are made more relevant by considering and including the data collected from various fields of biology and also involving adequate computation.

Complete answer:
Omega taxonomy is one of the types of taxonomy and is considered to have the widest scope as compared to the other types because it is based on all the information that is available about plants like embryology, cytology, ecology, cytogenetic, phytochemistry, phylogeny, morphology, etc. and also includes adequate computation to arrange and classify the plants according to the considered features. Since all the information available about the plant is considered in the omega taxonomy, in the taxonomic studies it serves as an encyclopedia for the plants being studied and thus also known as encyclopaedic taxonomy.

Additional information
Taxonomy is a branch of science that includes activities like naming, describing, and then classifying the living organisms according to similarity and dissimilarity between them in various aspects. The types of taxonomy have been given below –
- Alpha taxonomy or classical taxonomy
- Beta taxonomy or explorative taxonomy
- Omega taxonomy or encyclopedic taxonomy
- Chemotaxonomy
- Cytotaxonomy

So, the correct answer is ‘It is based on information from branches such as cytology, embryology, etc. in addition to morphology and phylogenetic characters’.

Note: Those methods of classifications or taxonomy are considered better that include a broad range of features of living organisms like external, internal, and also phylogenetic. Alpha and beta taxonomy found less scope as compared to omega taxonomy because the former considered only external morphology while the later included external and internal features but left phylogenetic characters.
