Questions with solutions
Q1 — Classification Systems · easy · theory
Artificial systems of classification were based mainly on:
A. Chemical constituents
B. Evolutionary relationships
C. One or a few vegetative/floral characters (e.g. Linnaeus used stamens) ✓ Correct
D. Chromosome number
Solution: Artificial systems used one or a few easily observed characters and gave equal weight to vegetative and sexual features.
Q2 — Classification Systems · easy · theory
Phylogenetic classification systems are based on:
A. Evolutionary relationships among organisms ✓ Correct
B. Habitat alone
C. Only floral characters
D. Only economic uses
Solution: Phylogenetic systems assume organisms of the same taxon share a common ancestor.
Q3 — Classification Systems · medium · theory
Natural classification systems (e.g. Bentham & Hooker) differ from artificial ones because they:
A. Use only the number of stamens
B. Use overall (many) natural characters, including internal features ✓ Correct
C. Are based only on DNA
D. Ignore all morphology
Solution: Natural systems consider many characters and natural affinities, unlike the one-character artificial systems.
Q4 — Classification Systems · medium · theory
Numerical taxonomy assigns:
A. No numerical codes
B. Equal weightage to all characters, processed by computers ✓ Correct
C. Importance only to habitat
D. Weightage only to floral parts
Solution: Numerical taxonomy codes hundreds of characters, giving each equal weight, and processes them numerically.
Q5 — Classification Systems · hard · theory
Cytotaxonomy and chemotaxonomy are modern aids that use, respectively:
A. Cytological information (e.g. chromosome number/behaviour) and chemical constituents ✓ Correct
B. Numerical codes only
C. Fossils and habitats
D. Only external morphology
Solution: Cytotaxonomy uses chromosome data; chemotaxonomy uses chemical constituents to resolve confusions.
Q6 — Classification Systems · hard · theory
Bentham and Hooker's classification, though natural, is criticised because it placed gymnosperms:
A. Before algae
B. Between dicots and monocots (an unnatural position) ✓ Correct
C. Within the angiosperms as a family
D. After the animals
Solution: In Bentham & Hooker's scheme gymnosperms were placed between dicotyledons and monocotyledons, now considered incorrect.
