Tools that Aid Phylogenetic System Of Classification

Q.

What is a cladistics?

Q. Choose the correct combination:

1. Linnaean system of classification: Height and girth of the plant
2. Natural system of classification: Edible plants, poisonous plants and medicinal plants
3. Phylogenetic system of classification: Bentham and Hooker
4. Numerical taxonomy: Every character is given equal importance

Q. Cytotaxonomy includes the study of:
I. Chromosome number
II. Number of observable characteristics
III. Chromosomal behaviour
IV. Chromosome morphology

1. Only I and II
2. Only I, III and IV
3. Only I, II and IV
4. Only II and III

Q. Classification based on features like chromosome number, structure and behaviour is called

1. chemotaxonomy
2. cytotaxonomy
3. phylogeny
4. numerical taxonomy

Q.

Classification based on chromosome number, structure and behaviour is called

1. Chromotaxonomy

2. Cytotaxonomy

3. Chemotaxonomy

4. Numerical taxonomy

Q. Classification done on the basis of cytological information, chromosome structure and their behaviour, is known as:

1. Cytotaxonomy
2. Karyotaxonomy
3. Chemotaxonomy
4. Molecular classification

Q. Choose the incorrect statement about numerical taxonomy.

1. It takes into account all observable characteristics
2. Hundreds of characters can be considered at a time
3. Cannot be carried out using softwares
4. Each character is given equal weightage

Q. When fossils are not available for the construction of phylogenetic tree, the classification is done using

1. chemotaxonomy
2. cytotaxonomy
3. all of the above
4. numerical taxonomy

Q. Classification done on the basis of cytological information, chromosome structure and their behaviour, is known as:

1. Cytotaxonomy
2. Molecular classification
3. Chemotaxonomy
4. Karyotaxonomy

Q. Classification based on features like chromosome number, structure and behaviour is called

Q. Chemotaxonomy is based on

1. chemical constituents
2. morphology
3. arrangement of stamen
4. evolutionary relationship
