Types of Classification

Q.

Give one advantage and one disadvantage of natural system of classification.

Q. Which of the following is/are the objective(s) of classification:

1. Identification and description of organisms
2. Arrangement of organisms in various categories
3. All of the above
4. Establishing a phylogenetic system indicating origin & evolution of the species.
   

Q. All the categories together in a taxonomic arrangement constitute

1. taxonomical aids
2. zoological hierarchy
3. taxonomical hierarchy
4. none of the above

Q.

Who discovered taxonomy?

Q.

The plant classification proposed by Bentham and Hooker is a /an

1. Artificial system

2. Natural system

3. Phylogenetic system

4. Numerical system

Q. The scientist who gave the binomial nomenclature is also credited with

1. natural system of classification
2. artificial system of classification
3. phylogenetic system of classification
4. chemotaxonomy

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. Numerical taxonomy: Every character is given equal importance
4. Phylogenetic system of classification: Bentham and Hooker

Q. Choose the incorrect statement on the natural system of classification:

1. Plant Kingdom is divided into cryptogams and phanerogams
2. Phanerogams are further divided into gymnosperms, dicotyledons and monocotyledons
3. Cotyledons are the very first leaves that appear from a germinating seed
4. Cryptogams are flowering plants and phanerogams are non-flowering plants

Q. Natural system of classification includes the study of:
I. Reproductive structures
II. Height and girth of the plant
III. Ultrastructure and anatomy
IV. Embryology and phytochemistry

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

Q.

Mention the different types of classification.

Q. Which of the following classification system is based entirely on the vegetative properties and the androecium structure of a plant?

1. Artificial
2. Natural
3. Phylogenetic
4. Bentham and Hooker's

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

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

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

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

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

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

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. Numerical taxonomy: Every character is given equal importance
4. Phylogenetic system of classification: Bentham and Hooker

Q. Choose the option with correct statements about the reason for further classification of Kingdom Plantae:
I. Convenient to place new organisms
II. Categorization allows ease in categorizing newly discovered organisms
III. Sort the huge diversity of organisms
IV. A dump of organisms looks ugly and classification is presentable

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