Q. No.George Bentham and Joseph Hooker gave the classification based on
1. Artificial system
2. Natural system
3. Phlogenetics
4. Numerical system
1. Artificial system
2. Natural system
3. Phlogenetics
4. Numerical system
Under natural system of classification which of the following character is not considered?
(1) External features
(2) Phylogeny
(3) Anatomy, Embryology
(4) Phytochemistry
Phylogenetic classification systems based on
| 1. | Evolutionary relationships between the various organism |
| 2. | Organisms belonging to the same taxa may have a different ancestor |
| 3. | Both A and B |
| 4. | Based on cytological information like chromosome number, structure, behavior. |
If we want to know evolutionary relationships between organisms then which classification will resolve it :
(1) Artificial classification
(2) Natural classification
(3) Cytotaxonomy
(4) Phylogenetic classification
Numerical Taxonomy
| 1. | Carried out using computers |
| 2. | Based on all observable characteristics |
| 3. | Number and codes are assigned to all the characters |
| 4. | All of these |
Cytotaxonomy
(1) Based on cytological information like chromosome number
(2) Based on cytological information like chromosome structure
(3) Based on cytological information like chromosome behavior
(4) All of these
Chemotaxonomy
(1) Chemical constituents of the plant
(2) Cell structure
(3) Phylogeny
(4) Embryology
Algae is not
| 1. | Chlorophyll-bearing |
| 2. | Simple Thalloid |
| 3. | Mainly Fresh water |
| 4. | Largely Aquatic |
Algae may occur
| 1. | Moist Stones |
| 2. | Moist Soils and moist wood |
| 3. | Occur in association with fungi |
| 4. | All of these |
