Q. No.
In the following diagram A, B, C and D represent
1. A - Seta, B - Leaves, C- Rhizoids, D - Capsule
2. A - Leaf, B - Rhizoids, C- Scales, D - Root hair
3. A - Capsule, B - Seta, C- Leaves, D - Rhizoids
4. A - Capsule, B - Foot, C- Leaves, D - Rhizoids
The incorrect match for chlorophyll type is
1. Chlorophyll ‘a’ .... Green algae
2. Chlorophyll ‘d’ ... Diatoms
3. Chlorophyll ‘c’ ... Dinoflagellates and Brown algae
4. Chlorophyll ‘d’ ...Red algae
What is the artificial basis of classification?
(1) It is based on vegetative characters only
(2) It is based on few vegetative and reproductive characters
(3) It is based on only reproductive characters
(4) It is based on any random classification
Why are reproductive characters given more weightage during advanced classification?
| 1. | Vegetative characters are more or less constant over the generation |
| 2. | Reproductive characters are less constant over the generation |
| 3. | Vegetative characters are easy to get affected by environment |
| 4. | Reproductive characters are more or less constant over the generation |
George Bentham and Joseph Hooker gave the classification based on
(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
If we want to know evolutionary relationships between organisms then which classification will resolve it :
| 1. | Artificial classification |
| 2. | Natural classification |
| 3. | Cytotaxonomy |
| 4. | Phyogenetic classification |
In numerical taxonomy
(1) All the characters are given equal importance
(2) All the characters are given unequal importance
(3) And at the same time, hundreds of characters can be considered
(4) Both A and C
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 |
