Identify the incorrect statement:
1. | The earliest systems of classification used only gross superficial morphological characters. |
2. | Linnaeus classification of plants was a natural classification as it was based on the androecium structure. |
3. | Artificial systems gave equal weightage to vegetative and sexual characteristics. |
4. | Natural classification systems are based on natural affinities among the organisms |
Who proposed a five-kingdom classification and named kingdoms as Monera, Protista, Fungi, Plantae and Animalia?
1. Herbert Copeland
2. RH Whittaker
3. Carl Woese
4. Carolus Linnaeus
Artificial systems gave equal weightage to
1. Morphological and anatomical characters.
2. Vegetative and sexual characters.
3. Vegetative and anatomical characters.
4. Morphological and sexual characters.
Which of the following kingdoms is not introduced in the Whittaker's classification?
1. Monera
2. Protista
3. Gymnosperms
4. Fungi
Earlier classification (Before Whittaker) has placed which of the following in the same kingdom Plantae and now they are no more considered under plants?
1. | Monera, Protista and Fungi |
2. | Monera and Protista |
3. | Animals, Protista, Fungi |
4. | Fungi and Monera, Animalia |
Blue Green algae comes under
1. | Monera | 2. | Brown Algae |
3. | Eukaryotes | 4. | Plantae |
The earliest system of classification does not include which of the following features?
1. | Habit, color, number and shape of leaves |
2. | Gross morphology, androecium structure |
3. | Vegetative structure |
4. | Phytochemistry |
The classification given by Linnaeus was depending on
1. Phytochemistry
2. Embryology
3. Structure of androecium
4. Anatomy
The main reason of failure of artificial classification was
1. | It considered only vegetative characters |
2. | It gave more weightage to vegetative characters |
3. | It gave more weightage to reproductive characters |
4. | It gave equal weightage to both vegetative and reproductive characters |
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
