A Correct answer
Explanation

Agave and Yucca were moved to Agavaceae primarily due to their anatomical similarities, specifically in their vascular structure and leaf morphology.

Which one of the following is the correct statement about the respective animal(s)? 

  1. Donkey and horse should be considered one single species because they can successfully mate and produce an offspring.

  2. Donkey and horse are two different genuses.

  3. Mule is a separate species.

  4. Mule is neither a donkey nor a horse.

D Correct answer
Explanation

A mule is the sterile offspring of a male donkey and a female horse. It is not a separate species because it cannot reproduce with other mules to maintain a population.

The highest category in taxonomy is 

  1. Phylum

  2. Class

  3. Kingdom

  4. Species
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • According to the taxonomical hierarchy, the kingdom is the highest category in biological classification. It is a group of closely related organisms. 
  • Kingdom → Phylum → Class → Order → Family → Genus → Species.
  • Example: All plants have common features of the autotrophic mode of nutrition and the presence of a cell wall made up of cellulose. Hence, they belong to the kingdom Plantae.
So, the correct option is 'Kingdom'.

Which of the following scientist created the group Protista for both unicellular plants and animals?

  1. Haeckel

  2. Pasteur

  3. Lister

  4. Koch
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In the year 1866, Ernst Haeckel proposed the three kingdom classification. The three kingdoms are protista, plantae and animalia. The unicellular prokaryotic organisms were placed in the group of monera. This group includes the organisms which have chloroplast and resemble plants as well as the organisms which resemble animals. The group of protists are divided into two groups as plant-like protists and animal-like protists. 

Thus, the correct answer is option A.

Choose the correct answers from the alternatives given.
The system of plant classification proposed by Carolus Linnaeus was artificial because:

  1. he was not a naturalist

  2. his classification was based on similarities and differences in floral and other morphological characters only

  3. his classification was based on evolutionary relationships

  4. he took into account the physiological relationships along with morphological observations
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Linnaeus's system was artificial because it relied on a few easily observable morphological characters, such as the number of stamens, rather than evolutionary or phylogenetic relationships.

Multicellular eukaryotic organism with holophytic mode of nutrition belong to how many kingdoms in Whittaker system?

  1. One

  2. Two

  3. Three

  4. Five
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In Whittaker's five kingdom system of classification, only kingdom Plantae have organisms with a multicellular eukaryotic organism with holophytic nutrition. The organisms which are able to synthesize food by photosynthesis are said to have holophytic nutrition. 


So, the correct option is ' one'.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The two kingdom classification system was given by Carlous Linnaeus in 1758, who classified living things into two kingdoms: Animal Kingdom (mobile and heterotrophic) and Plant Kingdom (fixed, stationary in the soil, autotrophic). These were then divided into classes and the classes into phyla for animals and divisions for plants. R.H Whittaker proposed the five kingdom classification in 1969, in which all living organisms are divided into five kingdoms based on their complexity of cell structure, complexity of organism’s body and mode of nutrition. The five kingdoms are Monera (prokaryotic BGA and bacteria), Protista (Eukaryotic unicellular organisms; algae and protozoa), Fungi, Plantae and Animalia. The four kingdom classification concept was given by Haeckel who divided living organisms into four kingdoms namely Monera, Protista, Metaphyta and Animalia. BGA and bacteria differ in their kind or reserve food, mode of nutrition, movement and type of photosynthetic pigments. Thus, the correct answer is option C.
