Multiple choice biology plant taxonomy classification of kingdom plantae features of plant and animal kingdom plant classification

Choose the correct answers from the alternatives given.
Into which of the following kingdoms would you place a multicellular land organism that carries on photosynthesis

  1. Animalia

  2. Plantae

  3. Fungi

  4. Protista
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Kingdom Plantae includes all eukaryotic chlorophyllous autotrophic organisms. A few members are partially heterotrophic such as insectivorous plant or parasites. bladderwort and venus fly trap are examples of insectivorous plants and Cuscuta is a parasite. 

Hence, the correct answer is 'Plantae'.

Multiple choice biology plant taxonomy classification of kingdom plantae features of plant and animal kingdom plant classification

Choose the correct answers from the alternatives given.
Plants are believed to have evolved from the

  1. euglenophytes, because they have chlorophyll a and b

  2. dinoflagellates, because they have similar storage products and cellulosic cell walls

  3. chlorophytes, because of similarities in chloroplasts and accessory pigments

  4. rhodophytes, because they have carotenoids and use floridean starch as a storage product
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Chlorophyta is the green algae that contain the pigment chlorophyll A and chlorophyll b in the well-defined chloroplast. Plants are considered to have evolved from Chlorophyta because plants are green in color and they have chlorophyll A and chlorophyll b pigment just like the Chlorophyta family.

There is well-defined chloroplast which stores this pigment in plants.
So, the correct option is 'chlorophytes, because of similarities in chloroplasts and accessory pigments'

Multiple choice zoology plant taxonomy nomenclature in classification nomenclature of animals introduction to plant kingdom

Binomial system of nomenclature means that every organism has___________

  1. Two names, one scientific and the other popular

  2. One name given by two scientists

  3. One scientific name consisting of a generic and specific name

  4. A number in an international catalogue by which it can be identified
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
 C Linnaeus, the father of taxonomy, introduced the binomial system of nomenclature. He dealt about this in the 10th edition of his book 'Systema Naturae' which was published in 1785.
This is a system of providing organisms with distinct scientific names which consist of two words, the first one indicating a generic name (Genus). The first and second together form a specific name (Species). These two words are in Latin or Latinized if derived from other languages.
Genus is a common noun and starts with a capital letter. It indicates the name of a group. In the specific name, the second word is like an adjective and begins with a small letter excepting the cases when it denotes proper nouns like the name of a person, place or the like. It may then, start with a capital letter.
The names when written should be underlined to indicate their Latin origin. In the printed form, they should be italicized.
The name of the author who has first described the plant in scientific journals may be appended in full or abbreviated form. For example - the botanical name of mango is Mangifera indica Linn. All three comprise binomial nomenclature.
The generic name is one for all species whereas the species name is variable. For example - Ficus bengalensis, Ficus religiosa, Ficus glomerata, which represent banyan, peepul and fig trees respectively. All have one generic name Ficus but their species names are F.bengalensis, F.religiosa, F.glomerata.

b. Subkingdom (ii) Plantae
c. Division (iii) Cryptogams

  1. a- i, b- ii, c- iii

  2. a- iii, b- i, c- ii

  3. a- ii, b- iii, c- i

  4. a- ii, b- i, c- iii
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Plantae is a kingdom, cryptogams is a subkingdom of planate. They include all non-flowering plants. Pteridophyta is a division of subkingdom cryptogams.

Therefore, the correct answer is option C.

  Organisms such as  plants that use light to make their own food are known as 

  1. Heterotrophs

  2. Photoautotrophs

  3. Symbionts

  4. Parasites

  5. Herbivores
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
A. Heterotrophs are the organisms that feed on autotrophs or producers for their food.
B. Photoautotrophs are the organisms that use the light energy and convert it into chemical energy to make their food. For example, plants.
C. Symbionts are the organisms that form association with other organisms. The association may be commensalism, mutualism, parasitic etc.
D. Parasites are the organisms that live within or on an other organism which is called the host.
E. Herbivores are the primary consumers that feed directly on the producers (plants).
Hence organisms such as plants that use light to make their own food are known as photoautotrophs.
So, the correct answer is 'Photoautotrophs'.
Multiple choice botany plant taxonomy nomenclature in classification introduction to plant kingdom history of classification

Bentham and Hooker's system of classification is based on

  1. AP de Candolle's system

  2. Engler and Prantl system

  3. Eichler system

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

Bentham and Hooker's system of classification is the natural system of clarification. It is based on AP de Candolle's system. AP de Candolle gave a new system of classification of plants based on characteristics of vascular tissues much before Bentham and Hooker's system. 

Thus, the correct answer is 'AP de Candolle's system.'

Q: Tautonym is the taxonomic designation used for certain plants having trinomial nomenclature.
R: A character present in an ancestral species and shares exclusively by its evolutionary descendants is referred to as synapomorphy.
S: Family Fabaceae is divided into three sub-families, i.e., Leguminosae, Mimosaceae and Caesalpiniaceae.

B Correct answer
Explanation

Tautonym is the taxonomic designation used for certain animals assigned with same generic name and specific name. E.g. Rattus rattus (rat), Catla catla (catla), etc. Family Leguminosae is divided into three sub-families, i.e., Papilionacea ($=$Fabaceae), Mimosaceae and Caesalpiniaceae.

Artificial system of classification classifies plants on the basis of

  1. One or very few characters

  2. Phylogenetic trends

  3. Many naturally existing characters

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The major advantage of the artificial system of the classification is considering one or few characters of the plants, so the option (A) is the correct answer.
The phylogenetic trends consideration are all comes under the natural classification, so the option (B) is not the correct answer.
The option (C) refers, many naturally existing characters, which is suitable for the natural classification, not for artificial classification, so the option (C) is also not the correct answer.
