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

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

  1. Animalia

  2. Plantae

  3. Fungi

  4. Protista

Show answer
Correct Option: B
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'.

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

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

  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

Show answer
Correct Option: C
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'

Binomial system of nomenclature means that every organism has___________

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

  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

Show answer
Correct Option: C
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.

Who proposed the 'Binomial Nomenclature System'?

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

  1. Whittaker

  2. Mendel

  3. Carl Linnaeus

  4. Tippo

Show answer
Correct Option: C
Explanation:

The binomial system of nomenclature was introduced by Carolus Linnaeus. In this system, he gave scientific names to plants and organisms in which the first part is 'genus' and the second part is 'species'.

Organisms in kingdom Plantae have cell wall made up of__________

biology plant taxonomy nomenclature in classification introduction to plant kingdom history of classification

  1. Lipid

  2. Cellulose

  3. Glucose

  4. Chitin

Show answer
Correct Option: B
Explanation:

  • Cell wall is the outermost covering/membrane of organisms belonging to the kingdom Plantae. Their cell wall is made up of cellulose which is a form of sugar.
Therefore, the correct answer is option B.

Match the following.

Column (A) Column (B)
a. Kingdom (i) Pteridophyta
b. Subkingdom (ii) Plantae
c. Division (iii) Cryptogams
biology plant taxonomy nomenclature in classification introduction to plant kingdom history of classification

  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

Show answer
Correct Option: C
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 

biology plant taxonomy nomenclature in classification introduction to plant kingdom history of classification

  1. Heterotrophs

  2. Photoautotrophs

  3. Symbionts

  4. Parasites

  5. Herbivores

Show answer
Correct Option: B
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'.

Bentham and Hooker's system of classification is based on

botany plant taxonomy nomenclature in classification introduction to plant kingdom history of classification

  1. AP de Candolle's system

  2. Engler and Prantl system

  3. Eichler system

  4. Wilkins system

Show answer
Correct Option: A
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.'

P: The taxonomic hierarchy for Brassica campestris can be written as.
Plantae $\rightarrow$ Phanerogamae $\rightarrow$ Angiospermae $\rightarrow$ Dicotyledonae $\rightarrow$ Parietales $\rightarrow$ Brassicaceae $\rightarrow$ Brassica $\rightarrow$ campestris.
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.
Which of the following combinations of given statements is correct?

botany plant taxonomy nomenclature in classification introduction to plant kingdom history of classification

  1. P and Q

  2. P and R

  3. R and S

  4. P, R and S

Show answer
Correct Option: B
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

botany taxonomy and systematic botany taxonomy and systematics systematics of living world kingdom plantae plant taxonomy classification of biodiversity

  1. One or very few characters

  2. Phylogenetic trends

  3. Many naturally existing characters

  4. None of the above

Show answer
Correct Option: A
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.
