Question

Carolus Linnaeus classified plant kingdom on the basis of
A. Floral morphology
B. Overall morphology of plant
C. Type of sexual reproduction
D. Anatomical character

Answer 1

Hint:- Systematic taxonomy refers to both theoretical and practical characters used by biologists to classify living beings. Its usability lies behind the need for separating the huge variety of living organisms found all over the natural world: from massive-sized whales to the tiniest of bacteria.

Complete Answer:-
Carl's Linnaeus is regarded as the father of taxonomy. He discovered 24 classes of angiosperm plants or flowering plants based on the stamen's numbers and their connate state. He categorized these classes into orders on the basis of characteristics of carpel.
As per the above discussion the correct option of given question is option A, Floral morphology.

Additional Information:-
Linnaeus classified nature into hierarchy. He proposed three broad groups called Kingdoms, these three kingdoms were; animals, plants, and minerals. He further divided these kingdoms into classes, classes into orders, and this is further divided into genera and then species. This system is still used but some changes have been made.
Nowadays, we are using this system but non-living minerals are deleted from classification. We have added a few other kingdoms, monera, prostita, and fungi with plants and animals. All the living organisms fit into three domains: archaea, Bacteria and eukarya. Eukarya contain; prostita, fungi, plantae and animalia. Each kingdom contains phylum, followed by class, order, family, genus and species.

Note:- All over the biologist set two international codes which follow all the protocols of the naming system. They are ICBN and ICZN. ICBN – International Code of Botanical Nomenclature, which deals with the biological nomenclature for plants. ICZN – International Code of Zoological Nomenclature deals with the biological nomenclature of animals.
