Tag: taxonomy and systematic botany

Taxonomy is the study of science concerned with classification according to their natural relationships. Carl Linnaeus is regarded as the father of taxonomy as he developed a system for categorization of organisms and binomial nomenclature for naming organisms. But Taxonomy's first father was the philosopher Aristotle, he first introduced the two key concepts of taxonomy: classification of organisms by type and binomial definition. Therefore founder of taxonomy is Aristotle. Hence option A is correct.

Taxonomy is a branch of biological science involved with classifying organisms based on characteristics they share in common. Using morphological, behavioural, genetic and biochemical observations, taxonomists identify, describe and arrange species into a hierarchical system of groups.

Peritrichous flagellation means containing flagella projecting in all directions.

Gingko is a living fossil. Newly found specimens that grew more than a hundred million years ago. It is remarkably similar to present-day plants.

Selaginella possesses a rhizophore which is a prop like structure that originates at a point of branching.

The flower of Wolffia is famous as the smallest flower in the world. It has one stamen and one pistil.

Macrocystis, kelp is the largest of all algae. The stage of the life cycle commonly can be seen, is the sporophyte, which is perennial and individuals persist for many years.

Therefore the correct option is A

Hence option A is correct.

• Taxonomy can be analyzed on a measuring scale based on OTU (Operational taxonomic unit), Carbon dating and Karyotyping.
  
• An operational taxonomic unit (OTU) is an operational definition used to classify groups of closely related individuals.
  
• Carbon dating is used to determine age of age old fossils.
• Karyotyping is arranging and pairing of different chromosomes of an organism. They can be compared to study inter-relationship and evolutionary connection between organisms in a taxon. 

A plant which lives for a few days is called ephemral because of a very short growing season.  Such plant are found near desert or in very cold  countries e.g., Arabidopsis species  have life span of  20-28 days . 

• The International code of botanical nomenclature (ICBN) is the organization that is responsible for rules and recommendations which are proposed whenever organisms are named. 
• There were different codes that were put forward in the years of 1800 and 1900s. 
• The final revised code for ICBN was revised and accepted in the year 1978. 

It absorbs only blue and yellow green light and becomes inactive for the photomorphogenesis, photoperiodism etc.

Amorphophallus (or simple spadix inflorescence) is the largest inflorescence with 5.5 m length. Amorphophallus inflorescences variety in size from small, to the largest unbranched inflorescence in the world. This is the Amorphophallus titanium. It is found in the jungles of Sumatra. Whereas the remaining three are not in this category of the inflorescence.

The correct option is C.

Maize is a monocotyledonous plant where as China  rose, Mango and sunflower are dicotyledonous plants.
