Taxon is a scientific term used for different categories of classification. Taxonomic hierarchy is position of different taxonomic categories is ascending order, which describes the complete systematic position of any living organism. Given below is the flow diagram of taxonomic hierarchy

Taxon	Plant	Animal
Kingdom This is the highest category of classification, which includes all organism that share a set of distinguishing common characters. Phylum/Division It includes different classes having a few common characters.	Kingdom-Plantae Division is used in plants.	e.g., kingdom-Animalia. Phylum is used in animals e.g., Chordata includes classes like Pisces, Amphibia, Reptilia, Aves and Mammalia.
Class Represents organisms of related orders. Order It is an assemblage of families resembling one another in few characters. These characters are less similar as compared to characters of many genera placed in a family. Family It includes one or more genera differentiated from others related families by certain characteristic differences (both vegetative and reproductive).	Found only in flowering plants, i.e., Monocotyledoneae and dicotyledoneae. e.g., dicotyledoneae consists of order rosales polemoniales, sapindales, ranales etc. on the basis of floral characters. e.g., Order Polemoniales comprises families like Solanaceae and Convolvulaceae	Comprises of related orders i.e., classMammalia e.g., class-Mammalia includes order chiroptera, marsupialia, rodentia, cetacea, carnivora. e.g., order carnivore include families like Felidae (cats), canidae (dogs, foxes), ursidae (bears) etc.
Genus It is the first higher category above the species level. It is a group of species, which are related and have fever characters in common as compared to species. Species It is a group of individuals with similar morphological characters, which are able to interbreed and produce individuals of their own kind.	e.g., Family-Solanaceae comprises of genus Solanum. e.g., Solanum nigrum (brinjal) and Solanum tuberosum. Here nigrum and tuberosum are two species of Solanum genus.	e.g., hlidae comprises of genus Panthera (lion, tiger) and Felis (cats) e.g., The genus Panthera includes species leo (lion) and Panthera tigris (tiger).

As we move up in the taxonomic hierarchy the number of shared characters become less.

Identification of a plant is a scientific process. One has to study the general morphological characters along with its habitat, place of collection, time of flowering, etc., for identification. Several reference materials are available in the form of taxonomic keys. Professor meant to refer to these keys to help the student to identify the plant. This concept of key was introduced by Ray. Separate taxonomic keys are required for each taxonomic category. Keys are analytical in nature and are used as reference to help in identification of a newly discovered plant.

Metabolism is the sum of all synthesing (anabolic) and breaking down (catabolic) reactions. These are highly specific and enzymatically controlled reactions, which take place inside all the individual cells of unicellular or multicellular organisms.

These are infact the basis of life. These reactions help organism to grow, reproduce, maintain their steady state and respond to stimuli. It can be understood by taking example of digestion.

All organisms need nutrition in the form of food, which is digested by metabolic reactions either intracellularly or extracellularly depending upon the type of organisms. So, all reactions which help the organisms to breakdown food molecules and then assimilate them for their growth and reproduction are metabolic reactions.

Few reactions may be performed outside the cells, under controlled conditions, Chemical reactions usually involve specific set of conditions to take place. All biological reactions are highly specific, selective and are enzyme catalysed.

Consciousness is a defining property of all living organisms. Whereas coma is profound or deep state of unconsciousness lasting more than six hours, in which person can not be awakened, fails to respond normally to painful stimuli, light or sound. Such person exhibit complete absence of awakefulness and unable to consciously feel, speak, hear or move. Such person is brain dead and we consider such person as living dead.

The similarity and dissimilarity between whole moong daal and broken moong daal is as follows

S.N.	Whole Moong Daal	Broken Moong Daal
1.	Whole moong dal is a intact seed of a plant.	It is not intact seed.
2.	When given all suitable conditions for germination, it germinates.	Unable to germinate as vital seed part such as embryo and cotyledons are destroyed.
3.	During germination, it resumes metabolic activity.	Unable to resume metabolic activity.
4.	Due to metabolism activated enzymes hydrolyse stored food in the cotyledons.	Broken seed will imbibe water, enzyme will get activated but will not lead to growth.
5.	Uses oxygen and respire as a result emits $\mathrm{CO}_2$.	Because of destruction of embryo, no respiration, so no $\mathrm{CO}_2$ emission.
6.	As seed resumes active metabolism the embryo givens rise to plumule (shoot) and radicle (root).	No such growth seen, but broken daal has nurishment value for human as its cotyledons have stored food material rich in protein.

So, we can conclude that broken moong daal does not have viable embryo so does not germinate and does not show any metabolism and growth, but it has great nutritive value as it has good amount of protein and minerals.
