Diversity in Living World

Introduction 

Understanding the diversity in the living world from the perspective of taxonomy is important to understand the classification, properties, features, attributes of the living organisms on the planet. The concept of diversity in the living world is helpful for better understanding organisms and their life processes. 

Biological Classification

All living organisms are broadly categorised into the following five kingdoms:

Kingdom Monera

The kingdom monera consists of multiple topics like bacteria, prokaryotic organisation of the cells, various forms of nutrition found in bacterias, their types, their forms, etc. Archaebacteria is also an important part of this kingdom and some other topics like eubacteria, cyanobacteria, as well as mycoplasma. Moreover, it has prokaryotic cellular organisation under the cell structure and function.

Kingdom Protista

In this kingdom, you will get to learn the eukaryotic cellular organisation as well as chrysophytes, dinoflagellates, euglenoids, slime moulds, and protozoans at the same time.

Kingdom Fungi

In this kingdom, there are various types and modes of nutrition of the ubiquitous fungal forms as well as their mode of reproduction in multiple methods. It will also tell you about the classes of the kingdom fungi depending on their hyphae, fruiting bodies, as well as reproduction.

Kingdom Plantae

Plant kingdom comes on number four under the 5-Kingdom classification scheme introduced by Whittaker. In this kingdom, you will get to know the organisms with the autotrophic mode of nutrition with some rare and exceptional plants that comprise the heterotrophic mode of nutrition. The following topics are discussed under the kingdom of plants:

Thallophyta – here, you will learn about the algae and their several forms.

Bryophyta – here, you will get to know about the plants that are said to be the amphibians of the kingdom of plants.

Pteridophyta – here, you will read about the first terrestrial plants that developed vital terrestrial features, most importantly the vascular tissues.

Gymnosperms – under this topic you will learn about the plants that controlled our planet during the Jurassic period. They do not create flowers, however, they give naked seeds.

Angiosperms – It has the successful plants of the present time. These are the plants that produce flowers. However, under the angiosperms, there is a brief on their morphology, reproduction, and anatomy at the same time.

Animal Kingdom

It is the last one in the 5-Kingdom classification scheme given by Whittaker. There are various fascinating animals in the animal kingdom. Moreover, you will get to know the process of organising the multiple body forms of the animals as well as their body symmetries, notochord, coelom, etc. In addition, on the basis of the notochord, the kingdom of animals is divided into 2 wide categories that are Vertebrates and in-vertebrata. Here are the phylum(s):

Phylum Porifera – tells about the primitive and simple animals known as Sponges.

Phylum Coelenterata – tells about the aquatic, marine, sessile, swimming, or animals that are radially symmetrical.

Phylum Ctenophora – tells about the sea walnuts as well as the comb jellies that are absolutely marine and radially symmetrical at the same time.

Phylum Platyhelminthes – talks about the flatworms that are majorly endoparasites present in animals as well in human beings.

Phylum Aschelminthes – it has roundworms that are possibly free-living, aquatic as well as terrestrial or parasitic in animals and plants at the same time.

Phylum Annelida – it has marine and freshwater or we can say aquatic as well as terrestrial, free-living, and parasitic animals.

Phylum Arthropoda – it is the biggest phylum of the Kingdom Animalia which comprises insects. 

Phylum Mollusca – it is the 2nd largest phylum of the Kingdom Animalia and it has animals with soft bodies.

Phylum Echinodermata – it is said to be the advanced phylum having starfishes, brittle stars, and many other fishes like them.

Phylum Hemichordata – this phylum deals with the affinities to both invertebrates and vertebrates at the same time.

Phylum Chordata – it has the animals with the notochord. It is further separated into Urochordata, Cephalochordata, as well as Vertebrata.

Conclusion

Diversity in living world study material concludes that diversity can be found or experienced anywhere on this planet in the living organisms. The hot and humid regions on our planet are highly diverse as well as are known as the region of mega biodiversity. Moreover, it comprises all the living organisms on this planet, from a tiny cell to a giant elephant.
