Structural Organisation in Animals and Plants

The collateral glands of insects are organs linked to the female genital apparatus. Collateral glands are two extremely branched tubular glands in cockroaches, which are uneven in size. Both the glands open at the back of the genital chamber. The secretion generated by these glands forms the oothecal case of the ootheca. It consists of […]

A coenzyme is a chemical that works with an enzyme to help it start or complete its action. It can be thought of as a supporting molecule in a biological reaction. Coenzymes are non proteinaceous tiny molecules that serve as a transfer site for a working enzyme. They function as intermediate carriers for an atom

Vertebrates are animals that have a vertebral column and/or a notochord at some point in their lives and are classified as such.The presence or absence of the vertebrate is one of the ways in which life can be classified, and this is one of the classifications used. Both vertebrates and invertebrates descended from a common

Introduction One of the foremost basic styles of classification of animals is the presence or absence of the notochord. Basically Notochord is a flexible rod-like structure of cells, working as a support for the body. Hence, 2 major terms exist, namely: Chordates and Non-chordates.  Chordates The spine could be a versatile rod created out of

Only around 15% of the estimated 8.7 million species are known to man, according to scientists. This means that over 85% of species have yet to be found. In the Animal Kingdom, there are only roughly 953,434 species of animals. Let’s have a look at how animals are classified. Classification of Animals Kingdom Animal classification

These organisms were among the first to successfully adapt to life on land. They are thought to have descended from amphibians millions of years ago, according to evolutionary theory. On the planet, there are approximately 10000 different species of reptiles. Cold-blooded animals belonging to the phylum Chordata of the Animal kingdom, they are also known

Mammalia are the animals that belong to the class Mammalia and are referred to as mammals. Mammals are one of the most evolved species in the animal kingdom, and they are classified as vertebrates, which means “vertebrates.” They possess advanced characteristics that distinguish them from all other animals on the planet. They are distinguished by

The avian taxonomic group Aves is composed of birds. Chordata is the phylum in which this class is classified (chordates). Their common characteristics include oviparous reproduction, full double circulation, wings (modified forelimbs), feathers, and a toothless beak (except for some Mesozoic fossil birds that have conical teeth in both jaws). Characteristics Aves is a class

Non chordates are creatures that have the notochord, a rod-like structure in their bodies. Chordates are animals with a notochord located somewhere on their bodies. Pharyngeal gill slits and a hollow nerve cord differentiate this group. The animal kingdom, sometimes known as Kingdom Animalia, is a well-known classification of living organisms on Earth. Members of
