Structural Organisation in Animals and Plants

Snakes are limbless, elongated carnivorous reptiles that belong to the Serpentes suborder. More than 3,500 reptile species have been described based on their lack of limbs and significantly elongated bodies and tails. Snakes are classified as lizards and belong to the Squamata order. Snakes have lost limbs and their structural complexity has been reduced over […]

To comprehend what is the scientific name of Rat is, or what the Botanical name of Rat is, we must first learn a few things about living creatures, the necessity for classification, and the procedures used to identify them. Living creatures exhibit several unique and distinguishing traits. Such traits aid in the classification of living

Taxonomic hierarchy is defined as “the process of arranging various organisms into successive levels of biological classification, either in descending or ascending order from kingdom to species and vice versa.” An equal level of the hierarchy is referred to as a taxonomic category or rank. taxon (plural: taxa) is a unit of classification for a

The pineal gland, also known as the conarium, epiphysis cerebri, pineal organ, or pineal body, is a vertebrate endocrine gland that produces melatonin, a hormone derived from tryptophan that plays an important role in the regulation of circadian rhythms (the roughly 24-hour cycle of biological activities associated with natural periods of light and darkness). The

Symbiosis comes from two Greek words that mean with and living. It describes an ecological relationship between two organisms from different species that are sometimes, but not always, beneficial to both parties.  Symbiosis is an intimate, long-term and specific association between organisms of two or more species. This definition is largely identical to the original concept

Sublingual gland (called Capḷiṅkuval curappi in tamil) One on each side of the frenulum, lateral to the Wharton duct in the submucosal compartment, the pair of sublingual glands are positioned in the floor of the mouth, one on each side of the frenulum. These glands drain either directly into the mouth’s floor via the Rivinus

In the living world, there are single-cell and multicellular organisms. Each organism has specific processes and systems that work together to perform metabolic activities that keep the organism alive. While single-cell organisms perform all these functions in a single cell, multicellular organisms have several cells specialised for specific functions. This specialisation of cells in animals

Animals and all other lifeforms share the same fundamental structural organisation. Or, to put it another way, cells make up every living thing that exists now on Earth. And tissues are created when cells come together. In turn, tissues create organs and organ systems. Animals’ structural organisation begins with their smallest basic unit, the cell.

Only a few enzymes exhibit absolute specificity property when they catalyze for only one particular reason ( a particular fixed reaction). Other enzymes will be specific for a particular type of chemical bond or functional group. The property of enzymes describes how restrictive the enzymes are in their choice of any substrate ( a completely

Gastropod includes Snails and slugs from saltwater, freshwater and land. Gastropod previously called Univalves. The anatomy, behaviour, feeding and reproductive adaptions of gastropods fluctuate considerably from one clade to another.  Snail Snail is the family of gastropod animals that tends to have an enclosing covering into which they can withdraw completely for safety. They fall
