Cranial nerves are sets of nerves that connect our brain to different parts of our head, neck and trunk. There are twelve cranial nerves which are named according to their function as well as structure. These are named using the Roman numerals based on their location in the body from the front to the back. These nerves are divided into two types based on their functions: i)Sensory nerve or ii)motor nerve Sensory nerves are the type of nerves which are connected with the …

Viruses caused epidemics in human with the variation in their behaviour, i.e. agricultural communities started developing, etc. during the
The banyan tree is a plant that grows on another plant when its seed germinates in a crack or fissure of a host tree or pile. Its scientific name is “Ficus benghalensis“, and is native to the Indian subcontinent. It is also the national tree of India.

He shared his thoughts about several aspects of the life of plants and animals. Aristotle is considered to be the Father of biology. He was the first person to inquire into biology systematically, and biology constitutes a large part of his compositions. He spent two years examining and explaining the zoology of Lesbos and the surrounding seas, including in particular …
Locomotion is one of the significant characteristics of CREATURES that differentiate them from other living and non-living things. This is simply because of the bones and muscles present in their body. Based on the structure of joints, these are classified into three types: Fibrous Joints These are the immovable joints where bones are fixed, i.e. not flexible. These joints have no cavity and are joined by connective tissues which are made up of collagen. Example of fibrous joints includes the upper jaw, …
In our day to day life, we come across a variety of things that we do not tend to notice. Our planet ‘Earth’, in which we live itself surrounded by plenty of varied ‘things’ or ‘species’. These “things” comprised of two basic types–“ Living” and “Non-living”. Each of these types is entirely different from each other. Both of these have their own set of rules by which they categorised from each other. But If something obeys only a few rules, …
Blood is regarded as connective tissue because it consists of a non-living fluid in which living cells are present. It has three main functions, namely transportation, regulation and protection. Cells in the blood are of 3 Structure types: red blood cells (erythrocytes), white blood cells (leukocytes) and platelets (thrombocytes). These make up 45% of our blood volume, the rest of the 55% is composed of plasma. Difference between prokaryotic cells vs eukaryotic cells Structure of Red Blood Cells: Red blood cells …
The human eye is an organ that reacts in light and allows light perception, colour vision, and depth perception. A structure inside the eye called the cornea focuses light onto a light-sensitive membrane called the retina, which is similar to a camera lens that focuses light onto film. Engrained in the retina are millions of light-sensitive cells, known as rods and cones. Rods enable the monochrome vision required in poor light, while cones enable colour vision and the detection …
“Biology is defined as the study of living organisms, their origins, anatomy, morphology, physiology, behaviour, and distribution.” Life is present in every corner of this planet, from the frozen Arctics to the searing Sahara. With over 8.7 million species documented till date, the earth is the only planet in the universe where life is known to exist. Advancements in technology have opened even more insights about life and its constituents. For instance, major discoveries such as viruses have scrutinized traditional …

Two Basic Types of Cells 1.Prokaryotic cells: Prokaryotic cells are evolutionarily ancient. They were here first and for billions of years were the only form of life. Today most life is prokaryotic, and these cells are supremely successful. All bacteria and bacteria-like Archaea are prokaryotic organisms. 2. Eukaryotic cells: Eukaryotes can be single-celled or multi-cellular organisms. Eukaryotic cells are more complex, having evolved from a prokaryote-like predecessor. Most of the living things that we are typically familiar with are composed …

Liquid water is the primary cause of life on Earth. Rivers, lakes, and the ocean are forms of naturally formed waterways. Earth is covered with 71% of water bodies. What is Ecosystem Engineer? One of the interesting topics in biology is the role of ecosystem engineers. An ecosystem engineer is any living being that creates, modifies, supports or destroys an …

Fruits are a product of fertilization. Generally, fruits will germinate into plants that will flower, offering another opportunity for fertilization. But the bananas bear tiny almost-remnants of seeds that will not germinate, but the wild, banana “fruits” have seeds. The botanical term parthenocarpy refers to the development of ovary of a flower into a fruit without fertilization, and these fruits are seedless. Fruits that develop parthenocarpically are generally seedless. Some seedless fruits come from sterile triploid plants, with sets of …
