Introduction Our earth is made up of nearly 70% water. The human body is made up of 60% water. It is one of the six vital nutrients that are necessary for our survival. Other than that, we need a constant water supply for our day-to-day activities like bathing, cleaning, watering plants, etc. Additionally, industrial operations require a large amount of water for heating and cleaning purposes. Water also acts as a solvent for many chemical and biological processes. However, the rapidly increasing population and industrialization have led to immense pressure on water resources. Many parts of the world are already ... Read More

Introduction Plastics are made up of polymers that are derived from petroleum products and it becomes versatile product because of their significant properties and applications. The varied types of plastics exist in different objects such as polyethylene terephthalate in plastic bottles, polyvinyl chloride in toys, polythene in plastic bags, and other products. It was initially considered a non-toxic and inert material, however, the number of uses of plastics make harmful effects. Therefore, plastic products provide a serious environmental burden to society. Wind and water can cause the plastics to transfer from one place to a different place and make plastic ... Read More

Introduction Kingdom Plantae is a vast group which includes all the plants on the globe along with some algae. They are usually chlorophyll-containing, multicellular, autotrophic, primary food producers in the ecosystem. Kingdom Plantae is divided into many subgroups due to its vastness. Their classification is based on the plant structure, vascular system and seed development. Kingdom Plantae is subdivided into two divisions such as Cryptogamae and Phanerogamae. Angiosperm and gymnosperm are two groups that come under the subkingdom called phanerogams. They are seed-bearing plants with a vascular system. The Vascular system is nothing but the presence of vascular tissues like ... Read More

Introduction to Bt Crops Bt crops are genetically modified crops. Bt is a gram-positive soil bacteria that produce insecticides naturally. The insect-resistance soil bacteria is known as Bacillus thuringiensis. The bacteria produce insecticides when oxygen and nutrients are insufficient for their vegetative growth. At this time bacteria, sporulates and spore contains one or more insecticides. Bt bacteria produces three types of insecticides proteins namely cry proteins, cyt proteins, and vip proteins. These three proteins' insecticides are effective against different types of insecticides. Although these three components are effective against insecticides cry protein is considered to be the most effective for ... Read More

Introduction The phylum Bryophyta is a group of ~12, 000-14, 000 species of non-vascular plants represented by the mosses, the liverworts, and the hornworts, belonging to the sub-kingdom Embryophyta. These are non-woody herbaceous plants with a relatively small and simple body structure. Famously referred to as the “amphibians of the plant kingdom”, these plants hold significant ecological and economic importance. General features of Bryophytes Bryophytes are the “amphibians of the plant kingdom” because they require a lot of moisture and humidity for their growth Body organization may be leafy and thalloid. The leafy forms have simple leaf-like ... Read More

Introduction During fertilization, the development of the embryo also begins, in which a simple embryo having very less diverse cell types is gradually converted to a complex organism with diverse cell types. The development includes a series of processes − Fertilization is of three types − External fertilization (Sea urchin and Frog) Internal fertilization in mammals Double fertilization in Angiosperms. What is Blastocyst? The structure which is formed in the early developmental process characterized by Inner cell mass (ICM) which eventually will form an embryo and outer layer which is called trophoblast which forms the placenta. Images ... Read More

Introduction The animal kingdom is vast with extremely diverse living organisms. The flying animals are commonly referred to as birds although they are systematically placed under the Class Aves. It includes all the feathered homeothermic, warm-blooded animals with specialised organs for flying. It includes more than 10, 000 species. Their sizes vary from tiny two-inch-sized hummingbirds to 9 feet-tall ostrich which are the largest of all birds. Morphological features like a beak (shape and size), wing size, nutrition, and plumage differ with the species and each characteristic has its unique importance in the species survival and continuance. Characteristics Although the ... Read More

Introduction to biotechnology Biotechnology is the study where technology is applied to various living organisms for the benefit of human life. Although the name itself says ‘Bio’, it is an amalgamation of multiple streams like biology, chemistry, mathematics, and technology. The sub-fields of Biotechnology are Cellular and Molecular Biotechnology, Stem cells and Regenerative Medicine, Immunology, Environmental Biotechnology, Biochemistry, Bioinformatics, Nano-biotechnology, Food, and Animal Biotechnology, etc. During the recent COVID-19 pandemic, Biotechnology has played a significant role in its prevention through vaccine development. Applications of Biotechnology for human welfare − Agriculture − Use of genetically modified organisms (GMO) for better ... Read More

Introduction to biosafety Biosafety is the structure that makes use of certain specific methodologies, guidance, security gear, and exceptionally built offices to safeguard workers, the surrounding area, and the environment from unexpected exposure to contagious agents and chemicals. A biosafety program puts measures in place to distinguish biohazards, evaluate the amount of risks related to health the biohazard offers to people, farming, wildlife, and the environment, and develop solutions to lower the dangers related to the biohazard. Biosafety has become more crucial than ever to protect the ecosystem as a result of the development in the fields of biotechnology and ... Read More
