What do you mean by Environment? The settings in which life is found on Earth are referred to as the environment. The environment is made up of things like people, animals, sunlight, water, trees, and air. They are the elements of the earth, both living and non-living. Animals, humans, and plants are examples of living […]
The Earth’s biosphere is a tapestry of life, woven with an intricate web of interconnected species. This biodiversity, the very fabric of our planet’s ecosystems, is under immense pressure. Habitat loss, climate change, pollution, and invasive species are relentlessly eroding the richness and diversity of life. In this context, ex-situ conservation – the preservation of species outside

Polytene Chromosomes Large chromosomes called polytenes are seen in the salivary glands of insects. They were found by Balbiani in 1881. Polytene Chromosomes were found in the salivary glands, they are often referred to as salivary gland chromosomes. They are referred to as polytene because of their large number of chromonemata. Drosophila melanogaster larvae’s salivary

All living things go through a basic process called the cell cycle, which is in charge of tissue growth, development, and repair. The precise duplication of the cell’s genetic material (DNA) and the subsequent division of the cell into two daughter cells are guaranteed by a strictly controlled series of processes. The two primary stages
Immunofluorescent Using immunofluorescent, one of the most potent microscopy techniques, one can see certain molecules or structures inside cells and tissues. By using antibodies, which function as tiny, focused spotlights with extraordinary specificity, it can give the target molecule a luminous glow. Drosophila melanogaster, the common fruit fly, has proven to be a remarkably powerful

What do you mean by in vitro methods? Thus, in vitro methods are procedures that use elements of a living organism—such as tissues, cells, or enzymes—but in a lab-controlled environment. Compared to in vivo (within a living organism) approaches, this enables the study of biological processes in a more isolated and regulated manner. What do
Dicot root Dicot roots extend deeply into the soil as a single, thick root with lateral branches. This type of root structure is known as a taproot. The major vascular structures of dicot roots are surrounded by the ground tissue, which is mainly made up of parenchyma cells. Beneath the soil, hidden from the prying
What do you mean by Monocot stem? The term “monocot stem” describes the stem of a flowering plant that is monocotyledonous, or that kind of plant that has a single cotyledon (seed leaf) in its seeds. The seemingly simple structure of a grass stalk, a bamboo shoot, or a palm tree trunk hides a complex
What do you mean by dicot stem? The stem of a dicotyledonous plant, a kind of flowering plant distinguished by having two seed leaves (cotyledons) within the seed, is referred to as a dicot stem. Imagine a tiny seed sprouting into a delicate seedling. As it grows, its stem, the backbone of the plant, needs
What do you mean by Protoplast? The protoplast, which is able to perform all necessary functions for growth, development, and survival, is essentially the basic building block of life within a plant cell. Protoplast isolation is a technique used in plant and microbial biology to remove the rigid cell wall of a cell, leaving behind a protoplast.
