Fragmentation is a type of asexual reproduction or cloning in multicellular or colonial organisms, in which an organism is broken into fragments. Each of these fragments matures into a fully grown adult who is a clone of the original creature. It’s possible that the organism will develop distinct organs or zones that can be readily […]

Fragmentation in multicellular or colonial organisms is a shape of an asexual replica or cloning, in which an organism is cut up into fragments. Each of those fragments changes into mature, absolutely grown people who can be clones of the authentic organism.  Fragmentation, also known as a splitting method of reproduction, is found in a

Introduction Students studying Biology might have come across the concept of reproducing asexually. The term ‘fragmentation’ refers to one recognised asexual reproductive form. As the name suggests, it is a sort of cloning in which one species is fragmented into small pieces. When these pieces are separated, they grow into fully developed individuals. A definition

Reproduction is a biological process in which a new individual organism is created by the union of two existing individuals. In general, plants reproduce either asexually, that is, without the generation of seeds, or sexually, that is, with the formation of seeds. The portions of plants that are involved in asexual reproduction are referred to

Fungus gnats are tiny insects that feed on organic breakdown in soil, potting mix, and other container media. Their larvae eat fungi and organic materials in the soil, but they also chew roots, making them a nuisance in greenhouses, nurseries, potted plants, and interior plantscapes. Indoors, adult fungus gnats can emerge from houseplants and cause

All organisms require food for survival and development. It is essential to increase food production to meet the growing population’s needs. The yield has increased by many folds through plant breeding, animal husbandry and modern technologies such as tissue culture, genetic engineering, and embryo transfer. Animal Husbandry It’s the practice of raising and breeding livestock (buffaloes or

The Cell cycle can be defined as the duplication and division of contents into two parts. It is an essential mode by which organisms can reproduce. Though the cell cycle is the basic mechanism to divide, it possesses the characteristic of passing on the hereditary characters to the progeny in an ordered sequence. For the

Introduction Essentially, the majority of our body’s cell division is accomplished by mitosis. Throughout our lives, it creates new cells and replaces old, worn-out ones. Mitosis’ purpose is to create daughter cells that are genetically similar to their mothers, down to the last chromosome. Meiosis is the reduction in the number of chromosomes in a cell

Introduction: Melia is the process by which a single cell divides twice, yielding four cells each containing half the amount of genetic information that was originally present in the cell. These newly formed cells are sex cells, which means that in females they are eggs and in males they are sperm. It is a method

Introduction Meiosis is also known as reduction division, where the division of a germ cell occurs and involves two nuclear fissions and produces chromosomes as can be seen in the original cell. In sexually reproducing organisms, meiosis is a process that occurs. As a result, a diploid (double) set of chromosomes, consisting of two haploid
