Meiosis- definition, purpose, stages, applications with diagram

Meiosis definition Meiosis is a type of cell division in sexually reproducing eukaryotes, resulting in four daughter cells (gametes), each of which has half the number of chromosomes as compared to the original diploid parent cell. The haploid cells become gametes, which by union with another haploid cell during fertilization defines sexual reproduction and formation … Read more Meiosis- definition, purpose, stages, applications with diagram

Mitosis- definition, purpose, stages, applications with diagram

Mitosis definition Mitosis is the process of cell division in which one cell gives rise to two genetically identical daughter cells, resulting in cell duplication and reproduction. The number of chromosomes is preserved in both the daughter cells. Mitosis is a short period of chromosome condensation, segregation, and cytoplasmic division. The mitosis occurs in the … Read more Mitosis- definition, purpose, stages, applications with diagram

Epithelial Tissue – Definition, types, functions, examples

Epithelial Tissue Types

Epithelial Tissue definition Epithelial Tissue is one of the four types of tissue (epithelial, muscular, connective, and nervous) in animals which consists of closely aggregated polyhedral cells adhering firmly to one another, forming cellular sheets that line the interior of hollow organs and cover the body surface. An epithelial tissue or epithelium (plural is epithelia) … Read more Epithelial Tissue – Definition, types, functions, examples

Simple Diffusion vs Facilitated Diffusion (11 Differences)

Simple Diffusion vs Facilitated Diffusion

Image Source: Khan Academy and Wikipedia Some of the differences are as follows: Characteristics Simple Diffusion Facilitated Diffusion Definition Simple diffusion is a type of passive transport which, as the name suggests, is simply the unassisted movement of solute which occurs when its electrochemical potentials on the two sides of a permeable barrier are different. … Read more Simple Diffusion vs Facilitated Diffusion (11 Differences)

Simple diffusion- definition, principle, examples, applications

Simple diffusion

Simple diffusion definition Simple diffusion is a type of passive transport which, as the name suggests, is simply the movement of solute which occurs when its electrochemical potentials on the two sides of a permeable barrier are different. While in other science disciplines like chemistry, diffusion refers to “spreading out” of molecules from a higher … Read more Simple diffusion- definition, principle, examples, applications

Speciation- definition, causes, process, types, examples

Speciation- definition, causes, process, types, examples

Speciation Definition Speciation is the process of formation of a new genetically independent group of organisms, called species, through the course of evolution. The process of splitting of genetically homogenous population into two or more populations that undergo genetic differentiation and eventual reproductive isolation is called speciation. The entire course of evolution depends upon the … Read more Speciation- definition, causes, process, types, examples

Facilitated Diffusion- definition, principle, factors, examples

Facilitated Diffusion

Facilitated diffusion definition Facilitated diffusion is the process of biological transport in which specific structural components of biological membranes interact with particular solutes or classes of solutes, markedly increasing the rates at which they can cross the membrane. It is a passive-mediated transport in which particles or substances are transported across a biological membrane from … Read more Facilitated Diffusion- definition, principle, factors, examples

Phylum Ctenophora- characteristics, classification, examples

Phylum Ctenophora

Ctenophora Definition Ctenophores are free-swimming, transparent, jelly-like, soft-bodied, marine animals having biradial symmetry, comb-like ciliary plates for locomotion, the lasso cells but nematocytes are wanting. They are also known as sea walnuts or comb jellies. Phylum Ctenophora Characteristics They are free-swimming, marine, solitary, pelagic animals. No polymorphism and no attached stages were found. The body … Read more Phylum Ctenophora- characteristics, classification, examples

Bacterial Transduction- Definition, Principle, Steps, Examples

Bacterial Transduction- Definition, Principle, Steps, Examples

Transduction Definition Transduction is the transfer of bacterial DNA from a donor to a recipient bacterium via a virus particle. The virus particle that infects bacteria is called a bacteriophage or phage, and the phages used for the transfer of DNA are called transfusing phages. Not all phages are transducing phages. The process of transduction … Read more Bacterial Transduction- Definition, Principle, Steps, Examples

Flow Cytometry-Definition, Principle, Parts, Steps, Types, Uses

Flow Cytometry Definition Flow cytometry is a standard laser-based technology that is used in the detection and measurement of physical and chemical characteristics of cells or particles in a heterogeneous fluid mixture. The use of flow cytometry has increased over the years as it provides a rapid analysis of multiple characteristics (both qualitative and quantitative) … Read more Flow Cytometry-Definition, Principle, Parts, Steps, Types, Uses
