Cytology is also known as cell biology. It is the study of the cell. It is important for researchers or biologists in the generation of vaccines, medications, etc.
Definition of cytokinesis Cytokinesis is the final process in eukaryotic cell division, which divides the cytoplasm, organelle, and cellular membrane. Cytokinesis after telophase usually occurs at the end of mitosis, but there are two independent processes. In most animals, cytokinesis begins in late anaphase or early telophase, to ensure that the chromosomes are completely separated. … Read more
Osmosis Definition Osmosis is a biophysical process that typically occurs in biological systems where the molecules of the solvent move towards a region of high solute concentration in a semi-permeable membrane. It is a type of passive transport and is directed towards a direction that equates solute concentrations across a semi-permeable membrane. It is a common … Read more
What is Interphase? Cells undergo continuous cell division, through which daughters cells are produced, which mature and also form their daughter cells, and this cycle continues. Cell cycle events include cell growth and cell division, the difference of which defines the stage of cell development where multiple metabolic reactions occur. Interphase is the preparation stage … Read more
Apoptosis definition Apoptosis is a normal genetically programmed cell death where an aging cell at the end of its life cycle contracts and its remaining fragments are phagocytosed without any inflammatory reaction. The term apoptosis was first introduced in an article in 1972 by Kerr, Wyllie, and Currie to describe a morphologically distinct type of … Read more
Definition of neutrophils Neutrophils are a type of white blood cell with multilobed nuclei and stainable cytoplasmic granules. These are the most abundant granulocytes, occupying about 40-60% of the total number of white blood cells in the blood. Neutrophils, like all other blood cells, are formed from stem cells in the bone marrow. After differentiation … Read more
Definition of centrioles Eukaryotic cells contain two rod-shaped, microtubular, cylindrical structures, called centrioles, near the nucleus. They lack a limiting membrane and no DNA or RNA and are found in most algae cells (a notable exception being red algae), moss cells, some fern cells, and most animal cells. They are absent in prokaryotic plants, red … Read more
Animal cell definition, Diagram, Function, Organelles, Parts What is an animal cell? Animal cells are the basic unit of life in organisms in the Animalia kingdom. They are eukaryotic cells, which means they have a true nucleus and specialized structures called organelles that carry out different functions. Animal cells do not have plant-specific organelles like … Read more
Mitochondria Definition Mitochondria are structures specific to the cells of animals, plants, and fungi. They act as batteries, powering the various functions of the cell and the organism as a whole. Although mitochondria are an integral part of the cell, evidence suggests that they evolved from primitive bacteria. What are mitochondria? Numerous small, spherical, club-shaped, … Read more
Cytoplasm Definition, Properties, Function, and structure What is cytoplasm? The cytoplasm contains all the contents outside the nucleus and is enclosed within the cell membrane of a cell. It is clear in color and has a gel-like appearance. The cytoplasm is mainly composed of water but includes enzymes, salts, organelles, and various organic molecules. Properties … Read more
Vacuoles Function, Definition, Types and Structure A vacuole is an organelle in cells that works to hold various solutions or materials. This includes solutions that have been created and stored or excreted and those that have been engulfed or engulfed by the cell. A vacuole is simply a chamber surrounded by a membrane, which prevents the cytosol … Read more
