Cilia Definition Characteristics of Cilium Structure of Cilium Cilia are extracellular protrusions that are membrane-bound, microtubule-containing, and formed from centrioles. They are structurally durable, as well as flexible and dynamic, having different mechanisms that regulate their composition and functions. On the basis of the patterns of microtubules found in the axonemes of the cilia, motile cilia … Read more
What is Fluid Mosaic Model of Plasma Membrane? – Fluid Mosaic Model Definition The fluid mosaic model is one method to comprehend biological membranes, consistent with the majority of experimental findings. According to this hypothesis, membrane components such as proteins and glycolipids form a mobile mosaic in the fluid-like environment formed by a sea of … Read more
What is Cell proliferation? What is Normal cell proliferation? The delicate balancing act between cell growth, division, differentiation, and death is what allows for normal cell proliferation, an essential function in the body. Diseases can be caused by disruptions in any of these systems, thus they’re all crucial. Proliferation and apoptosis are two processes that … Read more
Cell Coat Definition Extracellular Materials Cell Coat Function In addition to safeguarding the plasma membrane, the cell coat serves the following essential purposes: (i) Filtration (ii) Maintenance of the micro-environment of the cell (iii) Enzymes (iv) Immunological properties of the extraneous coats (v) Histocompatibility
What is Mitosis? Definition of Mitosis Mitosis is a cellular process in which a single eukaryotic cell divides to produce two genetically identical daughter cells, each maintaining the same number of chromosomes as the parent cell. Features of Mitosis In essence, mitosis is a meticulously regulated process that ensures genetic consistency, facilitates growth, and aids … Read more
What is Meiosis? Definition of Meiosis Meiosis is a specialized form of cell division in sexually reproducing organisms that results in four non-identical haploid cells (gametes) from a single diploid parent cell, ensuring genetic diversity and maintaining consistent chromosome numbers across generations. Types of Meiosis Meiosis occurs in the germ cells of organisms that reproduce … Read more
What is gametogenesis? Gametogenesis Definition Gametogenesis is the biological process through which precursor cells undergo cell division and differentiation to form mature sex cells or gametes. Spermatogenesis 1. Formation of Spermatids Primary germinal cells or primordial cells refer to the male germinal cells that create sperm. The primordial cells undergo the following three steps in … Read more
Fertilization Definition External and Internal Fertilization Fertilizin and Antifertilizin Fertilizin Antifertilizin Process of Fertilization The two sequential steps of the fertilisation process are as follows: 1. The egg’s activation; 2. The amphimixis. 1. Activation of the Egg The process of activation of eggs is completed in following stages : (i) Movement of the sperm towards … Read more
Necrosis refers to irreversible cell damage and subsequent cell death resulting from pathogenic processes. It is an uncontrolled cell death that leads to enlargement of the cell organelles, plasma membrane rupture and final lysis of the cell, and intracellular contents leaking into the surrounding tissue, resulting in tissue injury. Unlike programmed cell death known as … Read more
