What is Liposome? Liposomes, derived from the Greek words “lipo” (fat) and “soma” (body), are spherical vesicles characterized by at least one lipid bilayer. These structures are primarily composed of phospholipids, notably phosphatidylcholine, and often incorporate cholesterol. Other lipids, such as those present in eggs and phosphatidylethanolamine, can also be integrated, provided they are congruent … Read more
What is Integral Protein? Definition of Integral Protein An integral protein is a type of protein that is permanently anchored within the cellular membrane, often spanning its entire width, and plays crucial roles in various cellular functions due to its specific functional domains. Integral Protein Types Integral proteins, a pivotal component of cellular membranes, can … Read more
What are Daughter Cells? Definition of Daughter Cells Daughter cells are the cells resulting from the division of a single parent cell, either through the process of mitosis, where they inherit identical genetic material, or meiosis, where they receive half the genetic content. Characteristics of Daughter Cells Daughter cells are the end products of cellular … Read more
What is Prokaryotic Ribosomes? Definition of Prokaryotic Ribosomes Prokaryotic ribosomes are molecular complexes consisting of ribonucleic acid (RNA) and proteins that facilitate protein synthesis within prokaryotic cells, such as bacteria and archaea. Ribosome Subunits Ribosomes, intricate molecular complexes responsible for protein synthesis, consist of two essential subunits in prokaryotic cells, collectively referred to as the … Read more
What is Diploid Cell? Definition of Diploid Cell A diploid cell is a cell that contains two complete sets of chromosomes, one inherited from each parent. Features of diploid cells Diploid cells are integral to the genetic architecture of many organisms. Here are the salient features of these cells: Diploid cells in Human body In … Read more
What is Embryology? Definition of Embryology Embryology is the scientific study of the formation, development, and growth of embryos and fetuses within organisms. History of Embryology The historical trajectory of embryology is a testament to humanity’s enduring quest to understand the origins and development of life. This journey, spanning diverse civilizations, offers a rich tapestry … Read more
What is Embryonic Stem Cell? Definition of Embryonic Stem Cell Embryonic stem cells (ESCs) are pluripotent cells derived from the inner cell mass of a blastocyst, an early-stage embryo, capable of differentiating into any cell type within an organism. History of Embryonic Stem Cell The history of embryonic stem cells (ESCs) is marked by pioneering … Read more
What is Endosymbiosis? Definition of Endosymbiosis Endosymbiosis is a form of symbiosis in which one organism (the endosymbiont) lives inside the cells or body of another organism (the host), often resulting in mutual benefits for both entities. Endosymbiotic Theory The Endosymbiotic Theory offers a comprehensive explanation for the evolutionary transition from prokaryotic to eukaryotic cells. … Read more
What is Eukaryotic Cell? Definition of Eukaryotic Cell A eukaryotic cell is a type of cell characterized by a membrane-bound nucleus and the presence of various organelles within its cytoplasm, distinguishing it from prokaryotic cells which lack a true nucleus. Eukaryotic cells are found in organisms such as plants, animals, fungi, and many unicellular entities. … Read more
What is Food Vacuole? Definition of Food Vacuole A food vacuole is a membrane-bound organelle found in certain cells, especially protozoan microorganisms, that encloses and digests ingested nutrients using digestive enzymes, subsequently releasing the digested molecules into the cytoplasm for cellular utilization. Structure Of Food Vacuole The food vacuole, a specialized cellular compartment, is characterized … Read more
