Centrosomes and centrioles are two distinct structures found in eukaryotic cells that play critical roles in cell division and organization. While these two structures are often discussed in tandem, they are not the same thing and serve different functions within the cell. In this essay, we will explore the key differences between centrosomes and centrioles, including their structure, function, and relationship to other cellular components. What are Centrosomes? Centrosomes are the larger of the two structures and are found in animal cells, though they are absent in plants and fungi. They are composed of two centrioles, which are cylindrical structures ...

Skin is the largest organ of the human body and serves as a protective barrier between the body and the external environment. It helps to regulate body temperature, protects against infections, and helps prevent excessive water loss. However, the skin is not uniform throughout the body, and the thickness of the skin varies in different parts. This variation is due to the presence of different layers of the skin and the presence of different types of tissues and cells within each layer. Thin skin and thick skin are two types of skin, and the differences between them are primarily due ... Read More

Introduction Tissues are the supporting units found in living organisms throughout their bodies. These tissues are found in the bodies of plants and animals however they are different in structure and function entirely. These units have their own set of functionalities that supports different organs of the body. The tissues are made of cells and the plant and animal cells vary in terms of shapes and sizes. What is a Tissue? The union of cells forms tissue that is found in an organism and they share the same embryonic origin aiming towards a similar function. Multiple tissues accumulate to ...

Introduction Monocotyledonous plants have large chromosomes, which are nicely visible in the experiments. The meristematic tissues that are enabled at the tip of the roots provide a good source for the study of the process of mitosis. Onions are monocotyledonous plants possessing large chromosomes, hence their root tip is used for studying. Aim Cell division is required for maturation, growth, maintenance of the tissues, repairing of cells and others. The aim of the experiment is to study and demonstrate the process of mitosis through the preparation of the mount of an onion root tip. Main Theory of the ... Read More

Stem cells are cells that have the ability to differentiate into other cell types, making them useful in a variety of medical applications. There are several different types of stem cells, but two of the most commonly discussed are pluripotent and multipotent stem cells. While both types of stem cells have the ability to differentiate into other cell types, there are important differences between them. What is Pluripotent Stem Cell? Pluripotent stem cells are cells that have the ability to differentiate into any of the three germ layers of the developing embryo: ectoderm, mesoderm, and endoderm. These cells are derived ...

Introduction and History The membrane is an essential component of every living cell, which separates the cell from its external environment and provides a barrier to the free movement of molecules. The discovery of the cell membrane is attributed to the experiments of Robert Hooke and Anton van Leeuwenhoek in the seventeenth century, who first observed cells and bacteria under a microscope. In the nineteenth century, researchers discovered that cells were surrounded by a thin layer of material, which later became known as the cell membrane. The concept of the cell membrane’s structure and composition began to take shape ... Read More

Introduction Endosomes are essential components of the eukaryotic cell’s endocytic pathway. They are dynamic membrane-bound organelles that are responsible for sorting and transporting materials from the cell surface to various intracellular compartments. Endosomes are classified into several types, each with specific functions and characteristics. In this article, we will discuss the various types of endosomes and their functions. Types of Endosomes Early Endosomes Early endosomes are the first endocytic compartments to which internalized materials are delivered. They are characterized by the presence of early endosome antigen 1 (EEA1) and Rab5 GTPase. Early endosomes are responsible for sorting cargo ... Read More

Meiosis Cell Division

Introduction The cell cycle in eukaryotes usually comprises two distinct processes, namely, mitosis and meiosis. Mitosis occurs in somatic cells and ensures the division of a parent cell into two daughter cells that carry the same number of chromosomes as were present originally in the parent cell. Hence, the level of ploidy is maintained, or the division of chromosomes is equational, in mitosis. However, things are vastly different in meiosis. Meiosis is strictly a feature of progenitor gametic cells. This kind of cell division is crucial in the sexual reproduction of eukaryotes. At the end of meiosis, four daughter cells ... Read More

Introduction Imagine a deer fleeing for its life as it is being chased to death by a predatory cheetah. The deer runs fast and during this its breathing rate increases, and heart pounds furiously in anxiousness. Its legs move the fastest they possibly can. Such intense physiological responses to an external threat (stimulus) are a part of the deer’s flight-or-fight response, wherein the nervous system, muscular system, and skeletal system work together to respond aptly. Such and other responses including wound healing, defense against pathogens, etc., are made possible only through cellular signaling and communication. How does the body know ... Read More

Introduction Every organism whether single-celled or multicellular is made up of cells. They provide body shape and structure and perform a variety of tasks to keep it running. A cell is the fundamental unit of life. According to Cell Theory Hypotheses, “Cell is the fundamental unit of life that gives everything and is self-sufficient in performing all of an organism's essential activities.” What are Cell Organelles? Images Coming soon They make up a cell and make it operate normally by coordinating and working effectively. Depending on the presence or absence of membrane organelles are of three types having unique structures ... Read More
