Chromosome Abnormalities – Types, Mechanism, Detection
A chromosome disorder, also known as Chromosome Abnormalities is caused by an alteration in the size or the structure of chromosomes.
Cell Biology
Cell biology is the branch of biology that studies cells, the basic units of life. It is concerned with the structure, function, and behavior of cells, as well as the ways in which they interact with their environment.
Cells are the fundamental building blocks of living organisms. They are the smallest unit of life that can perform all the functions necessary for life, including metabolism, growth, reproduction, and response to stimuli. Cells are also the basic unit of structure in all living organisms, from simple single-celled organisms to complex multicellular organisms such as animals and plants.
Cell biology seeks to understand the properties and behaviors of cells in order to understand how they function and how they interact with their environment. This includes studying the various organelles within cells, such as the nucleus, mitochondria, and ribosomes, and how they work together to carry out the functions of the cell. It also includes studying the way in which cells communicate with each other and their environment, as well as the mechanisms by which they grow and divide.
Overall, cell biology is an important field of study that helps us understand the fundamental processes of life and how they are regulated at the cellular level.
Cell biology is an important field of study because it helps us understand the fundamental processes of life and how they are regulated at the cellular level. This knowledge is critical for many areas of science and medicine, including the development of new drugs and therapies, the understanding of diseases and disorders at the cellular level, and the study of the evolution of cells and organisms.
Some specific examples of the importance of cell biology include:
Understanding the causes of diseases: By studying cells and how they function, scientists can identify the underlying causes of many diseases and disorders. This can help in the development of treatments and therapies that target specific cells or processes in the body.
Developing new drugs and therapies: The knowledge of cell biology can be used to develop new drugs and therapies that target specific cells or processes in the body. For example, many cancer therapies are designed to target and kill cancer cells, while others are designed to stimulate the immune system to attack cancer cells.
Improving our understanding of the body: By studying cells and how they function, we can gain a better understanding of how the body works as a whole. This knowledge can be used to improve healthcare and prevent or treat diseases and disorders.
Studying the evolution of cells and organisms: By studying the structure and function of cells, we can learn about the evolution of cells and organisms over time. This can help us understand how different organisms are related and how they have adapted to different environments.

Red Blood Cell – Morphology, Size, Shape, Color and Inclusion Bodies
Red blood cells constitute the primary cellular component in blood. Red blood cells that are mature are biconcave discs which have no nucleus and are devoid of most cell organelles , including the lysomes, endoplasmic-reticulum and mitochondria.
Types of Plant Cell
They are multicellular, eukaryotic cells which comprise the Plant (a collection of eukaryotes that belong to the Plantae kingdom ) capable of producing their own food from sunlight, water and carbon dioxide). Since they are eukaryotic they possess a distinct nucleus, with specially designed organelles that allow them to function in a controlled way.
