Cell Nucleus Function | Its Structure & Importance in Cell’s Life

Every living cell has centrally placed circular and dusky structure called “nucleus“. The nucleus function is key to a cell’s normal survival. The cells with a well formed nucleus are called as  eukaryotic cells. The cells lacking this nucleus are called prokaryotic cells like bacteria. It is also absent in red blood cells (RBC‘s)and hence are called as corpuscles. Nucleus appears as […]

What is the Function of Mitochondria | 10 Important Points

mitochondria characteristics

Mitochondria is one of the vital cell organelles present inside the cell. Eukaryotic cell has at least one or more number of mitochondria depending on the requirement. But, those cells with high physiological activity posses a higher number of mitochondria. For example muscle cells and nerve cells have large number of them per cell. Similarly, those organs with low physiological activity have […]

Function of Carbohydrates: Physiological Importance in Body

functions of carbohydrates

Carbohydrates have prominent physiological importance in the body. Without them, there exists no physiology in the body and also life on the earth. After water and protein, they comprise the most abundant matter in the body and are significant nutrients of the body. The carbohydrate chemistry is comprised of 3 elements viz. carbon, hydrogen, and oxygen. So […]
