Nucleus Structure and Function

Nucleus:- The nucleus is a double membrane-bound protoplasmic organelles which contain the genetic information for control cellular metabolism and transmission to the next offspring. The nucleus was first discovered in orchid root cells by Robert brown called it Areda. The study of the nucleus is called as Karyology. Flemming gave Read more…

Microbodies – Structure, functions, and Types

Microbodies:- Microbodies are small single membrane-bound organelle. They are formed by ER. They were first observed by Rhodin.They Found in protozoa, fungi, plants, and liver and kidney cells. Microbodies are four types:- 1. Peroxisomes:- Peroxisomes help in detoxifying the alcohol in the liver cell. Contains amino acid oxidase, hydroxyl acid Read more…

Vacuole Structure Functions and Types

Vacuole:- Vacuole is discovered by Dujardin.  It is unit membrane-bound structure which is selectively permeable. Approx.90% of the volume of many plant cells is occupied by it. It Is surrounding membrane is known as Tonoplast (Greek- ton meaning ‘stretching’, ‘tension’, ‘tone’ Plastos ‘formed, molded’ ) and fluid is cell sap, Read more…

Lysosome Structure Function and Types

LYSOSOME: – Lysosome word made by Greek Lyso- digestive, soma- body. It was discovered by C. De Duve. Alex Novikoff observed It in the cell with an electron microscope and coined the term lysosomes. This is a single membrane-bound small vesicular organelle rich in acid hydrolases that breaks all types Read more…

Golgi Complex Golgi Apparatus Golgi Body

Golgi complex: – Camillo Golgi first observed densely stained reticular structure near the nucleus in nerve cell . These were later named Golgi bodies after him. Golgi body is pleomorphic, i.e. it is morphologically different in different types of cells. Golgi apparatus is surrounded by a differentiated region of cytoplasm Read more…
