Who first discovered endoplasmic reticulum?
ER discovered by Emilio Veratti in the year of 1902 as Sarcoplasmic Reticulum in muscle fibers which is similar to ER in other cells (Veratti, 1961). Fifty years later, this new organelle was first visualized through electron microscopy (EM) by Keith Porter and termed it as “endoplasmic reticulum” (Porter, 1953).
Who is the father of endoplasmic reticulum?
Porter and Thompson (1945) discovered Endoplasmic Reticulum. In 1953 Porter gave the name endoplasmic reticulum.
When was the ER discovered?
Discovery of Endoplasmic Reticulum (ER):
It was discovered independently by Porter (1945) and Thompson (1945). The name was given by Porter in 1953. Endoplasmic reticulum is a 3-dimensional, complicated and interconnected syncrri of membrane-lined channels that run through the cytoplasm.
Where was the endoplasmic reticulum discovered?
The smooth endoplasmic reticulum is especially abundant in mammalian liver and gonad cells. The ER was observed with light microscope by Garnier in 1897, who coined the term ergastoplasm.
Who discovered Golgi complex?
Camillo Golgi
The existence of the cell organelle which is now known as Golgi apparatus or Golgi complex, or simply as ‘the Golgi”, was first reported by Camillo Golgi in 1898, when he described in nerve cells an ‘internal reticular apparatus’ impregnated by a variant of his chromoargentic staining.
Who discovered the lysosomes?
Christian de Duve
Christian de Duve, whose laboratory in Louvain discovered lysosomes in 1955 and defined peroxisomes in 1965, died at his home in Nethen, Belgium at the age of 95, on May 4, 2013.
How was endoplasmic reticulum named?
The endoplasmic reticulum is one of the most intriguing and fascinating organelles. … Porter distinguished the exoplasm, a peripheral region devoid of organelles, from the adjacent endoplasm. In the endoplasm he detected a fine network of interconnected tubules, a reticulum; hence, the name “endoplasmic reticulum” (ER).
Who discovered cytoskeleton?
In 1903, Nikolai K. Koltsov proposed that the shape of cells was determined by a network of tubules that he termed the cytoskeleton.
Who discovered plasma membrane?
A cell membrane is also called the plasma membrane, a thin membrane that surrounds every living cell. Cell membranes are composed primarily of fatty-acid-based lipids and proteins. Robert Hooke discovered the cell membrane in the late 1600s.

Who discovered nucleolus?
Felice Fontana
Felice Fontana in 1774 discovered nucleolus. It is a dense region rich in DNA, RNA, and proteins that are formed from nucleolar organizing regions which are specific regions on chromosomes.
Who discovered ribosomes?
George E. Palade
In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane.
Who discovered cytoplasm?
History. The term was introduced by Rudolf von Kölliker in 1863, originally as a synonym for protoplasm, but later it has come to mean the cell substance and organelles outside the nucleus.
Who discovered centrosome and centrioles?
Theodor Boveri
Edouard Van Beneden made the first observation of centrosomes as composed of two orthogonal centrioles in 1883. Theodor Boveri introduced the term “centrosome” in 1888 and the term “centriole” in 1895.
Who is the father of the cell?

Who is the father of chromosome?
Discovery. It was first noted that the X chromosome was special in 1890 by Hermann Henking in Leipzig. Henking was studying the testicles of Pyrrhocoris and noticed that one chromosome did not take part in meiosis. Chromosomes are so named because of their ability to take up staining (chroma in Greek means color).
