The following points highlight the eleven main organelles that eukaryotic cytoplasm possess. The organelles are: 1. Endoplasmic Reticulum (ER) 2. Golgi Complex 3. Lysosomes 4. Peroxisomes 5. Glyoxysomes 6. Spherosomes 7. Vacuole 8. Centrosome 9. Ribosomes 10. Chloroplast 11. Mitochondria. Organelle # 1. Endoplasmic Reticulum (ER): Endoplasmic reticulum is a highly convoluted sheet of membranes extending from the nuclear membrane. [...]
In this article we will discuss about:- 1. Ultrastructure of Mitochondria 2. Function of Mitochondria 3. Reproduction. Ultrastructure of Mitochondria: In 1953, Palade and Sjostrand independently described the ultrastructure of mitochondria. Mitochondria are bounded by an envelope consisting of two concentric membranes, the outer and inner membranes. The space between the two membranes is called inter-membrane space. A number of [...]
In this article we will discuss about:- 1. Meaning of Plasma Membrane 2. Chemical Composition of Plasma Membrane 3. Origin 4. Functions. Meaning of Plasma Membrane: The term 'Plasma membrane' was given by Pfeffer. It is situated just inside the cell wall and is also termed as cell membrane, plasma lemma or cytomembrane. The term 'Plasma lemma' was given by [...]
