Synonyms: Chondriosomes, Sarcosome, Plastosome, Fachsinophilic granules, Bioblast, Power houses, ATP mills, Storage batteries cellular furnace, biochemical machine, cell within a cell, or enuosymbiont in cell. Definition: Mitochondria are the filamentous, self-duplicating, double membranous cytoplasmic organelles of eukaryotic cells which are concerned with cellular respiration. Occurrence: They are the energy transducing organelle found in all aerobic eukaryotic cells. But in mature [...]

(i) Nuclear Envelope (Karyotheca): The nucleus is surrounded by a nuclear envelope, consists of two parallel membranes, separated by a fluid filled perinuclear space (10-15 nm width). The outer nuclear membrane is continuous with the membrane of endoplasmic reticulum at several places and its outer face is studded with ribosomes. The nuclear envelope is supported by nuclear lamina from inside [...]

Some of the major functions of cell membrane of eukaryotic cell are as follows: 1. Compartmentalization 2. Selective Permeability 3. Cellular recognition and adhesion 4. Cellular movements 5. Vital functions 6. Receptors 7. Enzymes 8. Disease. 1. Compartmentalization: The cell membrane encloses the protoplasm and maintains the individuality of the cell. Prokaryotic cell is a uni-compartment system while eukaryotic cell [...]
