Endoplasmic reticulum Golgi body and ribosomes
The endoplasmic reticulum and Golgi body are single membrane bound structures the membrane has the same structure Leopard protein as the plasma membrane songs do not have membranes ribosomes are involved in synthesis of proteins in the cell golgi bodies in secreting and the year in and storing the products organelles operate together endoplasmic reticulum
Structure
Network of membranes with thickness between 50 to 60 is of two types rough endoplasmic reticulum are when ribosomes are attached to 8 and smooth endoplasmic reticulum STR when no ribosomes are present
Tad throughout the cytoplasm and is in contact with the cell membrane the nuclear membrane
Functions
Provides internal Framework compartment and reaction surfaces enzymes and other materials throughout the cell is the site for protein synthesis and SCR for steroid synthesis stores carbohydrates
Golgi body
Structure
Stack of membranous sex thickness as endoplasmic reticulum
Exhibit great diversity in size and shape and animals present around the nucleus 327 in number many in number of and present scattered throughout the cell called dictyosomes
Function and secretion as enzymes party separates and transformation of membranes to give rise to other membrane search age lysosome acrosome and dictyosomes wall element like pectin mucilage
Ribosomes
Structure
Spherical about 150 to 250 angstrom in diameter made up of large molecules of RNA and proteins ribonucleoproteins present either as free particles in cytoplasm or attached to endoplasmic reticulum also found stored in nucleolus inside the nucleus found in eukaryotes and 70s in prokaryotes as she is Marg unit of measuring ribosome
Function
Ribosome is the site for the protein synthesis
