Question

The functional unit of Golgi apparatus is
A) Thylakoids
B) Oxysomes
C) Cristae
D) Cisternae

Answer 1

Hint: Golgi apparatus is an organelle found in the eukaryotic cells which forms a complex of vesicles and folded membranes within the cytoplasm that is involved in the secretion and helps in intercellular transport. hey helps in modifying, sorting, and packaging of proteins for secretion and also helps in the transportation of lipid and forms lysosomes.

Step by step answer:The faults of the Golgi body are called cisternae which are called the functional units of this organelle. Golgi apparatus is a cell organelle That is found in the eukaryotic cell. It was first discovered by Camillo Golgi in 1897 by an Italian physics. Golgi apparatus Forms a complex of vesicles and folded membranes within the cytoplasm that is involved in secretion and helps in intercellular transport. The appearance of the cisternae it's generally compared to a stack of deflated balloons. vesicles that extended from the endoplasmic reticulum enter the stacks of the Golgi body. It plays an important role in the modification and transports of proteins generated in the endoplasmic reticulum within the cell. The main function of all of this apparatus is to direct the carbohydrates and proteins, needed by the body, to their proper destination. the functions of cisternae changes as it undergoes different stages of maturation. The immature cisternae receive vesicles from the endoplasmic reticulum. the next stage of this process begins then cisternae swap material via vesicles at carbohydrate synthesis. then the cargo proteins are sent two transport that here are the immature cisternae reach the final stage.
Thus, the answer is option D: Cisternae.

Note: A cisterna is a flattened membrane disk of the endoplasmic reticulum and Golgi body. A Golgi stack may contain anywhere from three to twenty cisternae, but most contain about six cisternae.
