Model Answer
Golgi body
- Cisternae are a series of five to eight cup-shaped compartments that make up the Golgi body.
- The Golgi apparatus is made up of flattened, disk-shaped, stacked pouches called cisternae.
- There are typically 4 to 8 cisternae in a Golgi stack. However, some protists have up to sixty cisternae.
- There are between 40 and 100 stacks of cisternae in a mammalian cell.
- Golgi apparatus is responsible for producing lysosome.
Smooth endoplasmic reticulum
- The smooth endoplasmic reticulum (SER) is a continuous membrane organelle in the cytoplasm of eukaryotic cells.
- It is responsible for the synthesis and storage of lipids, such as cholesterol and phospholipids, which are utilized in the production of new cellular membrane.
- It is a meshwork of fine disk-like tubular membrane vesicles.
Ribosome
- A ribosome is a complex sub-atomic machine found inside the living cells that produce proteins from amino acids during a cycle called protein combination or interpretation.
- All living cells are responsible for the primary function of protein synthesis.
- Both prokaryotic and eukaryotic cells contain ribosomes, which are highly specialized organelles of the cell.
- Ribosomes are necessary for the production of proteins in every living cell.
Lysosome
- Digestive enzymes are contained within a membrane-bound cell organelle known as a lysosome.
- Lysosomes play a role in a variety of cell processes. They decompose worn-out or excessive cell components.
- They can be used to kill invading bacteria and viruses.
