What is the function of the nucleus in a cell?

• Protein synthesis

• Energy production and storage

• Cell wall formation

• Control center and contains genetic material

Which organelle is responsible for protein synthesis in a cell?

• lysosome

• ribosome

• nucleus

• mitochondria

What is the function of the mitochondria in a cell?

• Produces energy (ATP) through cellular respiration

• Stores genetic material

• Synthesizes proteins

• Regulates cell division

What is the role of the endoplasmic reticulum in a cell?

• The endoplasmic reticulum stores genetic information

• The endoplasmic reticulum regulates cell division

• The endoplasmic reticulum is involved in protein and lipid synthesis, as well as in the transport of these molecules within the cell.

• The endoplasmic reticulum is responsible for cell movement

What are the two types of endoplasmic reticulum?

• Rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER)

• Rough endoplasmic reticulum (RER) and mitochondria

• Smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER)

• Rough endoplasmic reticulum (RER) and rough endoplasmic reticulum (RER)

What is the function of the Golgi apparatus in a cell?

• Produces energy for the cell
