Cell Organelles and Functions

What is the main function of the cell membrane?

• Produce energy for the cell

• Provide structural support to the cell

• Regulate the movement of substances in and out of the cell

• Store genetic material

What is the structure of the nucleus and what is its role in the cell?

• The nucleus is a type of ribosome that synthesizes proteins. Its role is to transport materials within the cell.

• The nucleus is a vacuole that stores water and nutrients. Its role is to provide structural support for the cell.

• The nucleus is a membrane-bound organelle that contains the cell's genetic material. Its role is to control the cell's activities and store the genetic information.

• The nucleus is a non-membrane-bound organelle that contains the cell's genetic material. Its role is to produce energy for the cell.

Explain the role of mitochondria in energy production within the cell.

• Mitochondria break down energy in the form of ATP through photosynthesis.

• Mitochondria produce energy in the form of glucose through photosynthesis.

• Mitochondria store energy in the form of DNA through cellular respiration.

• Mitochondria produce energy in the form of ATP through cellular respiration.

What is the difference between rough endoplasmic reticulum and smooth endoplasmic reticulum?

• Location within the cell

• Color of the membrane

• Presence of ribosomes

• Size of the organelle

How does the cell membrane regulate the movement of substances in and out of the cell?

• Random permeability

• Unregulated permeability

• Selective permeability

• Total permeability

What is the function of the nucleolus within the nucleus?

• Produces ribosomal RNA and assembles ribosomes

• Regulates the movement of substances in and out of the nucleus

• Synthesizes lipids for the cell

• Stores genetic material for the cell

Describe the process of protein synthesis in the endoplasmic reticulum.

• The Golgi apparatus is responsible for protein synthesis

• Ribosomes on the rough ER translate mRNA into a polypeptide chain, which is then folded and modified within the ER before being transported

• The endoplasmic reticulum stores proteins made in the cytoplasm

• Protein synthesis occurs in the nucleus

How do mitochondria generate energy for the cell?

• Photosynthesis

• Glycolysis

• Protein synthesis

• Cellular respiration

What are the functions of the Golgi apparatus in the cell?

• Produce energy for the cell

• Modify, sort, and package proteins and lipids

• Regulate cell division

• Store genetic information

Explain the relationship between the endoplasmic reticulum and the Golgi apparatus in protein synthesis and packaging.

• The endoplasmic reticulum synthesizes lipids and transports them to the Golgi apparatus for packaging and modification.

• The endoplasmic reticulum and Golgi apparatus have no relationship in protein synthesis and packaging.

• The endoplasmic reticulum synthesizes proteins and transports them to the Golgi apparatus for packaging and modification.

• The endoplasmic reticulum breaks down proteins and sends the components to the Golgi apparatus for disposal.
