Cell Structure and Functions

What is the main function of the cell membrane?

• Produce energy for the cell

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

• Store genetic information

• Provide structural support to the cell

Which organelle is responsible for producing energy for the cell?

• nucleus

• ribosomes

• mitochondria

• endoplasmic reticulum

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

• Generating energy for the cell

• Regulating cell division

• Storing genetic information

• Modifying, sorting, and packaging proteins and lipids

What is the role of the nucleus in a cell?

• Produces energy for the cell

• Helps with cell movement

• Regulates gene expression and contains DNA

• Stores water and nutrients

Which organelle is known as the 'powerhouse' of the cell?

• Nucleus

• Mitochondria

• Endoplasmic Reticulum

• Ribosome

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

• Cell division and replication

• Waste elimination and excretion

• Energy production and storage

• Protein and lipid synthesis, and transportation of molecules

What is the function of the lysosomes in a cell?

• Digestion of waste materials and cellular debris

• Storage of genetic information

• Production of energy for the cell

• Regulation of cell growth and division

What is the structure of the cell membrane?

• Single layer of phospholipids with no embedded proteins

• Protein bilayer with no cholesterol

• Phospholipid bilayer with embedded proteins and cholesterol

• Double layer of cholesterol with no embedded proteins

What are the functions of the ribosomes in a cell?

• DNA replication

• Energy production

• Protein synthesis

• Cell division

What is the function of the cytoplasm in a cell?

• It stores genetic information

• It provides a medium for the organelles to carry out their functions.

• It helps in cell movement

• It regulates the entry and exit of substances
