• Gravity

• Osmosis

• Magnetism

• Inertia

Which cellular structure is responsible for regulating the movement of substances into and out the cell?

• Ribosome

• Nucleus

• Cell membrane

• Mitochondria

Why is substance movement necessary for cells?

• To generate energy

• To maintain homeostasis

• To produce proteins

• To store genetic information

Which of the following is a passive mode of substances movement across a cell membrane?

• Phospholipids

• Proteins

• Nucleic acids

• Cholesterol

What does selectively permeable mean in the context of cell membrane?

• Allows all the substances to pass through

• Allows only certain substances to pass through

• Prevents all substances from passing through

• Allows only water to pass through

Which substance is commonly involved in osmosis?

• Oxygen

• Glucose

• Water

• Carbon dioxide

What is the role of transport proteins in the cell membrane?

• Energy production

• Facilitate movement of substances across the membrane

• Store genetic information

• Synthesize lipids
