Cell Transport Quiz

What does the term "homeostasis" refer to in cellular biology?

• The process of cell division

• The movement of water into the cell

• The balanced condition regulated by the cell membrane

• The release of energy from the cell

What characterizes passive transport across a cell membrane?

• Movement from low to high concentration using energy

• Movement from high to low concentration without using energy

• Movement of water out of the cell

• Active transport of ions into the cell

Which process describes active transport in cells?

• Movement from high to low concentration without energy

• Diffusion of gases through the cell membrane

• Movement from low to high concentration using ATP (energy)

• Natural osmosis without energy expenditure

What happens to a cell in a hypotonic solution?

• The cell shrinks as water moves out

• The cell remains the same size, balancing water intake and output

• The cell swells as water moves into it

• The cell divides due to pressure

What occurs in a hypertonic solution?

• The cell swells as water moves into it

• The cell shrinks as water moves out

• The cell maintains equilibrium with no size change

• The cell increases nutrient absorption

What term is used to describe the process by which organisms maintain a stable internal environment?

• Adaptation

• Homeostasis

• Metabolism

• Respiration

What is the cell membrane also known as?

• Cytoplasmic Membrane

• Plasma Membrane

• Nuclear Membrane

• Mitochondrial Membrane

Which of the following is NOT a function of the cell membrane?

• Regulating transport in and out of the cell

• Acting as a barrier

• Surrounding all cell organelles

• Surrounding all cells

What component of the cell membrane is primarily made up of phospholipids?

• Lipid bilayer

• Protein channels

• Carbohydrate chains

• Cholesterol

Which biomolecule is not found in the cell membrane?

• Proteins
