Cell Transport

What are the two types of cell transport?

• Passive and Active

• Active and Facilitated

• Passive and Facilitated

• None of the above

Which example describes diffusion?

• Water moving across a semi-permeable membrane

• Baking cookies and smelling them throughout the house

• Ions moving through an ion channel

• All of the above

What macromolecule is embedded into the lipid bilayer and helps to transport molecules?

• Carbohydrate

• Lipid

• Protein

• Nucleic Acid

Which describes a hypotonic environment?

• Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell

• Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell

• Concentrations of water are equal inside and outside the cell

Which describes a hypertonic environment?

• Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell

• Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell

• Concentrations of water are equal inside and outside the cell

Which describes an isotonic environment?

• Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell

• Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell

• Concentrations of water are equal inside and outside the cell
