Cell Membrane and Transport Quiz

What is the function of the cell membrane?

• Regulates cell division

• Controls the movement of materials in and out of the cell

• Produces energy for the cell

• Stores genetic information

What does it mean for the cell membrane to be semi-permeable/selectively permeable?

• It allows all materials to enter or leave the cell

• It allows only certain materials to enter or leave the cell

• It allows no materials to enter or leave the cell

• It allows materials to enter or leave the cell randomly

What is the definition of high concentration?

• Random distribution of materials

• Equal concentrations of materials

• Crowded, many materials in a given space

• Less crowded, not many materials in a given space

What is the definition of low concentration?

• Equal concentrations of materials

• Random distribution of materials

• Less crowded, not many materials in a given space

• Crowded, many materials in a given space

What is the state most materials want to reach?

• Selective permeability

• High concentration

• Equilibrium

• Low concentration

What is the process of diffusion?

• The movement of water from areas of low concentration to areas of high concentration

• The movement of water from areas of high concentration to areas of low concentration

• The movement of small materials from areas of high concentration to areas of low concentration

• The movement of small materials from areas of low concentration to areas of high concentration

What is the process of osmosis?

• The movement of water from areas of low concentration to areas of high concentration

• The movement of small materials from areas of high concentration to areas of low concentration

• The movement of small materials from areas of low concentration to areas of high concentration

• The movement of water from areas of high concentration to areas of low concentration

What is the process of facilitated diffusion?

• The movement of larger materials from areas of low concentration to areas of high concentration

• The movement of water from areas of low concentration to areas of high concentration

• The movement of larger materials from areas of high concentration to areas of low concentration

• The movement of water from areas of high concentration to areas of low concentration

What is the process of active transport?

• The movement of materials, without using energy, from areas of low concentration to areas of high concentration

• The movement of materials, using energy, from areas of high concentration to areas of low concentration

• The movement of materials, without using energy, from areas of high concentration to areas of low concentration

• The movement of materials, using energy, from areas of low concentration to areas of high concentration

What is the process of endocytosis?

• The passive process by which a cell releases a particle in a vesicle, after the vesicle fuses to the cell membrane

• The active process by which a cell membrane surrounds a particle and encloses it in a vesicle to bring it into the cell

• The active process by which a cell releases a particle in a vesicle, after the vesicle fuses to the cell membrane

• The passive process by which a cell membrane surrounds a particle and encloses it in a vesicle to bring it into the cell
