- 1. Multiple ChoiceWhat a cell membrane is because it allows only certain substances to enter and leave a cellpermanentplasmasemipermeableflex wall
- 2. Multiple ChoiceThe movement of substances through a cell membrane without using the cell's energyosmosispassive transportactive transportdiffusion
- 3. Multiple ChoiceA flexible covering that protects the inside of a cell from the environment outside the cellCell MembraneExocytosisAerobic Respiration
- 4. Multiple ChoiceThe process during which a cell's vesicles release their contents outside the cellExocytosisEndocytosisOsmosis
- 5. Multiple ChoiceThe process during which a cell takes in a substance by surrounding it with the cell membraneEndocytosisExocytosisAnaerobic Respiration
- 6. Multiple ChoiceWhich of the following describes a state of equilibrium?When water molecules have stopped moving or vibratingWhen the concentration of water outside a cell is the same as the concentration of water inside a cellWhen a cell with a lot of water in it continues to absorb water
- 7. Multiple ChoiceThe cell membrane is semi-permeable. What does "permeable" mean?Extremely thickExtremely thinAble to be penetrated
- 8. Multiple ChoiceWhat is the difference between active and passive transport?Active transport requires energy; passive transport does notActive transport moves molecules across cell membranes; passive transport does notActive transport involves oxygen and water molecules; passive transport does not
- 9. Multiple ChoiceThe movement of substances from an area of higher concentration to an area of lower concentrationdiffusionosmosiscellular respiration
- 10. Multiple ChoiceThe movement of substances through a cell membrane only by using the cell's energyactive transportpassive transportendocytosis
- 11. Multiple ChoiceThe diffusion of water molecules only through a membranediffusionosmosisfacilitated diffusion
- 12. Multiple Choice
What process is shown in the image?endocytosisactive transportfacilitated diffusionexocytosis - 13. Multiple ChoiceWhy are there more dye particles in the right side of the membrane after 30 minutes?The membrane allowed active transport to take placehe membrane is not like a cell membrane, so the dye can get throughOnly dye particles could move through the membraneSome of the dye molecules diffused through the membrane
- 14. Multiple ChoiceWhat causes the dye particles to diffuse through the membrane?Particles move from an area of lower concentration to an area of higher concentrationParticles move from an area of higher concentration to an area of lower concentrationParticles move from an area of higher energy to an area of lower energy.Particles move from an area of lower energy to an area of higher energy
- 15. Multiple ChoiceWhat keeps cells from growing too large?If a cell gets too large, there is not enough energy available for active transportIf a cell gets too large, there is not enough energy available for active transportIf the surface-area-to-volume ratio is too small, not enough nutrients can move across the membrane.If a cell gets too large, there is not enough energy available for passive transport.
- 16. Multiple ChoicePassive transport requires energy.TrueFalse
- 17. Multiple ChoiceThis type of transport is passive. It uses a transport protein to help move materials across the cell membrane.diffusionosmosisfacilitated diffusionpumping
- 18. Multiple ChoiceThe movement of WATER across a selectively permeable without the use of energy is calledactive transportosmosisdiffusionendocytosis
- 19. Multiple ChoiceWhat is the job of a channel protein?strengthen the outer boundary of the cellallow certain materials to enter or leave the cellexchange organelles or chromosomes between cells
- 20. Multiple ChoiceWhich of the following are associated with movement across the cell membrane.diffusion and osmosis onlyactive transport onlyfacilitated diffusion onlydiffusion, osmosis, active transport, facilitated diffusion
