Cells and cell transport Review

___ is particle movement from an area of lower concentration to an area of higher concentration.

• Active transport

• Passive transport

Which type of passive transport focuses on the movement of water through the membrane?

• Facilitated diffusion

• Osmosis

• Diffusion

What term describes a solution that has the same solute concentration inside of and outside of the cell?

• Hypertonic

• Hypotonic

• Isotonic

The cell shrunk in size, which means it was placed in a ____ solution.

• Isotonic

• Hypertonic

• Hypotonic

Active transport requires energy because...

• The cell is moving something against a concentration gradient

• The cell is moving something with a concentration gradient

What part of the cell regulates what can enter and leave the cell?  

• Cell Membrane

• Nucleus

• Mitochondria

• Cytoplasm

The picture below is an example of _________________.

• osmosis

• isotonic

• diffusion

• active transport

Students are observing particles moving with the concentration gradient in a lab investigation. Which type of transport are they observing?

• using pumps to move things quickly

• passive transport

• osmosis

• endocytosis

The cell membrane is responsible for allowing molecules to diffuse through a protein channel, from high concentration to low concentration. What type of transport is this?

• Passive Transport

• Active transport

The cell membrane needs to use energy to move molecules quickly out of the cell through a pump. What type of transport is this?

• Passive transport

• Active transport
