Cell Transport Review Quiz

What process occurs when WATER diffuses across a membrane?

• endocytosis
• mitosis
• osmosis
• nuclear fission 

What does “high concentration area” mean?

• Spread out
• Tightly packed together
• Uncrowded
• Spacious

When particles move from areas of high concentration to areas less concentrated, this has taken place.

• diffusion
• mitosis
• endocytosis
• photosynthesis

What does selectively-permeable mean?

• The cell controls what passes in and out of the cell
• Nothing gets through
• The cell lets only large substances through

What is the definition of LIPID BILAYER?

• Molecular structure that surrounds the cell and controls what enters and leaves the cell

• Movement of molecules across the cell membrane against the concentration gradient

• Diffusion of water through a selectively permeable membrane

• Movement of molecules across the cell membrane from an area of high concentration to low concentration
