Unit 2 bio quiz

what is active transport

• Active transport is the movement of substances with their concentration gradient, requiring no energy.
• Energy-requiring process that moves material across a cell membrane against a concentration gradient

• Active transport is the passive movement of water across a membrane.
• Active transport is the process of diffusion that does not require energy.

what is a concentration gradient

• A concentration gradient is the difference in concentration of a substance between two areas.
• A concentration gradient is the process of mixing two substances.
• A concentration gradient only occurs in gases.
• A concentration gradient is the same throughout a solution.

what is diffusion

• Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
• Diffusion refers to the mixing of two substances in equal proportions.
• Diffusion is the transfer of energy from one particle to another.
• Diffusion is the process of particles moving randomly without any concentration gradient.

what is endocytosis

what is exocytosis

• Exocytosis is the absorption of nutrients by cells.
• Exocytosis is the process by which cells expel materials by vesicle fusion with the plasma membrane.
• Exocytosis is the process of cell division.
• Exocytosis is the method by which cells take in water.

what is facilitated diffusion

• Facilitated diffusion requires energy input to function.
• Facilitated diffusion is a type of active transport that moves molecules against their concentration gradient.
• Facilitated diffusion only occurs in plant cells.
• Facilitated diffusion is a type of passive transport that uses transport proteins to move molecules across a cell membrane.

hypertonic solution

• A solution that has equal concentrations of solutes compared to another solution.
• A solution with a lower concentration of solutes than another solution.
• A solution that contains no solutes at all.
• A solution in which the concentration of solutes is greater than that of the cell that resides in the solution

hypotonic solution

• A solution that has the same concentration of solutes as another solution.
• 
  

  A solution in which the concentration of solutes is less than that of the cell that resides in the solution

• A solution that contains no solutes at all.
• A solution with a higher concentration of solutes than another solution.
