Cell Processes

What is diffusion?

• when molecules move from a low concentration to a high concentration 
• when molecules move from a high concentration to a low concentration.
• no movement 
• molecules move everywhere

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

What is the definition of Osmosis?

• the movement of WATER molecules across the cell membrane.
  
• the state where molecules are equally concentrated (balanced) on both sides of the cell membrane.
  
• the process that brings LARGE particles INTO the cell through the cell membrane
  
• he movement of molecules across the cell membrane that REQUIRES ENERGY output from the cell
  

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar
• CO₂ + sugar + H₂O --> O₂ + light
• _O2 + light + H₂O --> CO₂ + Sugar
• CO₂ + O₂ + H₂O --> Light+ Sugar

What process occurs when light energy is captured in autotrophs and converted into sugar?
