Cell Transport

 Look at the diagram of a cross-section of a cell membrane below. The cell membrane controls movement of materials into and out of the cell. The following particles are moving from high concentration to low concentration and are using a carrier protein. How would you describe this type of movement across the membrane? 

• simple osmosis
• active transport
• simple diffusion
• facilitated diffusion

Look at the cross section of a cell membrane of a eukaryotic cell. H+ ions are being pumped from a low concentration to a high concentration. How do you describe this type of transport across the cell membrane?

• active transport
• passive transport
• facilitated diffusion
• co-transport

The diagram below represents a cell and some molecules in its environment. Which molecule would require the use of energy in order to be brought into the cell?

• 1
• 2
• 3
• 4

The diffusion of water across a selectively permeable membrane is called 

• active transport
• facilitated diffusion
• osmosis
• phagocytosis

Cells need to bring in molecules to carry out cellular processes. Often, this requires moving the molecules across the cell membrane against the concentration gradient. How do these molecules get into the cell?

• passive transport by diffusion
• active transport using ATP 
• passive transport by osmosis
•  osmosis

The movement of molecules from an area of high concentration to an area of low concentration.

• Osmosis
• Respiration
• Diffusion
• Active Transport

Cells use energy to move materials across a membrane (low to high concentration).

• Active transport
• Passive transport
• Diffusion
• Osmosis
