Transport in Cells

This picture represents what type of cell transport?

• exocytosis

• osmosis

• passive transport

Osmosis is the movement of _____ across a membrane.

• food

• energy

• oxygen

• water

The concentration of water is higher in the soil than in plant root cells. Water moves into root cells of a plant by...

• Facilitated Diffusion

• Simple Diffusion

• Active Transport

• Osmosis

In a nerve cell, ATP energy is used to pump sodium (Na) out of the cell and potassium (K) into the cell. This is an example of...

• Facilitated Diffusion

• Simple Diffusion

A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?

• The swollen gums have absorbed the saltwater solution.

• The saltwater solution lowers the temperature of the water in the gums.

• The salt in the solution has moved against the concentration gradient.

• The water in the gums has moved out due to the high concentration of salt in the solution.

 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

Which activity can occur without the use of energy?

• contraction of muscle tissue
• protein synthesis in a cell
• active transport of minerals
• movement of water across a membrane
