Cell Transport 5B

When a cell uses energy to transport ions against the concentration gradient _________ is used.

• active transport
• passive transport
• diffusion
• osmosis

Which of the following substances would cross the cell membrane using facilitated diffusion?

• sugar molecule
• water
• sodium ions
• calcium ions

Predict what would happen to a cell that was placed in a hypertonic solution.

• the cell would shrivel
• the cell would expand
• the cell would remain the same

The movement of water down a concentration gradient within the cell is called?

• diffusion
• osmosis

In what direction will water move in a cell placed into a hypotonic solution?

• out of the cell
• into the cell
• net movement will equal zero

In what direction will water move if the cell is placed into an isotonic solution?

• into the cell
• out of the cell
• net movement will equal zero

Which cell process is shown in the image?

• endocytosis

• exocytosis

• osmosis

• diffusion

Which is an example of an active transport process?

• carrier proteins to move ions with concentration gradient
• the sodium-potassium pump
• the movement of water into and out of the cell
• diffusion through ion channels

Cell begin bursting when placed in a solution. The solution is likely _______.

• hypertonic
• hypotonic
• isotonic

Which process is used by cells to remove wastes?

• endocytosis
• exocytosis
