Cell Transport Quiz

This picture represents what type of cell transport?

• Endocytosis
• Osmosis
• Exocytosis
• Passive Transport

Osmosis is the movement of _________ across a membrane.

• Food
• Oxygen
• Energy
• Water

Which is true about active transport?

• It requires energy
• It moves substances down the concentration gradient
• It does not require energy
• It moves material from high to low concentration

The concentration of water is higher in the soil than in plant root cells. Which way will the water move?

• Into the plant root cells
• Out of the plant root cells
• In and out of the plant root cells equally

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
• Active Transport
• Simple Diffusion
• Osmosis

Large food molecules are moved into a cell by the process of _______________

• Endocytosis
• Exocytosis
• Diffusion
• Osmosis

Cell membranes are said to be selectively permeable. Which statement best explains what selectively permeable means?

• The cell membrane allows only large molecules to diffuse into the cell.
• The cell membrane prevents any harmful substances from entering the cell.
• The cell membrane lets certain substances enter the cell and keeps certain substances out of the cell.
• The cell membrane has pores that let only water and glucose into the cell and carbon dioxide out of the cell.

The solution outside of a cell is 70% salt. The inside of the cell is 90% salt. What will happen to the cell?

• Water will move into the cell
• Water will move out of the cell.
• Salt will move into the cell.
• Salt will move out of the cell.

The solution outside of a cell is 70% salt. The inside of the cell is 90% salt. What kind of solution is the cell in?

• Hypertonic
• Hypotonic
• Isotonic
• There is not enough information to determine.

Some inquisitive students found two slugs and wanted to take them to science class. The only container they could find was a used potato chip bag. The students stored the slugs in the bag to take to school the next day, When the students opened the bag at school, they found that the slugs had melted and turned to slime. Explain why this happen?

• The slugs had an defensive reaction to the salt, and the slime was a response to that reaction.
• The salt around the slugs created a hypotonic environment, which caused water to diffuse into cells and made them undergo cytolysis.
• The salt around the slugs created a hypertonic environment, which caused water to diffuse out of cells and the cells will shrink.
• The salt around the slugs created an isotonic environment, which caused water to diffuse out of and into the cells which made the slugs melt.
