Cellular Transport and Water Potential Insights

What is the main difference between passive and active transport?

• Passive transport requires energy, while active transport does not.

• Active transport moves materials from high to low concentration, while passive transport moves materials from low to high concentration.

• Passive transport does not require cellular energy, while active transport does.

• Active transport only occurs in animal cells, while passive transport only occurs in plant cells.

Which type of passive transport involves the random movement of particles from an area of high concentration to an area of low concentration?

• Simple diffusion

• Bulk transport

• Osmosis

• Facilitated diffusion

What is osmosis specifically the diffusion of?

• Proteins

• Solutes

• Water

• Gases

In facilitated diffusion, what helps specific materials pass through the cell membrane?

• Protein channels

• Lipid bilayer

• Carbohydrate chains

• Phospholipids

What is the role of protein pumps in active transport?

• They create a concentration gradient without using ATP.

• They force materials to move using cellular energy.

• They move materials from high to low concentration without energy.

• They facilitate the diffusion of water.

What does the term 'endocytosis' literally mean?

• Inside the cell process

• Cell eating process

• Out of the cell process

• Cell drinking process

Which process involves the cell ingesting liquid materials?

• Pinocytosis

• Phagocytosis

• Endocytosis

• Exocytosis

What is the Greek letter used to represent water potential?

• Psi

• Delta

• Beta

• Alpha

What happens to a plant cell when it is placed in pure water?

• It swells due to water intake.

• It remains unchanged.

• It shrinks due to water loss.

• It bursts due to excessive water intake.

How did the Romans use the concept of water potential to impact Carthage's agriculture?

• By adding salt to the soil to lower water potential.

• By removing all water sources.

• By flooding their fields with fresh water.

• By building dams to control water flow.
