Cell Transport

The diffusion of water across a selectively permeable membrane is called 

• active transport
• facilitated diffusion
• osmosis
• phagocytosis

The process where only water is allowed to pass through the cell membrane from a high to low concentration.

• meiosis
• respiration
• diffusion
• 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

Cells transport material across a cell membrane without using energy (high to low concentration)

• Passive transport
• Concentration
• Endocytosis
• Active Transport

Which of the following is an example of osmosis?

• Oxygen exiting leaves after photosynthesis
• A raisin swelling in a cup of water
• Water changing from a liquid to a gas
• Oxygen moving into an animal cell

What are the two types of cell transport?

• Passive and Active

• Active and Facilitated

• Passive and Facilitated

• None of the above

In passive transport, substances move across the cell membrane ________ the concentration gradient

• AGAINST

• ALONG

• WITH

• BETWEEN

Which describes a hypotonic environment?

• Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell

• Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell

• Concentrations of water are equal inside and outside the cell

Which describes a hypertonic environment?

• Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell

• Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell

• Concentrations of water are equal inside and outside the cell
