• Surface area to volume ratio

Which of the following will likely increase the rate of facilitated diffusion of a glucose molecule into the cell from the extracellular environment?

• Decreasing the concentration gradient
• Increasing the concentration gradient
• Decreasing the temperature
• Increasing the size of the glucose molecule

What is the process by which water molecules move from an area of lower concentration of solutes to an area of higher concentration of solutes through a semipermeable membrane?

• diffusion
• active transport
• filtration
• osmosis

What is the term used to describe the total concentration of solutes per liter of solution?

• concentration
• density
• tonicity

• osmolarity

What is the term used to describe the ability of a solution to affect the cell volume by changing the water content of the cell?

• concentration
• density
• tonicity

• osmolarity

Plant cells are more equipped to survive in a hypotonic environment. Which of the following is the reason for this?

• The chloroplasts in the plant cell slow down the accumulation of water by increasing its use during photosynthesis.

• The cell wall in the plant cell creates pressure against the intake of water and slows its movement into the cell.

• The mitochondria will increase their intake of water during cellular preparation toward the production of ATP molecules.

• The vacuole of the plant cell will continuously increase in size to accommodate the intake of water into the cell and allow the cell to maintain its shape.

All cells are made of ...

• flagellum, capsule, pili, plasmid

• plasma membrane, mitochondria, genetic material, chloroplast

• plasma membrane, cytoplasm, genetic material, ribosomes
