Unit 2 Cells and Transport 22-23

If the water molecule concentration outside the cell is higher than the inside of the cell this is called a __________________ solution.

• Hypotonic

• Hypertonic

• Isotonic

• Nisotonic

Which of the following terms means that the cell is in equilibrium to the environment?

• Hypotonic

• Hypertonic

• Isotonic

• Badotonic

I dropped a red blood cell in to isotonic solution and it stays the same. What would happen if I added sugar into the water to make the cell a hypertonic solution?

• Water would rush into the cell making is swell

• Water would be released from the cell making is shrink/shrivel

• The cell would remain the same size

• The cell would get a toothache because of all of the sugar.

What is the image showing?

• Endocytosis, active transport

• Endocytosis passive transport

• Exocytosis, active transport

• Exocytosis, passive transport

What is the image showing?

• Endocytosis, active transport

• Endocytosis passive transport

• Exocytosis, active transport

• Exocytosis, passive transport

The image shows a beaker having red dye added to it. Explain what is happening in the beaker.

• The red dye moved by diffusion(higher concentration to a lower concentration)

• The red dye moved by active transport (higher concentration to a lower concentration)

• The red dye moved by osmosis(higher concentration to a lower concentration)

• The red dye moved by exocytosis(higher concentration to a lower concentration)

Active transport requires energy because...

• It goes down the concentration gradient (high to low)

• The cell membrane is super thick.

• Its lazy and cannot stand working.

• It goes against the concentration gradient (low to high)

The circle in the middle is a bag that only lets water move in and out of it. What would you expect to happen?

• The balloon will gain water due to it being hypertonic to the solution; done by osmosis

• The balloon will lose water due to it being hypertonic to the solution; done by osmosis

• The balloon will gain water due to it being hypertonic to the solution; done by exocytosis

• The balloon will gain water due to it being hypertonic to the solution; done by endocytosis
