Unit 1 Intervention (Part B Transport)

Match the following processes of Active Transport

Each category has 2 characteristics.

A student prepared four different blood cell suspensions, as shown in the chart below.

Note: Distilled water is water that has been boiled until it completely vaporizes, after which the water vapor is condensed back to liquid water. Distilled water is free from all organic and inorganic impurities and microorganisms, as they are completely removed during distillation. However, tap water contains high concentrations of ions, minerals, and other solutes.

Which of the solutions is MOST likely to cause the red blood cell to swell?

Refer to the picture below of the cell membrane. Certain molecules must travel through this structure when they are large and/or polar. Which macromolecule makes up the blue "channel" shown?

As part of a science class, a group of students went on a field trip to a nearby pond where they collected samples of pond water and a sample of a pond plant. The students used a microscope to study the cells within their samples and also a sample of their own cheek cells. Their observations are recorded in the table below.

According to the table, which pond organism was an animal?

An osmosis investigation was conducted using chicken eggs to represent cells with semipermeable membranes. The mass of each egg was measured to determine how much water diffused into or out of the eggs. The eggs were first soaked in vinegar to dissolve the shell. Each egg was then placed in one of three different solutions for 24 hours. The table below shows the results of the investigation.

Based on this experiment, which of the following should be inferred about cells with semipermeable membranes?

Low water concentration means

Water moves to areas with ________ solute concentrations

Which one is the low solute concentration?

The cells are hypertonic because they have a _______ concentration of solutes.

Which type of solution is given to people in the hospital who need "fluids"?

If the root hair cells have a HIGHER solute concentration than that of the soil, this means they are

All living organisms depend on osmosis for the movement of

The principal force driving movement in diffusion is the __________.

Eventually the two sides will come to equilibrium which is when the concentration of particles are equal on both sides.

Diffusion always moves solutes/particles from

The difference between facilitated diffusion and regular (simple) diffusion is that facilitated diffusion

Which temperature yields faster movement of diffusion?

What happens to the movement of molecules when the temperature is raised? (red food coloring demo)

What happens to the movement of molecules when their temperature is lowered? (blue food coloring demo)

When sugar is mixed with water, equilibrium is reached when

The rate of diffusion is affected by which of the following? Select all that apply.

The molecules in a solid lump of sugar do not move.
