Characteristics Of Living Things Practice Questions

1. True or False: The process of diffusion is a movement of molecules from an area of greater concentration to an area of lower concentration.

• True

• False

What is active transport?

• Active transport is when molecules move from a low concentration to a high concentration.

• Active transport is when molecules go from high concentration to a low concentration

• Active transport is the movement of water in and out of a cell.

• Active transport is when a cell shrivels.

Diffusion through a Membrane Lab

In the Diffusion Through a Membrane Lab, what was added to the inside of the artificial cell? Select all that apply.

• Glucose

• Starch Indicator (Iodine)

• Glucose Indicator

In the Diffusion Through a Membrane Lab, what was added to the outside of the artificial cell? Select all that apply.

• Starch

• Glucose

• Starch Indicator (Iodine)

• Glucose Indicator

In the Diffusion Through a Membrane Lab, why did the inside of the cell turn black?

• Glucose diffused out of the cell

• Starch diffused out of the cell

• Iodine (starch indicator) diffused into the cell

• Water diffused into the cell

A substance is most likely to diffuse into a cell when

• it is a large food molecule such as protein or starch

• it is enclosed in an organelle such as a vacuole

• the concentration of the substance is greater outside the cell than inside

• the concentration of the substance is greater inside the cell than outside

A red onion cell has undergone a change, as represented in the diagram below. This change is most likely due to the cell being placed in

• distilled water 

• salt water 

• light 

• darkness

In the Diffusion Through a Membrane Lab, which molecules were able to diffuse through the membrane? Select all that apply.

• Iodine (Starch Indicator)

• Starch

• Glucose

• Water

When both inside and outside of a cell have the same concentration of dissolved molecules it is said that the cell has reached a state of

• Osmosis

• Active transport

• Diffusion

• Equilibrium
