Which statement best explains why gas transport takes place as represented in the diagram below?

• The carbon dioxide concentration is greater in the cells than in the environment.

• The carbon dioxide is absorbed into the environment though active transport

• The carbon dioxide concentration in the cells is equal to that in the environment.

• The carbon dioxide is is transported to the environment by a transport system.

A biologist observed a plant cell in a drop of water and illustrated it as in diagram A. He added a 10% salt solution to the slide, observed the cell, and illustrated it as in diagram. The change in appearance of the cell resulted from more

• Salt flowing out of the cell than into the cell

• salf flowing into the cell than out of the cell

• water flowing into the cell than out of the cell

• Water flowing out of the cell than into the cell

If the external environment of a living cell has a greater concentration of salt than the cytoplasm within the cell, the cell will tend to

• divide

• increase its size

• lose water

• excrete salt

• Osmosis

Which process utilizes cellular energy to move particles through a membrane?

• active transport

• transpiration

• Osmosis

• Passive transport

Since cyanide is a poison that limits a cell's ability to manufacture ATP, a cell containing cyanide is least likely to carry on the process of

The net flow of materials through the membrane of a cell against a concentration gradient is known as

• active transport

• circulation

• transpiration

Water and minerals move from the soil into a plant by the process of

• diffusion, only

• active transport, only

• passive transport and hydrolysis

• both diffusion and active transport

Red blood cells contain a higher concentration of potassium than the surrounding blood plasma does. This higher concentration is maintained by the process of

• osmosis

• simple diffusion

• active transport
