Photosynthesis, Cellular Respiration, Diffusion, Osmosis Review

Front

What is diffusion?

Back

Diffusion is the process where molecules move from a high concentration to a low concentration.

Front

What happens to cells when a person drinks salty water?

Back

The cells would shrink or dehydrate.

Front

What happens to the cell wall and cell membrane in plant cells when they lose water?

Back

The cell wall stays the same, but the cell membrane shrinks.

Front

Where is there a low concentration of dye in a cup?

Back

At the bottom of the cup.

Front

What happens to cells if pure water is put into their veins?

Back

The cells would expand or explode.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a semi-permeable membrane from a low concentration of solute to a high concentration of solute.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs sunlight for photosynthesis.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move molecules against their concentration gradient, while passive transport does not.
