Ms. Clark is teaching her class about how plants make food for themselves. On the board, she has written this:

Photosynthesis is used to produce food for plants in the form of glucose. In the process, oxygen is released. As shown in the diagram, plants require water and carbon dioxide (from the air). What else is required for photosynthesis and what role does it play?

• ATP is required as an energy source for photosynthesis.

• Light is required to provide energy for photosynthesis.

• Glucose is required as an energy source for photosynthesis

• Oxygen is required to split water molecules in photosynthesis.

Photosynthesis is used to produce food for plants. Plants are called autotrophs because they produce their own food. Animals are heterotrophs, meaning they eat their food. What do plants produce in photosynthesis that is used by animals and other heterotrophs?

• glucose only

• glucose and oxygen

• glucose and carbon dioxide

• oxygen only

Which would have the GREATEST effect on the rate of photosynthesis in a plant?

• sugar concentration

• light intensity

• oxygen level

Photosynthesis

• A membrane-bound organelle in eukaryotic cells that contains the DNA; the control center of the cell

• A structure inside a cell that performs a specialized function

• A chemical reaction during which plants convert radiant energy from the Sun to chemical energy; the reaction converts carbon dioxide and water into sugar (glucose) and oxygen

• The organelle that stores water and food in both plant and animal cells
