Photosynthesis

Front

What are the products of photosynthesis?

Back

Oxygen and sugar (glucose)

Front

How does carbon dioxide enter the leaves of a plant?

Back

It enters through the stomata.

Front

How does most of the water needed by the plant get into its leaves?

Back

The roots absorb it and then it travels up the xylem.

Front

What happens to the rate of photosynthesis when light intensity increases?

Back

The rate of photosynthesis goes up.

Front

What are the three key ingredients needed for photosynthesis?

Back

Sunlight, water, and carbon dioxide.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, to convert carbon dioxide and water into glucose and oxygen.

Front

What is the overall chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What is the significance of stomata in photosynthesis?

Back

Stomata are small openings on the leaf surface that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit.

Front

What is the function of xylem in plants?

Back

Xylem transports water and dissolved minerals from the roots to the rest of the plant.

Front

How does temperature affect the rate of photosynthesis?

Back

As temperature increases, the rate of photosynthesis generally increases up to a certain point, after which it may decline.
