Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

What do plants use glucose (sugar) for?

Back

Plants use glucose for energy, growth, making new cells, and producing seeds and flowers. It can also be stored for later use.

What is the function of the vacuole in plant cells?

Back

The vacuole stores water and helps maintain turgor pressure in plant cells, which is important for photosynthesis.

How does light intensity affect the rate of photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis, up to a certain point, after which it may plateau.

What happens to the rate of photosynthesis if the daylight hours are reduced?

Back

Reducing daylight hours decreases the rate of photosynthesis because plants require light to produce glucose.
