What is photosynthesis?

• Photosynthesis is the process by which green plants convert sunlight into heat energy.

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

• Photosynthesis is the process of breaking down glucose to release energy in plants.

• Photosynthesis is the process by which animals convert food into energy.

What part of the plant absorbs water?

• The leaves of the plant

• The stems of the plant

• The roots of the plant

• The flowers of the plant

What happens to carbon dioxide during photosynthesis?

• Carbon dioxide is absorbed by plants and used to produce glucose.

• Carbon dioxide is released into the atmosphere as a waste product.

• Carbon dioxide is converted into oxygen and water.

• Carbon dioxide is stored in the soil for later use.

What gives plants their green color?

• Chlorophyll

• Carotene

• Xanthophyll

• Anthocyanin

What do plants need for photosynthesis?
