Photosynthesis is the process by which plants convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.

Photosynthesis occurs only at night when plants release carbon dioxide.

Photosynthesis is the process of plants absorbing nutrients from the soil.

Photosynthesis is the method by which plants decompose organic matter.
