Exploring Photosynthesis and the Scientific Method

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.

Why is it important to have a control group in an experiment?

Back

A control group provides a baseline for comparison, helping to isolate the effects of the independent variable.

What is chlorophyll?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy for photosynthesis.
