Misconception<br />Many students do not understand that plants absorb carbon dioxide and water to produce organic materials.<br />Most of students have misconception that living organisms obtain energy by means other than by photosynthesis or food intake.<br />Students understand the need for water, air and sunlight by plants. But they fail to understand why these materials are important and how they are part of the production of ‘food’. <br />
