LIFE SCIENCE

Detailed explanation-1: -During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Detailed explanation-2: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-3: -Photosynthesis can be split into two processes. The “photo” part refers to reactions triggered by light. “Synthesis”-the making of the sugar-is a separate process called the Calvin cycle.

Detailed explanation-4: -Background Information: Plants make sugar by using energy from sunlight to transform carbon dioxide (CO2), a gas absorbed from the air, and water (H20) taken from the ground by roots into glucose (C6H12O6) and oxygen (O2). This process is called photosynthesis and occurs in the chloroplast of the plant cell.
