the start) and products (present atthe end) for the chemical reactioncalled photosynthesi

Photosynthesis is a chemical reaction that takes place in plants, algae, and some bacteria. Here's the process broken down:

Step 1: Absorption of Light The process of photosynthesis starts when the chlorophyll, a pigment in the plant cells, absorbs sunlight.

Step 2: Conversion of Light Energy to Chemical Energy The absorbed light energy is used to convert carbon dioxide and water, the reactants of photosynthesis, into glucose and oxygen.

Step 3: Release of Oxygen The oxygen produced during this reaction is released into the atmosphere.

Step 4: Use of Glucose The glucose produced is used by the plant for growth and energy.

So, the reactants (start) of photosynthesis are:

1. Carbon Dioxide (CO2)
2. Water (H2O)
3. Sunlight (energy)

The products (end) of photosynthesis are:

1. Glucose (C6H12O6)
2. Oxygen (O2)
