Photosynthesis

Photosynthesis Equation:

The overall balanced equation for photosynthesis is:

$$\text{Carbon dioxide} + \text{Water} \xrightarrow{\text{Light Energy}} \text{Glucose} + \text{Oxygen}$$

In chemical symbols:

$$\text{CO}_2 + 6\text{H}_2\text{O} \xrightarrow{\text{Light Energy}} \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2$$

• Carbon Dioxide: CO₂
• Water: H₂O
• Glucose: C₆H₁₂O₆
• Oxygen: O₂

Plants can make their own food

Happens in the chloroplasts: Contain chlorophyll which absorb light (energy)

Photosynthetic organisms are the main producers of food for the earth

Photosynthetic organisms such as green plants & algae use energy from the sun to make glucose ⬇️

Some of the glucose is used to make larger complex molecules that the plant needs to grow (made of the organisms biomass)

⬇️

The energy stored in the organism's biomass then works its way through the food chain as animals eat them & each other

Endothermic reaction

• Energy is taken in during the reaction
