Photosynthesis Definition
Photosynthesis transforms carbon dioxide and water into sugar and oxygen using energy from the Sun. For example, plants produce their own food and release oxygen through this process.

Photosynthesis & Respiration
Fun Facts
- Cyanobacteria and algae go through the process of photosynthesis.
- Half of Earth's oxygen comes from oceanic cyanobacteria and plankton.
- Since humans need energy for everything we do, we can harness photosynthesis to make chemical or electrical energy.
Why Do We Need To Know About Photosynthesis
Learning about photosynthesis helps us understand how plants make their food and why it’s important for our planet and future technology. Scientists study photosynthesis to try and use its power to make renewable energy better. They want to create better solar panels and biofuels, which are fuels made from plant materials, so we don’t have to rely so much on oil and gas.
This kind of research can lead to jobs in fields like biology, biotech, and renewable energy. It shows us how studying plants can help us find new ways to make energy. By doing experiments, like watching small pieces of leaves make oxygen in water, students can see how photosynthesis can help make biofuels and improve solar energy.
