This is the text (if you need help).

Biologists have increased the size of crops by 20 per cent. They changed the how plants use photosynthesis. This is when plants use sunlight to change carbon dioxide into oxygen. The new plants use the energy from sunlight better. A professor said he is changing crops like rice, wheat, maize and soybean.

The scientists changed how plants keep safe in the Sun. Plants change energy into heat when they get hot. But, they also do this when it is cloudy. The scientists changed genes so plants can use more energy to grow. If crops can give 20 per cent more food, it will help us have more food in the future.
