Photosynthesis Foundation Worksheet

A greenhouse has a row of young plants. Use the information and visuals on this sheet to explain how photosynthesis helps them grow. Answer every question.

Photosynthesis at work

Plants make glucose, a type of sugar, by photosynthesis. In leaf cells, chlorophyll in chloroplasts absorbs light energy. The plant takes in carbon dioxide from the air and water from the soil. Glucose can be used for energy or growth. Oxygen is released into the air.

CARBON DIOXIDE from the air

WATER from the soil

LIGHT ENERGY from the Sun

GLUCOSE + OXYGEN made / released
