How do Plants get all that Energy?
Photosynthesis is the process by which green plants and some other organisms
use sunlight to synthesize food (in the form of glucose) and oxygen from carbon
dioxide and water.
1. __________________ + water + ___________  Glucose + ___________
Glucose is a simple sugar and is the most important form of energy to all life, plants and
animals.
So when a plant is in sunlight it is actively taking Carbon dioxide out of the air and
combining it with water molecules to make sugar molecules.
2. What molecule in the air is considered a greenhouse gas and is leading to global
warming?
3. Considering what you know about Photosynthesis why are trees so important in the
fight against global warming?
4. Look at the formula for photosyntheis why do you think that the plants that are in a
farmers field next to a road often do better than those that are far from the road?
Photosynthesis is a lot of work, in fact it is so much work that it can cause a plant to
sweat. The scientific name for a plant sweating is __________________________.
Just like us a plant must cool itself down when it is working hard. To do this the plant lets
water evaporate from its leaves.
5. Where does the water for transpiration come from?
6. How does photosynthesis and transpiration help to reduce landslides in rainforests??
Label the diagram to show that photosynthesis is occurring. Refer to the equation for
help.
