Photosynthesis Test- Restivo
Plants use sunlight to make their own food, a type of _________
sugar
What happens to the light energy from the sun when it hits the plant?
It is absorbed by the plant, and then is transformed into chemical energy
How many elements are needed for a plant to create glucose?
3
What is a pigment?
A specialized molecule that can absorb or reflect light
During photosynthesis, plants take simple materials and recombine them into glucose. Why do you think glucose is considered "energy rich?"
Because during photosynthesis, light energy is converted into chemical energy which is stored in glucose.
In the _____ , light energy breaks up __________ and water molecules, and they are recombined to create _________ molecules.
Carbon dioxide, Glucose
Light energy is converted into what type of energy during photosynthesis?
Chemical Energy
When a rabbit eats the plant, what kind of energy is transferred from the plant to the rabbit?
Chemical Energy
Chloroplast contain green pigments called ___________
Chlorophylls
Describe the energy transformation during photosynthesis?
During photosynthesis, light energy is transformed into chemical energy.
What can glucose be used for?
Glucose is used as the main source of energy in the plant.
Plants transform these three elements (water, sunlight, carbon dioxide) into a form of sugar called _______. The sugars plants create in their leaves give plants ______ to live and grow.
Glucose, Energy
Where is the glucose made?
In the Chloroplast.
What kind of energy from the sun is absorbed by the chloroplast?
Light energy
What do plants release during photosynthesis?
Oxygen
What does Photosynthesis mean literally?
Photosynthesis is made from photo (light) and synthesis (combine/put together). So photosynthesis means putting together using light.
Describe a Chlorplast
Place where plants convert light energy to chemical energy A type of organelle.
Where do plants get energy to grow?
Plants get light energy from the sun to grow.
What is the energy that the sun gives off called?
Solar radiation/light energy
What does the Chlorophyll do?
This captures light energy for photosynthesis.
What happens to energy from the sun when it reaches green plants?
What happens to energy from the sun when it reaches green plants?
chloroplasts transform _________ into chemical energy and stored chemical energy in sugar molecules.
light energy from the sun
A process of turning three elements into sugar is called _________. During this process, plants also release , ________, a gas needed by all living things.
photosynthesis, oxygen
What is photosynthesis?
the process by which plants use the energy from sunlight to make sugars.. Photosynthesis is the process by which plants use light energy from the sun to make sugars.
In order to produce their own food, plants need three things: sunlight,______ and ________ from the air.
water, carbon dioxide
What happens to light energy from the sun when it REACHES earth?
It is transformed
What do plants need to make their own food?
