What are the reactants of photosynthesis?
Carbon dioxide, water, radiant energy
What are the products of photosynthesis?
Glucose and oxygen
In which organelle does photosynthesis take place?
Chloroplast
What part of the leaf absorb energy from the sun?
Chlorophyll
What part of the leaf is an opening that allows for the exchange of gases?
Stomata
How many molecules of carbon dioxide and water are needed for photosynthesis to occur?
6
What is the main source of energy for all living things?
Sun
What do we call the process of by which plants produce sugar using energy from the sunlight?
Photosynthesis
What is an autotroph?
An organism that is able to make its own food.
What is a heterotroph?
An organism that does not make its own food and has to eat to get energy.
What type of reaction is photosynthesis?
Chemical Reaction
What part of the plant gets the water needed for photosynthesis?
Roots
How would a cloudy day affect photosynthesis?
There would be less photosynthesis because there would be less sunlight.
What would happen if a plant were placed in a clear tank full of carbon dioxide?
More photosynthesis would occur. Eventually the carbon dioxide would be replaced with oxygen.
True or False: only some of the reactants show up as products, the rest just disappear.
False: all of the reactants rearrange to form all of the products.
What do we call the type of energy from the sun that is used in photosynthesis?
Radiant/Solar energy
