What is an autotroph?
An organism that is able to make its own food.
What part of the leaf absorb energy from the sun?
Chlorophyll
What do we call the process of by which plants produce sugar using energy from the sunlight?
Photosynthesis
What is the main source of energy for all living things?
Sun
Why is there a difference in the amount of oxygen produced by a plant exposed to light and a plant not exposed to light?
The plant exposed to light is able to carry out photosynthesis while the plant not exposed to light is unable to carry out photosynthesis.
How many molecules of carbon dioxide and water are needed for photosynthesis to occur?
6
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 energy
What are the products of photosynthesis?
Glucose and oxygen
In which organelle does photosynthesis take place?
Chloroplast
What two components of photosynthesis are constantly being exchanged between plants and animals?
carbon dioxide and oxygen
How would a cloudy day affect photosynthesis?
There would be less photosynthesis because there would be less sunlight.
What type of reaction is photosynthesis?
Chemical Reaction
What part of the leaf is an opening that allows for the exchange of gases?
Stomata
What are the reactants of photosynthesis?
Carbon dioxide, water, radiant energy
What is a heterotroph?
An organism that does not make its own food and has to eat to get energy.
What part of the plant gets the water needed for photosynthesis?
Roots
What happens to the radiant energy during photosynthesis?
It is converted to potential energy in the form of glucose
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.
