Photosynthesis Flashcards
How does energy enter the ecosystem?
Sunlight
Plants use the sun’s energy to make?
Glucose
The sun’s energy is stored if the form of what molecule?
glucose
Photosynthesis is converting ______ energy from the sun into chemical energy from glucose.
Radical Energy
Photosynthesis is converting radical energy from the sun into ________ energy from glucose.
Chemical Energy
What do two elements do plants convert into glucose?
water and carbon dioxide
What is waste product of photosynthesis?
Oxygen
Life on Earth is dependent on photosynthesis for ____
food and oxygen
What is the equation for photosythesis?
6 CO2 (carbon dioxide) + 6 H20 (water) + sunlight –> C6H12O6 (glucose) + 6 O2 (oxygen)
Where is carbon dioxide found?
atmosphere
What takes in carbon dioxide?
leaves
What is a stomata?
tiny cell on leaf of plant required for photosythesis
What has a double membrane?
Chloroplast
