Flashcard Set 3: Photosynthesis and Food Production
What is photosynthesis?
Photosynthesis is the process by which green plants make their own food using sunlight, carbon dioxide, and water.
Write the word equation for photosynthesis.
Carbon dioxide + Water → Glucose + Oxygen (in the presence of sunlight and chlorophyll).
What is chlorophyll and where is it found?
Chlorophyll is a green pigment found in chloroplasts of plant cells; it absorbs sunlight for photosynthesis.
What is the importance of photosynthesis in ecosystems?
Photosynthesis produces oxygen and is the base of energy for almost all life forms.
Name two factors that affect the rate of photosynthesis.
Light intensity and carbon dioxide concentration.
What is a test for photosynthesis in a plant?
The starch test, where iodine turns blue-black in the presence of starch, indicates photosynthesis.
