Photsynthesis Flashcards
What is photosynthesis?
Chemical reaction in which energy is transferred from the light from the sun to the leaves of the plant.
What is Chlorophyll?
The green pigment inside chloroplasts in the leaves that absorb light energy.
What is a limiting factor?
A limiting factor is anything that limits the rate of reaction when it is in short reply.
What are the limiting factors of photosynthesis?
- temperature
- Carbon dioxide concentration
- light intensity
- Amount of chlorophyll
What is the word equation for photosynthesis?
Carbon dioxide + water –> glucose + oxygen
What is the chemical formula for photosynthesis?
6CO² + 6H²O –> C6H15O6 + 6O²
Enzyme-controlled reaction
What happens to the rate of reaction (photosynthesis) When temperature gets to high?
The enzymes denature and the reaction stops
What happens to the photosynthesis reaction as the concentration of carbon dioxide increases?
Another factor becomes limiting
What happens to the photosynthesis reaction as the light intesity increases?
- Photosynthesis is needed for the reaction
- Another factor becomes limiting
What is the inverse square law?
Light intesity = 1 / Distance²
What are the uses of Glucose produced in photosynthesis?
- For respiration
- Cellulose to strengthen cell walls
- Converted into insoluble starch for storage
- Produce fat or oil for storage
- Produce amino acids for protein synthesis
