Photosynthesis and Limiting Factors Flashcards
What is photosynthesis?
Photosynthesis is the process by which plants use energy to change carbon dioxide and water into glucose and oxygen
Where in the plant does photosynthesis take place?
In the chloroplasts, they contain chlorophyll which absorbs light
Is photosynthesis exo or endothermic
Endothermic this means energy is transferred from the environment in the process
What is the word equation for photosynthesis?
Carbon Dioxide + Water __l_i_g_h_t___> glucose + oxygen
What is the symbol equation for Photosynthesis?
6CO2 + 6H20 __l_i_g_h_t___> C6H12O6 + 6O2
What five ways do plants use Glucose?
- For respiration
- Making Cellulose
- Making Amino Acids
- Storws as oils or fats
- Stored as starch
What is Cellulose used for?
Making strong cell walls
What is glucose combined with to form amino acids?
Glucose is formed with nitrate ions to form amino acids which are then made into proteins
How is Glucose stored as oils or fats
Glucose is turned into Lipids which are stored in seeds
Why is Glucose stored as Starch?
It is stored as starch for when photosynthesis isn’t happening, like in the winter when there is limited sunlight and cold temperatures
What main limiting factors affect the rate of Photosynthesis?
- Light
- Concentration of CO2
- Temperature
