Chapter B8- Photosynthesis Flashcards
What is the word equation for photosynthesis?
What is the balanced symbol equation for photosynthesis?
What type of reaction is photosynthesis and describe it?
What are the four main limiting factors of photosynthesis?
What type of chemical reaction is glucose used for?
What is glucose converted into?
What is glucose used to produce and for what reason?
What is glucose used to also produce in plant cells?
What is glucose used to produce and for what reaction?
What type of molecules does glucose produce?
Carbon dioxide+Water—Glucose+Oxygen+Energy.
6CO2+6H20—C6H12O6+6O2+Energy.
It is an endothermic reaction in which energy is transferred from the environment to the chloroplasts by light.
Temperature, light intensity, carbon dioxide concentration, and the amount of chlorophyll.
Respiration.
Insoluble starch for storage.
Produces fats or oils for storage.
Produces cellulose, which strengthens the cell wall.
Produces amino acids for protein synthesis.
Produces proteins.
What mineral ion do plants use that are absorbed from the soil?
What is light energy proportional to?
What distance is this?
What is the equation for this?
What two things can affect the amount of chlorophyll in a plant (give examples)?
What two things can these factors then cause to the chloroplasts?
What does this then result in and why?
Nitrate ions.
Distance.
The distance from the light.
1/d2 (distance squared).
- Disease (e.g. infection with the tobacco mosaic virus)
- Environmental stress (such as lack of nutrients).
Cause the chloroplasts to become damaged or to not to make enough chlorophyll.
This means the rate of photosynthesis is reduced because they can’t absorb as much light.
What is an example of a method to increase the rate of photosynthesis for the following limiting factors:
Light intensity
Increasing temperature
Increase CO2 concentration
Supplying artificial light- to increase the light intensity
Adding a heater- to increase the temperature
Adding a paraffin heater (which as it burns, releases CO2 as a bi product) to increase the CO2 concentration.
