GCSE Additional B2- Photosynthesis
Cards in this deck (8)
- 1Photosynthesis equation...Carbon Dioxide+Water==>Glucose and Oxygen
- 2Photosynthesis symbol equation...CO2+H2O==>C6H12O6+O2
- 3Photosynthesis is...The process in which plants make food for themselves.
- 4Chloroplasts..Photosynthesis is what takes place here, these structures are full of chlorophyll. Light energy is absorbed by the green substance -chlorophyll.
Reminder: ChloroPHYLLS up the chloroplasts. - 5Guard cells...CO2 enters though the guard cells' stomata, these stomata then keep in CO2 during the day and let in O2 during the night.
- 6How is Photosynthesis used?The process is used by converting the CO2 from the air and the water from the soil into sugar (glucose).
- 7The uses of a plants structure...-Carbon Dioxide is diffused into the leaves
-water enters through the roots via the xylem tubes
-Sugar is transported around the plant via the Phloem tubes
-Chloroplasts absorb the light from the sun
-Stomata is for the gas exchange of Carbon Dioxide, Oxygen and water vapour - 8Factors that will affect a plant's photosynthesis rate...-A shortage of light- the higher the light intensity, the faster the rate of photosynthesis
-Low temperature can also slow down the rate
-A shortage of carbon dioxide is another staler for photosynthesis
