Photosynthesis Flashcards
What is photosynthesis?
The process plants use to make their own food
What do plants need to photosynthesise?
Water
Co2
Light energy
What does photosynthesis produce?
Food- for plant
Oxygen- byproduct
What else do plants need for photosynthesis?
Why do they need this?
Chlorophyll
Green pigment to absorb light energy and convert it into chemical energy in food
Word equation for photosynthesis?
Carbon dioxide
Water
Light energy
Chlorophyll
Food
Oxygen
Balanced symbol equation for photosynthesis?
6co2
6h2o
C6h12o6
6o2
Where does photosynthesis take place?
In all the green parts of a plant
Inside organelles called chloroplasts
What affects photosynthesis?
What do they act as?
Light intensity
Water
Amount of co2 in air
Temperature
Limiting factors
How does the amount of light effect photosynthesis?
The more light, the more energy there will be for the plant to grow, so it will photosynthesis faster
Why do experiments need to be repeated more than once?
To make the result more reliable by eliminating random differences like different sized leaves
What is the best colour of light for photosynthesis?
Yellowy orange
