Photosynthesis Flashcards
Equation for photosynthesis:
carbon dioxide + water
->(light energy)->
glucose + oxygen
Light energy is absorbed by what during photosynthesis?
A green substance called chlorophyll.
Carbon dioxide for photosynthesis is acquired from where?
The air.
Water for photosynthesis is acquired how?
From the soil.
Oxygen is released as a what of photosynthesis?
By-product.
Rate of photosynthesis can be limited by:
Shortage of light.
Low temperature.
Shortage of carbon dioxide.
Glucose from photosynthesis can be stored as what?
Starch as it is insoluble.
Plant cells can use some glucose produced by photosynthesis for what process?
Respiration.
Glucose in plants and algae can be used:
To produce fats or oil for storage.
To produce cellulose that strengthens the cell wall.
To produce proteins.
To produce proteins a plant needs other reactants than glucose. What are these?
Nitrate ions.
