Explanation / Answer
1.Reactants of light reaction is- water,light energy
2.products of the light reactions are- ATP, NADPH, and oxygen.
3.Reactants of dark reaction- ATP, NADPH, and CO2.
4.Products of dark reaction- glucose .
5.Water returns to the roots along with some carbohydrates made by photosynthesis and some water is released in the atmosphere by transpiration.
6.e. A dependent variable is what is measured in the experiment and what is affected during the experiment.
Water amount,
f.plant species
7.Indepandent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.These are a) Heater b) Fan c) Lamp .
8.A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable.
d.normal conditions.
