Rate of Photosynthesis and How It Varies
There are several things which need to be taken into account which can
cause the rate of photosynthesis to change.
A) sunlight concentration
C) chlorophyll concentration
D) carbon dioxide availability
Effects of the variables and there concentrations:
The amount of sunlight will decide the rate of photosynthesis as there
will be a an increased rate of photosynthesis due to the increased
availability of photons of light. This light energy can then be
transferred to chemical potential energy. The energy is then
distributed around the plant and used for various reasons around ...view middle of the document...
Due to this, there are a lot of
things which need to be done to make sure that the temperature remains
constant. Due to this, there is a major advantage when manipulating
the variable, and so, a control can be manipulated and made to work as
made. As a result the rate of photosynthesis is calculated.
the rate of photosynthesis decreases with decreasing light
intensities, and so the more light there is, the greater the rate of
With a reduction is the amount water that is being supplied to the
plant, there is also a reduction in the rate of photosynthesis too.
This is very hard to control and examine, as the process is within the
plant and very complicated processes have to be radioactive water has
t be used in order for the fact to be determined that water is
actually used in the reaction. The radioactive water is used as a
tracer, and so, thus, the water can be seen to be used in the process
of photosynthesis. As a result, it can be determined that there is a
need for the water in the [process of photosynthesis, and so, the
result of less water going into the plant will result in the plant
photosynthesising. However, this experiment is not feasible for labs
at the school, and can only take place in the sophisticated labs in
only conducted at degree level.
The control of the amount of carbon dioxide will be easily carried
out, and the...
