elodea photosynthesis experiment worksheet

Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react....

In this experiment we were told that we would be measuring the rate of photosynthesis.

Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise.


photosynthesis in elodea with picture

The rate of photosynthesis was recorded at a range of light Intensities and conditions.

It could also be due to light
coming from other sources to our experiment causing the rate of
photosynthesis to rise with the light coming in though I do not know
however how this could have happened in all 3 experiments.


elodea photosynthesis experienment temperature

Effect of different colors of light on the rate of photosynthesisThe effect of different lights on plant growth: incandescent light, fluorescent light, sunlight and black light.

effect of wavelength on photosynthesis rate

A) sunlight concentration B) temperature 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....

Variables

Input - Light intensityis to be varied by increasing and decreasing
the distance from the light source to the plant

Output - The rate of photosynthesisis to be measured by counting the
bubbles of oxygen produced by the plant every two minutes, and
therefore finding the rate of photosynthesis

Control - The amount of water available to the Elodea will stay the
same level in the 400 cm3 beaker.

effect of temperature on photosynthesis in elodea

The colour of the lamp will stay the
same (yellow) as to plants Chlorophyll easily absorbs blue light,
however it does not easily absorb green or yellow light, rather it
reflects it, this decrease's the rate of photosynthesis.

Introductory school investigations of photosynthesis include the evolution of oxygen by Canadian pond weed (Elodea canadensis), Cabomba caroliniana* or Ceratophyllum demersum, or testing for starch in Pelargonium leaves that have been decolourised. Both methods are difficult to quantify, and the second method often misleads students.
