elodea lab photosynthesis will be available on

Is because
the wants to show that the rates of photosynthesis will
vary according to how much light from a light bulb will be trapped in
the chloroplasts, in the leaf.

How does this investigation demonstrate that plants give off oxygen during  photosynthesis?

My graph has no anomalies, and it closely followed to what I had
predicted that the closer the distance of the light the higher the
rate of photosynthesis would be and thus produce more bubbles in the
time recorded.

Effects of different colors of light on the photosynthesis rate.

How does the rate of photosynthesis change when sodium bicarbonate is added  to the water?


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

Photosynthesis Lab - Elodea O2 Bubbles - Duration: 1:41

How does light intensity and duration affect the rate of photosynthesis?

The beginning aquarist is likely to think that if there's enough light to see then it's enough for plants to grow.
However, that's not true. If you want to grow healthy plants, and not just algae, you need enough light for them to use for photosynthesis and create energy.
It used to be that people advised 3-4 watts per gallon as a VERY basic principle. But, due to modern lighting technology this is now considered an outdated notion (with PAR now more the norm).

This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...

Photosynthesis Lab: Elodea Plant - Prezi

In our experiment we put baking soda in in our Elodea plant so as the days went by the Elodea plant started losing color and the bubbles started to disappear.

Lab: Exploring the Rate of Photosynthesis - The Biology …

so now I know that if I ever put an Elodea plant in my fish tank to never put baking soda or salt in there because the plants would just die and give off less oxygen like how it did in my experiment.

Photosynthesis Lab:
Elodea Plant Hypothesis: Question: I think the carbonated water elodea plant will produce more oxygen then the pure watered elodea plant due to the baking soda acting as energy for the elodea in a way Materials: 4 Beakers, Baking Soda, Elodea Plants, Water, Mixing Stick, 4 Test Tubes, & Light Source Procedure: Data: Analysis: Conclusion: Possible Errors: Summary: We could have had many possible errors.

Light wavelength effect on the photosynthetic rate of ..

I think this because the plant may use up all of the carbon dioxide (Sodium hydro carbonate) and the plant can have as much light as it needs but if it does not have any carbon dioxide it will not be able to photosynthesise....
