Effects of different colors of light on plant growth.

photosynthesis A. sunlight is absorbed by chlorophyll in a leafB. carbon dioxide is taken in from the airC. water is transported from the rootsD. glucose is synthesized and distributed throughout the plantE. oxygen is released

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....

The effect of light on seed germinationWhat is Transpiration?

Effect of different colors of light on the rate of photosynthesis.

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

In addition, a trial with no light would show the effect of light versus no light in the plant’s production of photosynthesis.
Other variables that we could tweak are concentration of bicarbonate and type of plant.
Comparing experimental results
By: Emily, David, Michael

The word equation for photosynthesis is: Light [IMAGE]Carbon Dioxide + Water Glucose + Oxygen Chlorophyll Although most of the glucose produced is converted into insoluble starch for storage in the stem, leaves or roots, some is used immediately by the plant to provide via respiration....

Investigate the effect of light on seed germination.

6CO + 6H O ® C H O + 12O (in the presence of light energy and chlorophyll) Aim- The aim of the experiment is to determine what effect light intensity has upon the rate of photosynthesis of Canadian Pondweed (Elodea)....

Introduction: "Photosynthesis is the conversion of light energy to chemical energy that is stored in glucose or other organic compounds; it occurs in plants, algae, and certain prokaryotes" (Campbell, G-16).

Effects of different colors of light on the photosynthesis rate.

Cover the several lights with red, blue, green, and yellow films.

Record or report findings.
Rate of photosynthesis (measured by ET50, time it took for 50% of the leaf disks to float up)
Color of light (wavelength of light)
Light intensity, temperature, bicarbonate concentration (0.2%), depth of bicarbonate solution, direction of incoming light, pH, amount of soap, size of leaf disk, type of plant
Ten trials for each color, however for each trial, a few disks did not float up.

The Effect of Green Light on Plants | Hunker

Looking at the graph, the plant under white light had the greatest 1/ET50 value, followed by blue, red, yellow, and green.

The team’s hypothesis was supported because the average time it took for the leaves under green light to float was greatest, and white light the least.

The Effect of Green Light on Plants By Anna-Karin Smith Anna ..

Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease.

The Effects of Different Light Colors on Photosynthetic Rate

During the process of photosynthesis, carbon dioxide plus water in the presence of sunlight, enzymes and chlorophyll produce glucose and oxygen as waste product.

The effect of Light Colour on ..

6CO + 6H O = C H O + 6O The factors that effect the rate of photosynthisis are the amount of light, the amount of carbon-dioxide (CO ) and the temperature that can be used by the plant....

Effects of Blue Light on Plants – Greenhouse Product …

However, there is still a large spectral region between 500 and 600 nm where chlorophyll absorbs very little light, and plants appear green because this light is reflected.

Effects of Blue and Red Light on the Rate of Photosynthesis

It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .

The Effect of Light on Photosynthesis :: Papers - …

We have also learnt that photosynthesis is a vital process that occurs in order to create glucose and oxygen, by transforming carbon dioxide and water in the presence of light energy.
