The Effect of Different Colored Light on Plant Growth
The Effect of Different Colored Light on Plant Growth
Results
I measured each plant on days 7, 9, 11, 13, 15, 20, and 32, after planting. The plants under the green cellophane grew the most in every measurement. The biggest growth spurt for the plants under the green cellophane was from day seven to day nine. By day 13, the plants under the purple and red cellophane started to grow at similar rates as compared with those under the green cellophane. By day 32, the plants underneath the green cellophane were the tallest, with an average height of 38.3 cm. The plants under the clear cellophane experienced the least amount of growth at every measurement except day seven. For the first 15 days, there was no differentiation in number of leaves. By day 32, the plants under the clear cellophane had the most leaves, with an average of 5.9 leaves per plant.
Conclusions/Discussion
Different colors of light do seem to lead to a different growth rate. Plants grown under green cellophane grew taller and faster than plants grown under other colors of cellophane. In the future, I would put different types of plants underneath the same color of cellophane to see if the light had the same effect that it did on the pole bean plants. I would also weigh the plants to find out their overall mass. I would also find out how much sugar is being produced by photosynthesis

Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases and bacteria makes it useful for food packaging.
It's clear, it's handy, and it's wrapped around my candy. The cellophane wrap is one of the most versatile discoveries of the 1900s. Intended to be a protective textile, the cellophane has since found application in many industries as a packaging material and as a semi-permeable film.

Many people mistake cellophane for plastic. The truth is the two materials are of completely different composition. Plastic is a synthetic or

    References: to the ‘amount of light / water’ were accepted as equivalent to light intensity and volume of water, respectively, however students should always be encouraged to use appropriate scientific vocabulary whenever possible. Other creditworthy answers that were seen included age or size of shoots, temperature and soil type. Suggestions such as ‘time’, ‘direction of light’, ‘type of box’ and ‘black plastic used’ gained no marks. Students should always be as specific as possible in answers – responses such as ‘type of conditions’ and ‘surroundings they are grown in’ were clearly weak and gained no credit.…

    For this project we had to experiment to see the effects of blue light on a plants growth. We had to research on light and its effects on photosynthesis. This helped me with my experiment because I had knowledge for what was going on with the plants and light. For this project I and one of my classmates had to conduct a experiment to see the effects of blue light versus white light. For this project we had to grow lentil beans under white and blue light and water and measure them daily. My experimental question was what is the effect of blue light on the height of lentil beans?…

    The purpose of this experiment is to see under what conditions the elodea plants grow and photosynthesize the best. To accomplish this, the plants were subjected t different light colours (Blue, Green, Red and purple). This test will allow us to see which wavelength (colour) will allow the most light the elodea plant needs to flourish. Besides the light factor I also decided to put a 100 watt lamp above each plant so I get a high light intensity to speed up the rate of photosynthesis.…
