music possesses properties that affect the growth rate of plants in different ways. These properties may be the wavelength of the music‚ its frequency or even its tempo. According to a study conducted by Margaret E. Collins and John E. K. Foreman‚ entitled The Effect of Sound on the growth rate of plants (2001)‚ plants growth is directly affected by sounds of varying frequencies. They observed that when plants are exposed to pure tones‚ it affects the growth of the plant. This was due to the transverse

How the Amount of Water Effects Plant Growth By Dennis Marchuk Turner Ashby High School Grade 10 March 23‚ 2013 The purpose of this project was to determine how much the amount of water effected plant growth. This had been accomplished by taking three groups of plants and placing them next to one another. Each group contains two plants. Each one would be watered with a different amount of water. They would then be measured how much they grew. The growth of the three plants was compared

Colour of Light Effects on Plant Growth Introduction Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. Plants need water‚ Co2 and light energy to create sugar. Photosynthesis occurs mainly in leaves and in 2 phases: light reaction and dark reaction. The light reactions converts light energy to chemical (Biology.clc.uc.edu‚ 2014). This chemical reaction must take place in the thylakoid membrane. Chlorophyll (the green pigment involved

see how the wavelength of visible light affects the rate of growth of aquatic plants Different wavelengths of light will effect to rate of photosynthesis. I will test this by exposing the pondweed to different wavelengths of light to see how it reacts. Method I will do this by passing white light through a filter. The filter will remove all unwanted wavelengths of light leaving the plant exposed to only the desired wavelength of light. I will use three different wavelengths of light 750nm

Influence of light on the growth of young tomato‚ cucumber and sweet pepper plants in the greenhouse: effects on relative growth rate‚ net assimilation rate and leaf area ratio. Scientia Hortic.‚ 31: 161-174. Tomato‚ cucumber and sweet pepper were sown in a greenhouse at regular intervals throughout the year. A relationship between the relative growth rate (RGR) of these young plants and the mean daily light integral ( PAR incoming per unit ground area) could be calculated for each species. A growth analysis

to be rather slow as very little growth could be observed. After the several days of being under the scorching sun the leaves of the tomato plants started to dry up and would fall off at the very touch of it. More water had to be added to them to further hydrate the plants. It was only after around 30 days that a concrete growth could be observed. The plants grew to a reasonable height and needed to be attached to a bamboo stick so as to remain stable. The growths of the tomatoes themselves were tremendous

High School Department General Science How Does Phosphate Affect the Growth of Aquatic Plants? (A Problem Proposal) I. Introduction Aquatic plants are an important component of lake systems. These plants may be totally submerged beneath the lake surface‚ floating‚ or growing along the shoreline. They provide food and shelter for bugs‚ fish and other organisms‚ prevent shoreline erosion‚ filter pollutants from adjacent shoreline activities‚ and

What is the Effect of the Colour of Light on the Rate of Photosynthesis? By Amelia Rowan‚ 12SDa Aim To discover whether the colour of the light source has any effect on the rate of photosynthesis of a sample of algae. Hypothesis It was predicted that the colour of the light source would have a very slight effect on the rate of photosynthesis. It was further predicted that when the sample was placed under the green light‚ the rate of photosynthesis would be the lowest. This hypothesis was arrived

Plant Growth; Varying Light Exposures Intro and Hypothesis: The problem that is going to be answered is: will plant seeds grow at differently if they are covered by different materials while exposing them to the same amount of light? Also‚ which material will allow the plants to grow the most‚ tin foil‚ saran wrap‚ paper or no covering? Before the lab took place‚ it was hypothesized that the less light a plant receives‚ the less it will grow and the more light it receives‚ the more it will grow
