Growth of Plant under Different Colored Light Problem: Does the color of light affect the plant growth? Hypothesis: Red color will have the most impact on the plant growth‚ meanwhile; black will have the least impact on the plant growth Variables: • Dependent Variable is the color of light • Independent Variable is the type of plant used Materials/Apparatus: • Plants (of the same type) • Water • Ruler • Colored Construction Paper • Colored Transparent Print Paper • Lamp with Incandescent

The effect of light quantity on photosynthesis of green land plants Introduction Photosynthesis is the process of converting light energy into chemical energy (Hoober 1984). Pigments within chloroplasts‚ primarily chlorophyll‚ absorb the incoming solar energy which excites their electrons (Hoober 1984). These pigments exist in photosystems in the thylakoid membrane of the chloroplast (Ladiges et al.2010). As the electrons return to ground level‚ they are captured by the electron acceptor in the

Why did plants exposed to no light grow better than the plants exposed to light? The plants exposed to no light performed better than those exposed to light is most likely caused by the plants exposed to no light having more water than those in light. Even though the amount and frequency of water added to all plants were kept the same‚ the amount of water the plants in no light had access to was more than the amount of water the plants in light had. This is due to two reasons: a) because the plants

bless you! Cassien TWAGIRIMANA ABSTRACT The Irish potato is one of major food tuber crops grown in Rwanda. It plays a key role in food consumption‚ nutritional security and reduction of hunger. Potato plant like other tuber crops requires sufficient supply of several essential elements for proper growth and function. It is a gross feeder and exploiting greater volume of soil nutrients including nitrogen‚ phosphorous‚ potassium and water. Potato production has become very important in Rwanda in terms

composed to show the effects that different colors of light have on plant growth. We separated our plants into different boxes and then covered the openings with colored cellophane. We conducted this experiment for approximately two weeks. Out of the colors blue‚ green‚ red‚ and yellow‚ the plant behind the blue cellophane grew the most. Research Problem What effects does different color light have on plant growth? Hypothesis The plants will grow taller under the red and blue light opposed to the

May 2012 The Effect of Light on Snapdragon Flowers Introduction: It is a well-known fact that plants need light for nourishment‚ yet many people are ignorant of the reasons behind this. The biological process by which green plants utilize carbon dioxide‚ water and sunlight to form their own food is called photosynthesis (unknown). Past research has demonstrated that red and blue rays maximize this process (Rothenburger‚ 1993). The purpose of this experiment was to examine the effect of several different

The Effects of Changing Wavelength on Raphanus Sativus Abstract: Light from the Sun is a full spectrum of different wavelengths of light. Scientists refer to this light as “white light”. When the wavelength of visible light changes‚ so does the color seen by the eye. The shortest wavelengths visible to the human eye are violet (400 nanometers). The longest wavelengths visible the human eye are red (700 nanometers). Each plant is affected differently by the changing wavelengths of light. The purpose

ABSTRACT An experiment was carried out at the Horticulture Farm‚ Bangladesh Agricultural University‚ Mymensingh during 1998-99 growing season to study the effect of nitrogen and plant spacing on the growth and yield of potato (var. Diamant). Different nitrogen levels viz. 0‚ 127.0‚ 190.5 and 254.0 kg N/ha significantly influenced plant height‚ foliage coverage‚ number of main stem per hill‚ days required for 80% maturity of the crop‚ fresh weight of haulm (g/hill)‚ number of tubers per hill‚
